Definition and terms

Bogie (UK) – a four or six-wheeled frame, normally used in pairs under long-bodied railway vehicles and on locomotives or individually in-between two sections of an articulated vehicle. The bogie has a central pivot point, which allows it to turn as the track curves and it thus guides the vehicle into the curve.

Rail car (US) - any non-powered rail vehicle

Trolley (UK) – a four wheeled, hand operated works vehicle for transporting staff and tools.Powered Trolley (UK) - a motor-driven works or inspection vehicle

Sleeper (UK) – in the US known as "ties", short for "crossties". The transverse members of track (-work), made of wood, concrete or steel, or even plastic composite, which are used to secure the rails at the correct gauge. Cast steel chairs fixed to the sleepers hold the rails in place by means of clips or keys.

FPA Questions• Level 1 Q 7 Have safety rules been written on the basis of a HIRA for loading and

unloading operations on and from wagons? Do those rules take into account the vehicles gross weight, the necessary load sharing out, wedging and stowing in the wagon?

Example of instruction in AMDS France

Rail crews in charge of loading and unloading must be trained as for they can understand wagon information

FPA Questions

• Level 2 Q 8. Are locomotives fitted with headlights for both directions and audible devices such as a siren? Prior to moving the locomotive, Is the audible alarm sounded and are the headlights tested and then kept on in the direction of movement whilst the locomotive is moving? Is it he audible device used when crossings of roads and pedestrian walkways?

Locomotives must be fitted withheadlights and audible devicessuch as a siren, and both the lightsand siren must be activated beforemoving the locomotive

BasicsMost of the trains are equipped with braking systems which use compressed air as the force to push blocks on to wheels or pads on to discs.  These systems are known as "air brakes" or "pneumatic brakes".  The compressed air is transmitted along the train through a "brake pipe".  Changing the level of air pressure in the pipe causes a change in the state of the brake on each vehicle.  It can apply the brake, release it or hold it "on" after a partial application.

Driver's Brake Valve

Driver's Brake Valve is the means by which the driver controls the brake.  The brake valve will have (at least) the following positions:  "Release", "Running", "Lap" and "Application" .  There may also be a "Shut Down" position, which locks the valve out of use; and an “Emergency” position . Its operation is the same as the "Application" position, except that the opening to atmosphere is larger to give a quicker application.

The "Release" position connects the main reservoir to the brake pipe .  This raises the air pressure in the brake pipe as quickly as possible to get a rapid release after the driver gets the signal to start the train.

13

In the "Running" position, the feed valve is selected.  This allows a slow feed to be maintained into the brake pipe to counteract any small leaks or losses in the brake pipe, connections and hoses.

14

"Lap" is used to shut off the connection between the main reservoir and the brake pipe and to close off the connection to atmosphere after a brake application has been made.  It can only be used to provide a partial application. A partial release is not possible with the common forms of air brake, particularly those used on US freight trains.

Neutral/Lap

"Application" closes off the connection from the main reservoir and opens the brake pipe to atmosphere.  The brake pipe pressure is reduced as air escapes.  The driver (and any observer in the know) can often hear the air escaping .
