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? Rail crews in charge of loading and unloading must be trained as for they can understand wagon information Example of instruction in AMDS France
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 with headlights and audible devices such as a siren, and both the lights and siren must be activated before moving the locomotive Reflective paint and headlights on a rail vehicle at ArcelorMittal Ostrava (Czech Republic)

Locomotives –TechnologyExamples Diesel-mechanical locomotive Diesel-electric locomotive
Locomotives-Sander boxExamples Locomotives always carry sand to assist adhesion in bad rail conditions.
Brakes control lever Exhaust triple valve MainRéservoir AuxiliaryReservoirs Exhaust Locomotives – Air BrakesExamples Basics Most 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. triple valve

Release Application Running Neutral/Lap Locomotives – Air Brakes 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.
Locomotives – Air Brakes Driver's Brake Valve Running 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.
Locomotives – Air Brakes Driver's Brake Valve "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
Locomotives – Air Brakes Driver's Brake Valve Application "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 .
