| These 4180
cu. ft. Airslide hoppers with Barber Roller Bearing trucks were
built in 1973. With a special epoxy lining, these cars were specifically
designed for use with fine-grained commodities, like powdered sugar,
that could settle en-route making unloading difficult. Union Pacific
is now exclusively a freight railroad with over 32,000 miles of
track, but prior to 1971, UP also operated numerous passenger trains
and services. |
