UNION PACIFIC GOES FOR THE "4-RUNNER"

UP and Trailer Train are committed to the production of 100 four-unit intermodal flat cars, each unit of which has a pair of single-axle trucks. Weight savings and improved aerodynamics are achieved, along with the ability to move the increasingly popular 45-ft trailers. The four-wheel units represent a combination of American and European technologies. Four-unit cars are assembled by intermediate hammerhead drawbars; outer ends have conventional couplers and draft gears. Standard components have been used wherever possible. UP will assemble its 191-ft cars in trains for Chicago--Los Angeles intermodal service.
