The Bukit Panjang LRT Line is a 7.8 kilometres (4.8 mi) light rail line opened on 6 November 1999 as part of Singapore's LRT system. It is fully automated, and the project was contracted to Adtranz, Keppel Corporation and Gammon Construction. The line uses Innovia APM 100 rolling stock supplied by Adtranz (now Bombardier). A complete loop journey on the line (excluding Ten Mile Junction LRT station) takes 28 minutes.

Services

There are three services on the line: A and B terminate at Choa Chu Kang, and C ends at Ten Mile Junction.

Service	Terminal	via	Notes
A	Choa Chu Kang	Senja	Senja to Petir clockwise
B	Choa Chu Kang	Petir	Petir to Senja counter-clockwise
C	Ten Mile Junction	Senja	Operates every 20 Minutes. Loops clockwise via Senja to Petir

Stations

All stations, except Choa Chu Kang and Ten Mile Junction, have two facing side platforms. Choa Chu Kang has an island platform, similar to most Singapore MRT stations, while Ten Mile Junction has only a single platform and is the only station with platform screen doors (supplied by Horton Automatics). Bukit Panjang and Choa Chu Kang have half-height platform doors. Choa Chu Kang station will have two additional platforms and a new set of fare gates to ease crowding during peak hours.

Rolling Stock

The line uses Bombardier Innovia APM 100 "people-movers", similar to the ones used by the Changi Airport Skytrain until 2006, coded C801 and C801A. C801s have been in operation ever since the start of service on the line in 1999, while C801As were delivered and started operations in late 2014. Each unit is 12,800 millimetres (41 ft 11.9 in) long.

Train Formation

As of 2015, the majority of trains are in two-car (M-M) formations. Two-car formations are no longer limited to peak hours only and are now used at all times. This is due to the increase in ridership and the large number of apartments around Bukit Panjang. The units are limited to a two-car train formation because of station length.

Coupling is usually done in Ten Mile Junction Depot and the trains are coupled with the same car type: C801+C801 or C801A+C801A. Occasionally units are mixed for reasons such as breakdowns or testing.

Train Control

The line is equipped with Bombardier’s CITYFLO 550 fixed block signalling system for Automatic train control (ATC) under Automatic train operation (ATO) GoA 4 (UTO).^[1] The subsystems consist of Automatic train protection (ATP) to govern train speed, Automatic Train Supervision (ATS) to track and schedule trains, and a computer-based interlocking (CBI) system that prevents incorrect signal and track points settings.

Accidents

On the morning of November 19 2000, car 111 collided with 117, marking the first and only LRT accident involving head-to-tail collision. The Train Controller initially had to attend to a train unable to depart from the depot. Operation control then received an alarm noting that 117 was missing from Phoenix LRT Station. The track circuit did not detect the train and the cause remains unknown to this day. The Train Controller ignored the alarm and allowed 111 to depart for Phoenix while 117 was still there. The trains collided at a speed of 16 kilometres per hour (10 mph), injuring five passengers.^[2]
