Track layout

Conductor rail.

Sits raised above the sleepers on insulating pots

Track layout- on or near the line

“On or near the line”

Within three meters of the line.

The line it's self

Track layout

Stopping a train in an emergency. How?

To stop a train in an emergency:

Both hands above head

Hold a red flag steady

Red light (torch)

Any other colour light waved vigorously

ECO

The Electrical control operator (ECO) is in charge of track power supply

Conductor rail voltage

CONDUCTOR RAIL

750-850V Direct Current (DC)

PTS

PTS is required if working on or near the line within 3 meters or if carrying out technical work 1.25 meters from the rail on a platform

Conductor rail safety

You must be no closer than 1.5 meters. Safe minimum distance for the Conductor rail is 1.5 meters.

This includes anything you are holding

AC line voltage

AC runs at 25,000V, or 25KV.

Where is AC power drawn from

Power is drawn from over head wires. The Electrical control operator has the ability to isolate power in an emergency

OLE

Equipment is referred to as overhead lines equipment (OLE)

AC lines equipment- how to identify a structure

There is a STRUCTURE PLATE to identify each part of overhead lines equipment (OLE)

AC line safety distance

Any live equipment must maintain a safe distance of at least 2.75 meters

AC line safety considerations

A safe distance of 2.75 meters must be maintained from all OLE including:

Anything hanging in contact with OLE

Anything live, or potentially live

any broken piece of OLE that is still in connected and may be live

This includes staying at least 2.75 meters from anything connected to OLE including the train pantograph

CANT line

The CANT line is an orange line on trains showing the maximum safe height near the train

BOND wires

Bond wires- act as earthing equipment for OLE. Carry high voltage

Sectional appendix

The sectional appendix is a map. Islt shows the speeds and directions of travel

Sectional appendix terms

Up line: Usually London. Specified in the sectional appendix and shows the destination in a specified location.

Down line: train travelling away from a specified location. Usually away from London

Bi-directional line: trains cancelled travel in either direction in an environment where there is more than one line

Single line: a single line where trains can travel in either direction

London end: closer to London

Country end: location furthest from London

London side: a side of a structure closest to London

Country side: a side of a structure closer to the country

Telephones- emergency phone

Emergency phone- GREEN

Contains numbers, OS grid reference and ectrical control operator phone numbers

Telephones- non emergency

Standard auto dial- contains electrical control operator

Telephones- line side

Line side Phone: direct to signaller located at all strategic locations

a box with an x on the front

Telephones- signal post

Signal post: direct to signaller always associated with a nearby signal box with black stripes like a zebra

Telephones- level crossing

Automatic level crossing: direct to signaller located at crossings box with a yellow phone

Operational railway requirements

You need:

A good reason to be on or near the line

Orange high visibility clothing

To be trained and certified as competent

Personal track safety certificate

Safety footwear

Hand lamp during poor visibility

To have route knowledge

Railway environment

On or near the line- within 3 m of the line,

on the line itself

or when you're doing technical work in 1.25 m of the line on a station platform

Position of safety definition

Defined as safe distance from running rail or conductor rail

Position of safety relative to line speed

Up to 100 miles per hour- 1.25 m

100 mph to 125 miles an hour- 2 m

Or 1.5M away from the conductor rail if on side nearest to you

Authorised walking route, use, location of information and reporting procedures

Takes you to or from a place of work

Details of authorised walking routes are displayed locally in depot or station

Defects reported to local managers (usually DM’s)

While walking precautions

Use walking routes were provided

If in cess, face oncoming traffic

do not wear anything that makes you less visible

Carry objects correctly, making sure they do not make contact with rails

Do not become distracted

Do not use headphones or wear anything that may obscure your view and hearing

Ensure nothing is hanging loose

Keep a good look out for trains

Limited clearance sign (white, red, red, white)

Located on a structure indicates there is no position of safety on this side of the railway for the length of the structure

Must not enter or stand a location while a train is approaching

No refuges sign (white, blue, blue, white)

On this side of the length of the structure there are no refuges cross over to the side with refuges

never walk here

Restricted access phone

Indicated with a diamond with an X or a yellow roundel

This phone is associated with a signal and for emergencies only

Crossing a line

The safest way is to use a footbridge or Subway

If not available, find a gap in the conductor rails
