5 basic problems that railway signalling aims to manage

• Space between trains to avoid rear end collision

• Protection at point of convergence

• Road that cross track at same level

• Two way traffic on a single track

• Derailment due to excessive speed

One of the non-safety functions of a Signalling System is to to provide data on train running for passenger information purposes.

• True

• False

In the early days of railways, the easiest way to increase the train driver's stopping distance was to impose time intervals between trains with 20 minutes headway.

• True

• False

A CBTC system is a “continuous, automatic train control system utilizing high-resolution train location determination, independent of track circuits; continuous, high-capacity, bidirectional train-to-wayside data communications; and train borne and wayside processors capable of implementing Automatic Train Protection (ATP) functions, as well as optional Automatic Train Operation (ATO) and Automatic Train Supervision (ATS) functions.”, as defined in the IEEE 1474 standard.

• True

• False

An interlocking is an arrangement of signal apparatus that prevent conflicting movement through an arrangement of tracks such as junction or crossing.

• True

• False

Computer Based Interlocking (CBI) is not suited for modern day traffic requirements. CBI occupying large space to accommodate large number of relays. Sometimes modifications to the system requiring relocation of CBI Room.

• True

• False

Type of Emergency Stop Device (ESD)

• Passenger Emergency Stop Button - PESB

• Point Position Indicator - PPI

• Platform Intrusion Emergency Stop - PIES

• Wireless Radio Unit - WRU

Transponder typically needs no power source. In response to radio frequency energy broadcast by a Transmission Module mounted under a passing train.

• True

• False

Proximity sensor is used to stop the train at the designated point in the station.

• True

• False
