A.A.R. Combination Railroad Track / MTS Scale

NOTE: This manual is intended to compliment and be used in conjunction with the Certified Prints provided by FAIRBANKS SCALES. Installation should be attempted only with the presence and guidance of experienced personnel who are fully familiar with the assembly of these scales. Please read this Bulletin in its entirety BEFORE setting scale hardware.

SECTION 1-A: Introduction & General Description:

The 2000 Series Rocker Column Railroad Track Scale is a factory assembled, fully electronic scale available in single 12' 6" long, and double 25' long welded steel modules. The 2000 Series is designed for above ground or shallow pit installation, and is configured to accept a 115# ARR rail. The scale can be configured to accept other sizes of rail as a special order.

50614_1

The design of the 2000 Series Railroad Track Scale incorporates hermetically-sealed, stainless steel rocker column load cells, each with a capacity of 110,000 lbs. The combination of a level approach, rocker column load cells, and checking system permits the scale slight movement to mitigate the forces applied to it.

Each module features four removable panels for service access. Interface to a Fairbanks 2500 Series Digital Weight Indicator with INTALOGIX technology is standard. The purchased scale will include the modules, anchor bolts, loadcells, checking system, smart sectional controllers, power supply, and ground rods.

1-C: Rails & Anti-Creep Devices

The Scale is designed to accept a 115 lb. rail with Foster #62 rail clip. The approach rails and Scale Weigh Rail should be the same weight. The approach anchor bolts, approach rail plates, rails, rail clips, and anti - creep devices are all optional items. They can be supplied by Fairbanks Scales when ordered as accessories, otherwise they are not supplied.

Positive means must be provided to prevent the creeping of the approach rails and to maintain a clearance which shall be not less than 1/8 inches or more than 5/8 inches between the approach rails and the weigh rails. Switch points are highly recommended for the purpose. A minimum of seventy five (75) feet of tangent track at each approach is required by the A.A.R. (Association of American Railroads).

1-D: Regulations:

This Scale is designed and manufactured in accordance with regulations established by Handbook 44 as adopted by the National Conference of Weights and Measures (NCWM), the American Association of Railroads (AAR), and the National Institute of Standards and Technology (NIST). If the Scale is intended to provide weights to the serving railroad for the purpose of revenue, it shall be installed, repaired, tested, and maintained in accordance with the Association of American Railroads Scale Handbook, which contains the rules and specifications for the construction and maintenance of track scales for the weighing of railroad vehicles.

Excerpts from the Association of American Railroads Scale Handbook

Location: Scale shall be so located that an adequate foundation and at least 75 feet of

tangent track at each approach to the weighrails can be provided.

Elevation:

In areas with poor drainage, the scale shall be raised to such an elevation that

drainage of the surface water shall be away from it. Means shall be provided to prevent accumulation of water at the scale site. Solutions for saturated areas with poor drainage shall be determined by a competent soils engineer.

Drainage: The pit floor shall be pitched to a common point for drainage and shall be smooth and free from pockets in which water may stand. If the pit floor is below substrate water lever, the pit shall be drained from its lowest point into a sump adequately equipped with automatic means for removal of water as it collects.

Footing or Piers for loadcells:

Concrete footings or piers supporting loadcell base plates shall not be less than 18 inches thick. Their tops shall be above the floor a sufficient distance to prevent the accumulation of water around or under the base plates.

Pit floor:

The floor of the pit may be a mat of concrete approximately as thick as that required to support the loadcell base plates or, if local conditions permit, the thickness may be reduced to no less than 6 inches.

Page 9

03/10 9 50614 Rev. 5

Ventilation: All scale pits shall be ventilated to meet the needs of each particular case to minimize the relative humidity in the pit and to retard corrosion of scale parts and structural steel.

Entrance to the Scale Pit:

Suitable access to the Scale pit shall be provided. The entrance

shall be closed by a suitable closure fastened to prevent the entry of unauthorized persons.

Bearing Pressures Under Foundations:

The bearing areas of the foundation footings

shall be such that the pressure under the footings will not exceed:

For fine sand and clay .................................. 4,000 lb. per square foot

For coarse sand or hard clay ....................... 6,000 LB per square foot

For boulders or solid rock ........................... 20,000 LB per square foot

If the soil does not have a bearing capacity of at least 4,000 lb.. Per square foot, and its bearing capacity cannot be increased by drainage, stabilization, or other means, pile foundations shall be provided. Careful soil exploration, including borings, is always desirable.

Leveling:

Loadcell assemblies shall be raised or lowered, as required, by means of leveling screws, shims, or other methods to bring the weighbridge into level traversely and on grade longitudinally. After leveling the loadcell baseplates, to a tolerance of not more than

0.015 inches per foot, they shall be grouted as required.

Scale House Design:

Except where the indicating elements are mounted in a separate building, a Scale house large enough to install, observe and service the indicating elements shall be provided. It should have windows of sufficient size and so located as to give the weigher an unobstructed view of the Scale deck and approaching cars or trucks.

Where a special scale house is required, a suitable and substantial building shall be provided. To insure proper operation of the indicator and/or recorder, the house shall be equipped with proper environmental control.

Scale House Location:

The lateral clearance between the Scale house and centerline of Scale or any track shall not be less than 8 feet, unless otherwise required by law, or the serving railroad.

Indicator - Recorder Shelf: If a shelf is required for mounting the indicator and/or recorder, it shall be so located as to provide for ease of operation without obscuring the weigher's view of the Scale deck and approaching cars or trucks. The shelf must not limit ready access to the instrument for maintenance purposes.

1-E: Foundation Construction & Installation

Use only certified prints that are marked for the particular installation, customer, and scale.

All the dimensions indicated on the certified prints must be rigidly and faithfully followed during all phases of construction. There is very little tolerance for misplacements and mistakes. Pier heights are especially critical as there must be enough space for finishing grout under all stands (per certified drawings) while rails on the scale weighbridge and approach rail must be absolutely level.

Placement of foundation bolts is absolutely critical to the successful installation of the scale. The use of a template or form that matches the design called for can be used. Foundation bolts must NOT be installed at an angle, too deep, or too shallow. Very close tolerances must be met on all aspects of pit construction.

1-F: Grout Plates

The Grout plates are the foundation upon which the scale structure rests, and their level, accurate position is basic to the entire structure. Base plates must be installed at proper height and in the same plane. All grout plates must be level within .015" per foot. All pier bolts must have enough height to allow vertical adjustment of the base plate's, but not so high as to interfere or to have insufficient depth into the pier.

1-G: Rocker Column Loadcells

The 110,000 lb capacity compression loadcells are designed to meet the most stringent accuracy requirements. They offer total stainless steel construction and complete hermetic sealing, making them suitable for use in the toughest of environments. They are rated IP 68.

The load cell's Rocker Column design permits it to be self aligning, always returning to its original plumb, square, and level position after loading and unloading disturbances.

1-H: Ground Rods:

Ground rods are essential in providing protection to the electronic components and loadcells from both lightning surges and static discharges. Pit ground rods shall be tied to the foundations steel reinforcement rod (rebar) prior to pouring, and shall protrude 4 inches above the pit floor. Ground rods for approach rails shall be tied to the rebar assembly. There are five (5) rods with the locations specified as below:

Page 12

03/10 12 50614 Rev. 5

The following drawing shows correct placement of ground rods.

Above example #3: Double / Double

1: Clean all ground rod end(s) with abrasive to assure a good electrical connection. Keep all ground straps untwisted, clear of standing water, with a drip loop, and as short as possible. Secure the strap to the ground rods with the provided clamp and coat with grease. Cover the connections to protect from condensation.

2: Connections to the weighbridge are installed by bolting to the provided bracket at the end of each Scale Module. Scrape / sand enough paint / coating away to make a good electrical connection, and coat with grease AFTER the connection has been made.

3: Ground rod #5 should be located near the interface conduit. It is used to connect to the isolated ground of the Pit Power Supply (PPS) Acc 2001-1 only.

4: #1, ,2, 3, 4, and 5 Ground Rods are provided. These should be installed and correctly connected with ground braid to the Anti-creep assy's with the provided hardware. Refer to illustrations 50614_5, 50614_6, and Appendix VII. Ground rod connections 6, 7, and 8 are not shown and are not provided by Fairbanks. Refer to 2-K: Grounding on page 30 for further details.

2-G: Foundation Inspection

Excerpts from Fairbanks Scales form FF-2267; Foundation Field Check list

A Foundation Inspection should ALWAYS be performed prior to Scale installation, to confirm the Foundation is constructed correctly and is ready for installation. If possible, this should be done prior to the scale shipment.

TOOLS REQUIRED:

Certified drawings and site plan. 2' to 4' level 25' & 100' steel tape measures Hammer and concrete nails Hacksaw laser or builders level if possible String line (construction string) straight edge for pit foundations Construction Spray Paint (upside down type, for marking concrete)

Perform the following Foundation checks. It is recommended to keep a copy of the check list with the job file. ALWAYS familiarize yourself with the CERTIFIED FOUNDATION PRINTS for the job you are working on as model numbers and their specifications are subject to change.

1: Site Plan and Certified Prints should be thoroughly reviewed to confirm accurate locations to the scale and all extra items ( scoreboards, lights, poles, etc.) that are included.

2: Check for truck and crane access, overhead wires, fences, green concrete, etc. .

3: Dimensional length and width check; check all 4 sides and record on chart.

4: Diagonal measurements check to verify that the Foundation is square and record on chart.

These measurements should be equal, or within ½ inch. Greater error could result in the scale not fitting in the Foundation.

5: Check ALL pier heights to make sure they are at the correct elevation and record on chart.

6: Check the pit walls to verify they are straight.

7: Verify Ground Rod locations.

8: Verify conduit locations and pull strings.

9: Verify that drains and sump openings are piped correctly are clear of debris.

10: Check the end coping to ensure they are centerline and that the coping is correct for the

scale being installed (10', 11', 12', width, etc.). Check all coping, side and end, for hollow areas.

11: Verify location(s) of any and all required embeds

Record all measurements and observations. Physically mark any discrepancies with the marking paint. Do not proceed with Installation until corrections have been made.

6: Place wooden blocking and cribbing material suitable for supporting each module into position near each pier and grout plate. Each section will require four points of support, therefore arrange the placement of these supports accordingly. It is recommended to set blocking to support the module 1 to 2 inches higher (than the certified prints indicate its final elevation should be) at this time.

7: With a crane and rigging (4 leg drop) of suitable capacity, install each module onto the supporting blocking.

Note: On pit installations, remove the access panels on the module(s) before setting.

14: When the weighbridge is completely set on plumb load cells, ensure ALL modules are on the same plane. If necessary, loosen the grout plate pier bolts and adjust the three (3) leveling screws in each grout plate. When complete, re-tighten the grout plate anchor bolts tight enough to ensure they do not shift.

Baseplate Leveling Screws

15: Double module installations contain a middle section. For the middle sections, the elevation reference is both the absolute level of the main beams with respect to the end sections, and the equal loading of the loadcells that support the middle of the scale. Adjust the grout plate leveling screws to level the modules. Alternately, a transit can be used to compare and maintain elevation, and a tightly stretched mason line.

16: Providing a suitable power supply to connect to the loadcells, measure and record the mV/V output from each loadcell in the scale. The resulting readings will indicate the current weight distribution of the scale's deadload among the six (6) points of support. The outputs will be greater for number's 3 and 4 because there is physically more deadload weight upon them.

50614_29

This final grout plate elevation adjustment should be made to match the mV/V outputs of the load cells to assure correct distribution of the scale's deadload among the six (6) points of support. Adjust the grout plate leveling screws (equally) to match loadcells 1, 2, 5, and 6. Then adjust to match loadcells 3, and 4. When this has been completed, ensure each loadcell grout plate is level to within .015" per foot.

NOTE: The loadcell numbering sequence shown is designed for interfacing Fairbanks INTALOGIX technology instrumentation.

Single modules are supported by two sections, or four load cells. A final grout plate elevation adjustment should be made to match the mV/V outputs of the load cells to assure correct distribution of the scale's deadload among the four (4) points of support. Adjust the grout plate leveling screws (equally) to match loadcells 1, 2, 3, and 4. When this has been completed, ensure each loadcell grout plate is level to within .015" per foot.

NOTE: The loadcell numbering sequence shown is designed for interfacing Fairbanks INTALOGIX technology instrumentation.

17: Perform a final check to all:

Loadcell grout plates are level to within .015" per foot.

All Load cells are vertical and plumb

Top flanges of the main beams are absolutely level and on the same plane as the end sections.

There is correct distribution of the scale's deadload among the loadcells.

All assembly hardware is secure and tight.

When complete, recheck to ensure all Grout Plates and Loadcells are plumb, square, and level.

2-J: Grouting the Grout plates:

Grout becomes the base which supports the entire structure. Grout MUST be fully supporting the grout plates with NO gaps or spaces. A good method is to build the forms slightly bigger than the plate to permit the pouring and the rising of the grout mixture. The pier should be thoroughly saturated with clean water for a minimum of 4 hours. This will both prevent the dry pier concrete from absorbing water from the mix as it is poured, and greatly enhance the ability for the grout mix to bond with the pier.

1. Grout selection:

• Grout shall be precision, packaged dry, non-metallic, hydraulic, non-shrink, and nongaseous.

• Grout shall meet or exceed ASTM C-1107 and Corps of Engineers CRD-C621.

• Grout shall be bleed free and attain a minimum

of 5000 psi compressive strength in 28 days

at flowable consistency.

• Grout MUST be mixed to a flowable consistency as specified by the grout manufacturer.

• Do not permit any loads upon the scale until the grout has reached the compressive strength of 2500 psi per the grout manufacturers instruction.

2. Surface preparation:

• Surfaces to be grouted shall be free of loose debris, grease, oil and other contaminant’s.

• Contaminant’s shall be removed using caustic soda or other approved concrete cleaners.

• All surfaces shall be flushed with clean water.

• Prior to pouring, all surfaces should be saturated with clean water for a minimum of 4 hours.

3. Forming:

• Forming must be completed and installed before starting to pour grout.

• Forms shall be slightly larger (three to four inches) than the dimension of the grout plates.

• Forms shall be of sufficient strength, anchored properly, and sealed. Seal with caulk and use a form release agent on forms if required. Leave access for pouring grout in a convenient place.

4. Mixing and Pouring:

• Mix grout per instructions on bag until a very smooth, pourable mix is obtained. Be sure you mix enough quantity for the form you are filling.

• If necessary, use a large funnel or cone to direct mix into form and under stands.

Page 29

03/10 29 50614 Rev. 5

• Pour the grout mix from one end until it fully reaches the other side and rises to fill the form completely. By using this method, there will be no gaps or air pockets. Vibrators are not recommended due to the danger of disturbing the placement of the loadcell base plate(s). Ensure the grout mixture totally fills all voids.

Trim grout at an angle for the entire grout base

50614_32

• The A.A.R. requires that IF grout extends beyond the base plate, it be sloped away from the base plates and stands so that water will not pool and saturate the metal, thereby rusting it. The form may be larger than the base or stand by about 3" on all sides. *When grout is firm but can still be shaped, angle all four sides of pour down and away from the base plate or stand.

• Do not allow any movement before grout is completely set. When grout is fully cured, remove forms.

• When forms are removed, remove base plate leveling screws completely and discard then. Fill the empty holes with silicon caulking. Tighten all loadcell base plate pier bolt nuts to 250 Ft pounds

Bolt the approach rail columns to the grout plates

When the grout has cured per the grout manufacturers instruction, the scale is ready for testing and service.

1. Remove all grout forms.

2. Remove all leveling screws from the base plates. Fill the empty holes with rubber caulk-

ing.

3. Tighten all grout plate nuts and bolts

4. Adjust and shim all Check brackets for 1/16" Minimum to 1/8" Maximum clearance.

Ensure the scale modules exhibit free movement within the confines of the check brackets, and that when the scale modules are undisturbed they do not contact the checking posts.

NOTE: If the scale leans to any one side or does NOT return to a centered position, the load cells are NOT plumb. You can ONLY plumb load cells when the scale's checking is touching ALL surfaces and the platform cannot move laterally in any direction.

APPENDIX VIII: Concrete & Slump Testing:

Concrete is produced from the mixing of sand (fine aggregate), stone (coarse aggregate), cement and water. The water combines with the cement to form a fluid paste often referred to as "plastic". The paste is combined with the sand and stone to make a workable "plastic" concrete that can be poured, shaped, smoothed, and molded. The plastic concrete then hardens around the sand and stone forming a solid mass. Concrete in it's plastic state can be formed into structures such as pavements, walls, or footings. When the plastic concrete hardens, the structures formed can then support the anticipated loads.

The reaction of water with cement is called hydration. The water to cement ratio is an important factor in the ultimate strength of the concrete and its subsequent load carrying ability. The lower this ratio is, the tighter the microscopic crystals of concrete, and the stronger the concrete will be. Fewer shrinkage cracks from excess water will also result from this low ratio.

For a given amount of cement, a smaller quantity of water will produce a higher strength concrete. Too small a quantity of water, however, will not allow for adequate mixing of the sand and stone, and will also make the concrete difficult to "work" and to form, which in turn will produce a lower strength concrete.

The amount of water in a particular concrete mixture is thus carefully selected to balance the desired strength of the concrete. Whether a "soupy" mix, or "firm" mix, the ability of the concrete to be shaped, worked, and placed is called fluidity. The slump test is a quality control measure of the fluidity of the concrete mixture.

The procedure for the slump test is covered in ASTM (American Society for Testing & Materials) Document C-143 from a sample of concrete obtained per ASTM C-172. The slump is measured in inches. The measured slump is then compared to the desired specifications.

The equipment for the slump test is usually a metal cone, a metal base plate and a metal rod. The "cone" is 12 inches in height, 4 inches in diameter at the top, and 8 inches in diameter at the bottom. The slump test must be performed within 2 1/2 minutes after obtaining the sample.

1: The cone, base plate, and rod are moistened with water.

2: The cone is placed on the base plate with the 8" opening at the bottom.

3: The cone is filled in three (3) equal layers.

4: Each layer is rodded 25 times to settle the concrete, before the next layer is added.

5: The cone is then pulled straight up and off of the sample. The cone must come off within

3-7 seconds for an accurate test, per ASTM standards.

6: When the cone is removed, the concrete mixture "slumps" down. It is then measured to determine how far down it has slumped, and compared to specification.

Page 39

03/10 39 50614 Rev. 5

The slump test is a direct measure of the amount of water in the mixture, unless ADMIXTURES are added. Admixtures are liquid chemicals added to concrete to make it easier to place without the reduction in strength adding water would cause. Admixtures of this type are known as "plasticizers" or "water reducers", and adding them to the mixture will either make the concrete mix more "plastic" with the same amount of water, or allow the concrete to have the same "plasticity" with a smaller amount of water (increasing strength). Testing and ensuring the slump specification for concrete is correct will enable the concrete mixture to have the strength and placability the designer requires it to have.

APPENDIX IX: About the AAR:

The Association of American Railroads (AAR) is one of the nation's oldest and most respected trade associations and represents the major freight railroads in the United States, Canada and Mexico. Amtrak and some commuter railroads are also members of the AAR. In addition, the AAR has two categories of associate members, one for smaller railroads and a second for railway suppliers and others with an interest in railroads. The AAR serves as the joint representative of its individual members in matters requiring cooperative handling to better enable railroads to be an efficient, safe, inter-linked system. It is governed by a board of directors that includes the CEO of each Class I railroad in the United States. Amtrak, smaller railroads, Mexican railroads and the Railway Association of Canada are also represented on the AAR Board. One CEO serves as AAR Chairman for a one-year term which rotates among the Class I railroads.

About AREMA

The American Railway Engineering and Maintenance-of-Way Association (AREMA) was formed on October 1, 1997, as the result of a merger of three engineering support associations, namely the American Railway Bridge and Building Association, the American Railway Engineering Association and the Roadmasters and Maintenance of Way Association, along with functions of the Communications and Signal Division of the Association of American Railroads. The rich history of the predecessor organizations, each having over 100 years of service to the rail industry, is the legacy of AREMA.

About the American Railway Engineering Association

At the suggestion of Railway Age magazine, a meeting was held in Chicago on October 21, 1898, to organize a forum for the development and study of recommended practices for the newly-integrated standard-gauge North American railway network. This led to a meeting in 1899 in Buffalo, New York, to adopt a constitution and establish a permanent organization named the American Railway Engineering Association (AREA). From its inception, the AREA dealt with the many engineering challenges through standing technical committees. Five of those committees; ties, rail, track, buildings and yards & terminals continued intact continuously from 1899 until the merger and still continue under AREMA functional groups. In 1905, AREA issued its first Manual of Recommended Practices. Its name was changed to the Manual of Railway Engineering in 1970 and is updated annually by the technical committees. The manual, which is now also available on CD-ROM, will continue under AREMA.
