250 terms in this trade.

air line

A railroad following a very flat, straight route between two endpoints in order to minimize travel times, choosing the shortest, most direct route practical even if longer route that was more advantageous was available.

aspect

The visual indication of railway signal as displayed to the driver. With three-aspect colour light signals this would be red, yellow or green, and on four-aspect signals, double-yellow also; a two-aspect signal displays red or green.

autoballaster

A type of ballast wagon, used to carry new ballast and then spread it along a section of railway track.

autocoach

An unpowered railway coach with a driving cab at one end, used in a push-pull train in conjunction with a locomotive or other powered vehicle.

automatic train control

A train protection system that involves a speed control mechanism in response to external inputs. For example, a system could effect an emergency brake application if the driver does not react to a signal at danger.

axle guard

The part of the framing of a railway car or truck by which an axle box is held laterally, and in which it may move vertically.

axle load

the total weight, including load carried, transferred by one axle and its wheels to a road or railway surface. This is especially important in relation to what weight road and railway structures can carry, bridges in particular.

baggage car

A railway vehicle in passenger trains used to carry passengers' heavy luggage; a luggage van.

banner repeater

A type of railway signal which shows the aspect of a signal ahead of it, normally used in a situation where the main signal is hidden from view, for instance where there is a curve in the track.

bar car

A railroad passenger car where drinks are served, typically with seating arranged around cocktail tables.

barrow crossing

A type of crossing found mainly in railway stations which allows passengers to cross between platforms at track level.

blind spot

The part of the railway/tramway track that cannot be seen in the side mirror or the side window.

block section

In railway signalling, a section of track on which, in normal circumstances, only one train is allowed at one time.

block system

On railways, a system by which the track is divided into sections of three or four miles, and trains are run by the guidance of electric signals so that no train enters a section or block before the preceding train has left it.

bogie bolster wagon

A long flat wagon mounted on two four-wheel bogies, with transverse baulks of timber (bolsters) placed at intervals on the wagon's bed to carry the load.

brake van

A railway vehicle used to brake a (goods) train, usually placed at the end of the train. These were essential before continuous train braking became universal.

break of gauge

an occurrence where a railway with one track gauge meets another railway of a different gauge, thus requiring transhipment of goods and passengers, or a change of bogies on the train.

buffer up

To move (a rail vehicle) so that its buffers are touching the buffers of another rail vehicle.

buffet car

A railway carriage in which food and drink can be bought at a counter, and either taken to another carriage or consumed at the seating provided.

bullhead rail

A type of rail, most commonly used in the United Kingdom (now obsolescent), with a head and foot similar in cross-section, that is supported in cast-iron chairs and secured in the chairs by wooden wedges (known as "keys") or steel springs.

cab forward

a design of steam locomotive with the cab at the front, mainly built for the Southern Pacific Railroad, which at one time had a large fleet of oil-fired articulated locomotives.

cab signalling

A rail safety system installed in the driving cab of a train, which gives information to the train driver on track status and condition.

car

Any vehicle designed to run on rails, especially an unpowered one towed by being connected to others.

car mile

A mile travelled by a single railway car, taken as a unit of computation, as in computing the average travel of each car of a system during a given period.

car shed

A large building provided for the housing and maintenance of passenger cars or carriages (or coupled trains thereof).

cattle wagon

a covered or uncovered goods wagon (mostly formerly) used for the transportation of live cattle.

centralised traffic control

A form of railway signalling that does away with intermediate signallers over a long stretch of track, often single track with loops where trains can pass each other, by remote control from one location.

chair

A cast-iron component used on railways to support bullhead rails and secure them to the sleepers.

chair car

A railway car equipped with reclining armchairs, for passengers travelling at night who do not wish to ride in a sleeping car.

check rail

A rail laid parallel to a running rail to guide wheels through points, rail crossings, and round curves, to reduce wear and the risk of derailments such as those due to flange climb.

club car

A railroad car that serves in the manner of a club (lounge), offering drinks, snacks, background music, and sometimes meals.

coach

A passenger car, either drawn by a locomotive or part of a multiple unit.

coaching stock

passenger-carrying railway coaches or (less commonly) multiple units. Contrasted with locomotives, freight wagons and engineering vehicles.

colour light signal

An electric railway signal with colour aspects, showing either red or green in a 2-aspect signal, with the addition of a yellow or double yellow aspect (meaning caution) in 3- and 4-aspect signals.

combination car

A railroad car containing two or more compartments used for different purposes, transporting passengers and freight.

commuter rail

A rail transport system with trains used to transport commuters between two places, typically their homes and works, normally within a metropolitan area and its surrounding environs, and generally distinguished from other rail transport systems (i.e. subways, metros, tramways) by having less frequent service, lacking free transfers between trains and using heavy rolling stock running on a mainline railway
