Why ELX Empty/Load Equipment?
Most freight cars built today are designed for gross weights of up to 286,000 lbs. Empty
weights can be as low as 41,700 lbs for some aluminum gondola cars, creating a gross
to tare weight ratio of 6.9/1. New AAR S-401 specification mandates require higher
loaded braking ratios of 11% to 14% on all new cars, putting more emphasis on
reducing empty braking ratios to levels that will prevent costly wheel sliding during
normal braking. Studies have shown that wheels are less likely to slide, even on poor or
slippery track, if the empty braking ratios are kept at or below 25% versus the AAR
allowed 32%.

Wabtec’s expanded family of ELX Empty/Load equipment now includes 40% units that
reduce loaded braking ratios by 60% to ensure that empty cars achieve adequate
retardation, while minimizing chances for wheel sliding. Wabtec’s ELX equipment also
offers other advantages stemming from its proportioning of up-side high pressure air.
This virtually eliminates brake cylinder pressure spikes during initial braking, while
reducing reservoir sizes and related weights.

ELX equipment is available in three different configurations for
simple installation on any car, and is compatible with both body
and truck mounted brake equipment. Required brake cylinder
pressure taps can be included as part of the ELX unit, eliminating
separate installation costs.                                     ELX unit with built-in pressure trap.

       ASCTD: 4-PORT DIAGNOSTIC SYSTEM
                                     The Automated Single Car Test Device is the most effective
                                     way of testing air brakes to ensure they are functioning as
                                     designed. Instead of trial and error repair, the ASCTD helps
                                     to identify the root cause of air brake malfunctions and
                                     tests valves in half the time of the industry standard. The
                                     Wabtec ASCTD is also equipped to conduct brake tests
                                     from the end of the car. This helps to lower maintenance
                                     costs by keeping good cars in circulation, fewer cars in
                                     repair, and also helps improve life cycle costs associated
                                     with improper brake applications (wheel damage, excess
                                     brake shoe wear, and other vibration related issues).

              TRAINLINK™ ES END-OF-TRAIN DEVICE
               Wabtec Railway Electronics’ TRAINLINK ES improves braking performance by automatically
               making service brake pipe reductions at the rear of the train. As the locomotive engineer
               begins making the brake pipe reduction, the desired brake pipe pressure is immediately
               transmitted to the TRAINLINK ES. The TRAINLINK ES responds by venting the desired brake
pipe pressure at the rear of the train. The effect is a dramatic improvement in the brake application
response time, while operating entirely transparent to the locomotive engineer.
              1-1/4” Dynaball Angle Cock
              The DYNABALL angle cock features a Teflon-coated ball to provide smooth,
              effortless hand movement. The large rubber seals, which are self-lubricating, self-
              cleaning and self-adjusting, reduce leakage and can be replaced quickly.

              Retaining Valve
              The RX-3 retaining valve controls airflow from the brake cylinder during brake release. For
              retaining brake cylinder air pressure to control train speed during the brake recharging
              process, the valve can be positioned manually to provide three cylinder release modes: full
              release at either normal or slow air flow rates, or retention of 20 psi.

              Composite Retaining Valve
              The Composite Retaining Valve is an AAR S-446 compliant, lighter version of the current
brass RX-      RX-3 retaining valve and constructed of high strength, UV stabilized, impact resistant
              thermoplastic resin. The durable lightweight design provides long service life and is
              interchangeable with the Standard RX-3 Retainer.

                Two-Compartment Reservoir
                A two-compartment reservoir on a freight car is used to store compressed air for
                auxiliary service and emergency brake applications. The fabricated one-piece design
                has two attachment lugs on the auxiliary side and one lug on the emergency side to
                ensure proper application on the freight car.

                1-1/4” Brake Pipe End Cock
                The 1-1/4” brake pipe end cock is designed for use on specific rail vehicles where the
               standard pipe angle cock cannot be used, and where the air pressure and the
               equipment arrangement does not exceed 150 psi. The cock provides a means for the
               manual closing of the brake pipe, as on the end of the last car of a train consist, and the
 continuation of the brake pipe between coupled cars by the connection of an attached brake hose
 assembly.

                Hose and Coupling
                Wabtec provides AAR compliant End of car Hoses, Brake Cylinder Hoses and Empty
                Load Hoses.

This combination of components guides the
brake beam in a horizontal configuration,
regardless of brake beam end extension wear.
The brake beam is prevented from drooping,
which can cause the top of the brake shoe to
wear more than the bottom as the top of the
brake head tilts closer to the wheel tread. It
also reduces the frictional losses between the
brake beam and the side frame pocket,
thereby increasing the rigging efficiency and
reducing brake shoe force variations from side
to side on the same brake beam.

                                         S2HD-9C Design
                              The S2HD is the first true 100 ton three-piece freight car truck, and has
                              been used extensively in heavy axle load service for over thirty years.
                              So, when it came time to arrange the secondary suspension spring group
                              for the S2HD-9C for S-286 service, we decided to go with the proven, full
1.5 reserve ratio, 286K GRL capacity spring group for the truck. As designed, the S2HD-9C offers a
substantial load carrying capacity advantage over an alternative truck, which has only 5 inner load springs
making it essentially a 263K GRL capacity suspension. The S2HD-9C is also M-976 approved for use on all
110 ton cars.

The primary suspension and snubbing components are also featured here to further emphasize the
importance of the three component groups together. As illustrated here, the primary suspension is made
up of a roller bearing adapter and shear pad, and the snubbing is made up of the wedge, pocket insert,
sidewall wear plate, and column wear plate. More detail is provided about these components later in the
booklet.


Our S2HD-9C is M-976 approved for use on all 110-ton cars and offers
a substantial load carrying advantage compared to alternative trucks.
                                                                                                          41



                                    Split Wedge Design
                                             Bolster Pocket Insert




                                                    Side Wall Wear Plate




               The Bolster Pocket Inserts and Side Wall Wear Plates
                are easily replaced within minimal time and effort.

The S2HD-9C also includes the modern standard of wedge performance, the split wedge. Developed
in the ’90’s to improve stability and curving, the split wedge accomplished both and has become the
preferred wedge of many railroads and car owners alike.

Our 915-SW Split Wedge features easy to install and replace bolster pocket inserts and sidewall wear
plates. We include these durable, labor saving components in all our S2HD bolster castings standard
to ensure that every Standard Car Truck Barber truck exceeds your life cycle expectations, and is easy
to restore to new condition with a minimum of time and effort. Instead of time consuming and
difficult weld and grind, our pockets are restored by simply replacing the inserts and sidewall wear
plates.

Our 915 friction castings are made of highly durable friction iron, instead of steel. Our friction iron
has proven to be more than twice as durable as steel, creating better longer lasting friction castings.
Our friction iron has also proven to have lower friction than steel, creating a smoother acting, better
performing friction wedge.




             The Modern Standard of Wedge Performance
                                                                                                                    42



                           One-Piece Wedge vs. Split Wedge




   Example of a One-Piece Wedge. The gaps (shown by the green arrows) allow movement resulting in wear to the truck.

Why are split wedges better? They are because they do a better job of keeping the truck square, and a
square truck is a better performing, and longer lasting truck.
One-piece wedges leave gaps between the wedge and sidewalls in order to provide space to fit the wedge
into the pocket. After installation, these gaps are undesirable, because they leave room for the wedge to
move in the pocket. So, the one-piece wedges rotate easily allowing the truck to warp. Truck warp then
leads to more wheel wear in curves, and component wear and damage from hunting.


       Split Wedge =A better performing, longer lasting truck




      The Split Wedge design eliminates the gap problem, thereby eliminating truck warp caused by wedge rotation.


The split wedge solves the gapping problem by bracing two independent wedge halves against the
sidewalls. The split wedge bracing action eliminates the possibility of truck warp due to wedge rotation,
and raises truck squaring or warp resistance to a much higher level. With the split wedge, a truck cannot
warp unless the wedge halves slide in opposite directions to each other, and this action requires much more
warp force. As a result, the 915-SW Split Wedge keeps the truck square at higher speeds, under greater
loads, in tighter curves, and for more of its life than any one-piece wedge can.

                             S2-86 Radial Adapter
The Barber S2-86 Radial Adapter is based on time tested technology that has been in service for
many years and many heavy axle load gross ton miles. The name, as you might have guessed, is a
conjunction of our well known Barber S2 truck brand name, including S2-A, S2-B, S2-C, and S2-HD,
and the AAR’s S-286 rule which governs cars in the weight category for which the adapter is
approved. And, the Radial part of the name is meant to convey the semi-radial steering
performance that the shear pad is designed to provide, as well as echo our long history in high
performance truck design by recalling to mind trucks like our Barber Radial.

The adapter is essentially a trim version of the AAR standard narrow pedestal adapter. And, the
primary suspension element is a trim one layer version of our successful, million mile two layer
shimmed shear pad.




             Double Side Tabs act as rejection lugs for
            the old style lord pad and differentiate the
             S2-86 from the standard adapter which
                        has Single Side Tabs.

                                Features & Benefits:
•Center recess – acts as a wear gauge and like the standard adapter, provides better
load distribution for pedestal inconsistencies.
•M-924 approved – Roller Bearing Adapter Specification – Gauge Related
•Shear pad thickness just under the current Pennsy Adapter Plus.
•Vulcanized rubber bonded to steel. Very durable with wide operating temperature
range.
•Center rejection lug – pad cannot be used on std adapter
•Ground wire – static discharge

Barber Brake Beam, Diagonally Corrected End




      Another innovative and cost saving feature available from Barber Brake Beam is the
     diagonally corrected end. Conventional brake beam ends, like the one shown in the first frame
     are designed as though brake beam forces were balanced, but they’re not. Unbalanced forces
     on conventional brake ends allow the brake beam to rotate in the guide pocket, and wear out
     brake shoes at the top end. The Barber diagonally corrected end, counteracts brake beam
     rotation, and provides even pressure across the full face of the shoe.

Brake Rod Wear Protector

Brake Rod Wear Protectors are welded directly to the brake rod to prevent metal-to-metal contact
and subsequent wear between brake rods, hangers, axles, and truck bolsters. Fits ¾” to 1” diameter
rods.

 • Applied by method of Longitudinal Stitch Weld, preferred by AAR over the Transverse
 Welds on the “Horse Shoe” stops used with the slotted tube application.

 • Provides a flat 1 5/16” bearing surface that lasts the life of the car. (The “Point Contact”
 of the slotted tube application can wear quickly, especially on top of the rough bolster

Glossary of Terms
COLD FLOW
Cold Flow, otherwise referred to as creep, is the dimensional change over time of a material under a
physical load. All materials cold flow, to varying degrees, when a load is applied. After the load is removed,
Memory, it the ability to return to its original dimensions while Compression Set takes place when the
material does not return to its original state. Material wear, or loss of material, must not be confused with
Cold Flow. A product will weigh less after it wears but will weigh the same after it Cold Flows, or simply
changes its shape. A typical value for comparing materials is given in pounds per square inch or p.s.i.
Therefore, the higher the PSI rating the more Cold Flow Resistant the material is. Material characteristics
will vary with time, temperature, rate of loading, part density and wall thickness.


COEFFICIENT OF FRICTION
Coefficient of Friction, or C.O.F., is a value (number) used to compare how hard or easy two materials will
slide against each other. Lubricated or greased “Steel-on-Steel” is around 0.1 while dry, or un-lubricated,
“Steel-on-Steel” can be 0.5 to 0.8 or higher. There are many factors that will effect the C.O.F. between two
surfaces. Some of these are of course lubrication, surface texture, material hardness, and the material itself.
Generally speaking, constant lubrication is required to maintain low frictional properties. However, some
plastics or polymers, like Nylon or UHMWPE, have a very low C.O.F. against a smooth steel surface even
without any lubrication. Other polymers, like a soft urethane, can have a very high C.O.F. unless lubricated.


MOLECULAR WEIGHT
Technically, the Molecular Weight is the average weight of a molecule in a material. It is actually the “sum of
atomic weights of all the atoms in that molecule”. In laymans terms, the higher the Molecular Weight – the
longer the molecular chains, and therefore the denser the material. For instance Nylons and Polyethylenes
can be processed into various molecular weights – less than 50,000 (low) – 50 to 100,000 (medium) –
100,000 to 2 million (high) – 2 to 3 million (very high) – and 3 to 6 million (ultra high). For instance the
lowest polyethylene products range from candle wax and shrink film, to the medium and high densities of
bottles and toys, to the ultimate Ultra High Molecular Weight Polyethylene, or UHMWPE.
