The Hinkle locomotive service and repair facility is strategically located on Union Pacific Railroad's busy Pacific Northwest corridor.
Construction of the $32 million facility began in October 1996 and was completed in October 1998. Despite construction taking place adjacent to an active work area, no personal injuries occurred during construction.
The facility is designed to serve the locomotive service and repair needs of Union Pacific's PNW corridor well into the future.
The 100,000-square-foot repair facility is comprised of several buildings, with offices, a warehouse, a parts-storage area, locker rooms, mechanical systems, an automated locomotive wash area, and four run-through tracks for repairing 12 locomotives at one time. The main building is 302 feet long and 226 feet wide.
There are two 340-foot service tracks outside the building, capable of handling ten locomotives at a time, five on each track.
In addition to scheduled maintenance, this facility handles running repairs; including changeouts of power assemblies, traction motors, alternators, air compressors, turbos, engine-blowers and electrical components.
The repair area has eight cranes (one 10-ton crane, one 15-ton crane, and six 3-ton cranes) over the run-through tracks for replacing locomotive components. Service pits run the entire length of the shop to provide access underneath locomotives.
The repair area equipment also includes a wheel true machine, a drop table and a shim table, a high volume parts washer and 18 hose reel supply stations. Also located in the repair area are an oil laboratory, a resource center and an accident repair area.
The service tracks have counterbalanced fueling arms, an overhead sand gantry system, a central toilet servicing system, two service pits, a light repair pit, a turntable, and ready tracks.
Hinkle is the only major locomotive repair facility on the Union Pacific Railroad to incorporate a zero-discharge system for sanitary and industrial waste streams.
Industrial wastes are treated in the new wastewater treatment facility and then discharged to a series of aeration ponds. Sanitary wastes are discharged to a separate oxidation pond. The drip pans used to capture oil leakage from locomotives at the service track and repair facilities are equipped for secondary containment.
More than 235 employees at the Hinkle locomotive service and repair facility support the 24-hour-a-day, seven-day-a-week operation, completing extensive inspections on an average of six locomotives a week.
The service track fuels and readies nearly 90 locomotives a day, and the 3.5 million gallons of diesel fuel used monthly at the service area is expected to steadily increase.
