AAR S-374 Type Stainless Steel Badge Plates

Cardwell Westinghouse can laser etch customer brake rigging schematics from supplied .DXF type files onto AAR S-734 type stainless steel badge plates.

• Cardwell’s laser etching machine draws the carbon in the metal plate to the surface leaving a dark brown black etched impression and does not use paint, which can wear away over time
• Ability to easily clean dirt and grit from the stainless steel plate

Air Dryer Reconditioning / Overhaul

The Component Business Unit undertakes the overhaul of Graham-White 975 and Graham-White 994 Air Dryer series twin tower air dryers and Wabtec “Vaporid” Train-Line Air Dryers.  Air dryers are dismantled and all parts cleaned and tested in accordance with the manufacturer’s instructions. The desiccant is replaced with new, along with all seals, Gaskets, O-rings and the recommended mandatory change parts.
 
Prior to dispatch, all air dryers undergo a thorough testing, including 1,000 volt AC HIPOT insulation test, circuit board testing (including memory function), pressure switch testing, air flow performance test and air humidity testing.
 
The overhauled air dryer is securely packed and protected and prepared for shipment to the customer.

Bogie / Casting Overhaul

Wabtec Rail undertakes the overhaul, refurbishment and conversion of all types of locomotive, passenger rolling stock and freight wagon bogies. We are able to offer our customers a fully comprehensive service with the overhaul of the wheelsets, brake equipment, suspension systems and dampers undertaken in-house at our works. We are able to undertake the repair of damaged and fractured bogie frames. Our workshops are fully equipped for carrying out shot blasting, non-destructive testing and repainting of bogies.
 
We provide all accepts a refurbishment service, and currently overhaul, diesel multiple units, electric multiple units, passenger and freight bogies.  The dirty bogies are collected from the customers premise and on receipt at our state of the art workshops, the bogies are cleaned and then components are removed for overhaul. The bogie frames are then shot blasted and undergo examinations, including magnetic particle inspection of key and known and defect areas. The equipment that has been removed is overhauled on our line side production cells, the specialized components, including wheelsets and braking equipment are overhauled in specific production silo. Once the component overhaul is complete the bogie frames are painted are then reassembled with the overhauled equipment. Prior to output, the bogie suspension is adjusted, so they can fit straight under a train. The bogies are then returned to the customer and are ready to undertake passenger service. We also offer a 48-hour turn around service, which reduces the need for addition float requirements to support turnaround times. We have the skills base to offer any heavy engineering solutions including non-destructive testing. We have a large and highly trained workforce and invest in apprenticeship training programs to ensure that our skill bases are maintained.

Casting

As a pioneer of shell molding in the United States our casting operation has been recognized by the American Foundry Society and by " Modern Casting Magazine". All castings poured at Graham-Whiteare made using the shell process, also referred to as the Croning process, in which a resin coated sand is either dumped on a heated pattern to produce a mold or blown into a heated core box to produce a core. Shell molding produces castings with excellent surface finish and tighter tolerances than other sand casting processes. In general, dimensional tolerances are held to +/-0.040" for pattern dimensions and +/-0.015" for cored dimensions. The shell mold process is used to cast ten different grades of gray iron, three grades of ductile iron, five grades of brass and bronze alloys, and five grades of aluminum alloys. Casting capabilities allow up to 35 lbs. in non-ferrous alloys and up to 70 lbs. In ferrous alloys.

Cleaning and Diagnostic Service

Corrosion and the hindrance of heat transfer caused by fouling in heat exchangers are the main reasons for an increase in energy, operating and maintenance costs of a generator. That’s why coolers must be inspected, cleaned and tested on a regular basis. Our standard cleaning and diagnostic service includes a hydrostatic test of the coolers in the received condition (to identify any leaks), a general steam cleaning, replacement gaskets when applicable, and a written initial and final test report.  Regardless of initial test results, the water/headers are removed for evaluation. At that point Unifin issues a set of recommendations and work scope.
