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

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

Locomotives – Air Brakes
Examples
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.

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.
Release
Application
Running
Neutral/Lap
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.
11
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.
12
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
13
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 .
