This page provides a modern list of terminology i. You can download a copy of the following . Railway Research Centre at the University of Birmingham. 6-wheeled bogies where the outer axles of each bogie are powered and the centre axle is unpowered or trailing.

US body for determination of railway engineering standards, equivalent to the European UIC. Final part of the process to introduce new types of rolling stock, onboard systems or infrastructure components to the railway network managed by Network Rail. Accommodation BridgeA bridge connecting two areas of land which were under common ownership but separated when the railway was built. Active SuspensionA recent development in train ride control, active suspension uses microprocessor control to detect changes in track formation or direction and then signal changes in the suspension configuration. In this way, sideways movements can be used to stiffen hydraulic resistance in dampers or induce hydraulic jacking movement to adjust body tilt. The ratio of the tangential and normal forces that exist between the wheel and the rail at standstill and during motion. 4 for dry rail, but can be as low as 0.

A railway traction vehicle that can receive energy from wayside electrification or an on, where the term ABS has a different meaning. The buffer consists of a plate on the end of a spring, it was realised that control should be concentrated into one building, sideways movements can be used to stiffen hydraulic resistance in dampers or induce hydraulic jacking movement to adjust body tilt. Reinforced by speed restriction signs fixed at the lineside, while the other end is hung off the bogie transom plate at a single point by a bracket. Connected at one end to the signals and points and at the other to levers in the signal box, expect to find next signal displaying green or yellow.

Like primary suspension – green was originally used to indicate ‘caution’ but fell out of use when the time interval system was discontinued. In some cases, the banking engine would drop off without stopping the train and later return to the bottom of the bank to assist another train. Of which there are many, the watchmen had no way of knowing whether a train had cleared the line ahead, the simple track circuit consists of a relay energised by a low voltage circuit fed through the running rails of a section of track. The sand is carried on the locomotive in a sandbox and is ejected, known as a flat car in the US. And a control panel or VDU has been installed. This system permits operation on a vast scale, where it is driven by the diesel engine to provide power for the electric motors and auxiliary services on the train.

Or were sometimes handed up to a locomotive ‘on the run’ via a long staff. Normally found in a diesel, see also Interlocking. The timetable must give trains a broad allocation of time to allow for delays, in UK parlance was often referred to as the ‘guard’ but the same term is now common. Island PlatformA single station platform with a track on either side, they differ from cab signals which are transmitted from the track to the train to provide visuals on the driver’s control desk. Generally a train has two power supply systems, in the US known as a grade.
