Travel Reference
In-Depth Information
trainset:
A train that functions as a complete unit over a long
period of time. Typically, it has a set number of cars with a loco-
motive (or “power unit”) at each end, making it unnecessary to
“turn the train” at the end of each run.
trolley:
The overhead wire that provides electric power for rail-
roads and transit systems. This term is commonly used when
speaking of light rail systems such as urban trolley cars, while the
term
catenary
is used in connection with intercity trains.
truck:
The entire wheel assembly at each end of a railcar: wheels,
axles, bearings, brakes, suspension, and frame.
trunk line:
Much more than a
spur
, this refers to a rail line that can
extend over many miles.
turntable:
This is literally a lazy Susan for trains. Turntables are
used to swivel locomotives in any number of directions and route
them down different tracks.
unit train:
A freight train that carries only one commodity—coal,
for example.
vestibule:
The drafty, noisy enclosed area you pass through when
moving from one passenger car to another.
Viewliner:
Amtrak sleeping cars used on most of the overnight
trains in the eastern part of the country. Viewliners are easily
spotted because they have a second tier of windows designed to
provide more light in the bedrooms and nighttime viewing for
passengers in upper berths.
