The Bukit Panjang LRT Line is a 7.8 km light rail line opened on 6 November 1999 and 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 the Bombardier Innovia APM 100 rolling stock supplied by then Adtranz, now Bombardier, and is similar to the ones used in the Changi Airport Skytrain service during until 2006. A complete loop journey on the line (excluding Ten Mile Junction LRT station) takes 28 minutes and all stations, except Choa Chu Kang and Ten Mile Junction have two opposing side platforms, like Dover, Braddell MRT stations and Fernvale LRT station. Choa Chu Kang LRT Station has an island platform layout like most MRT stations but Ten Mile Junction Station only has a single platform and the only station with platform screen doors. Both Bukit Panjang and Choa Chu Kang stations are the only stations with half-height platform screen doors.Choa Chu Kang station will have 2 additional platforms and a set of new fare gates to ease the crowding during peak hours.

Coupling is usually done in Ten Mile Junction depot and the trains are coupled with the same car type, example, C801-C801, or C801A-C801A. But sometimes the trains are coupled differently due to reasons like breakdowns or testing.

As of 2015, the majority of Bombardier Innovia APM 100 trains are in two-car formations. Two-car formations are no longer operating during peak hours only and are now being converted to full-day operation including off-peak, public holidays and weekends. This is due to the high number of apartments around Bukit Panjang and the increase in ridership.

History

In the morning of November 19 2000, train 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 not being able to depart from the depot. Then operation control receives an alarm noting that train 117 was missing from Phoenix LRT Station. The Track Circuit could not detect the train and till this day the reason is unidentified. The Train Controller ignored the alarm and allowed train 111 to depart for Phoenix station while 117 was still there, thus allowing this incident to happen. Train 111 collided with train 117 at the speed of 16km/h, injuring 5 passengers.

Plans by the Land Transport Authority have indicated a Mass Rapid Transit station (Bukit Panjang MRT station) near Bukit Panjang LRT station as part of the Downtown Line, which is expected to open in December 2015. It was revealed by the authorities in 2009 that the existing bus interchange could be moved closer to the upcoming MRT station. Previously, the LTA had explained that the MRT station could not be moved next to the LRT station owing to technical constraints. Residents had pointed out that transfers would be inconvenient as the MRT station will be sited about 120m from the existing Bukit Panjang LRT and bus interchange.^[1]

Rolling Stock

Trains operating on the Bukit Panjang LRT Line are the Bombardier Innovia APM 100 "people-movers" coded C801 and C801A. C801 trains have been in operation ever since the start of service on the line in 1999, and C801A trains were delivered and started operations in late 2014. The trains, however, only have the ability to be coupled into a 2-car train formation due to station length.

Train Formation

The configuration of a C801/C801A in revenue service is M in single car mode and M-M is dual car mode

Train Control

The Bukit Panjang LRT Line is equipped with Bombardier CITYFLO 550 fixed block signalling system with Automatic train control (ATC) under Automatic train operation (ATO) GoA 4 (UTO).^[2] 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 to be set.

At the Station, Ten Mile Junction was equipped with Platform screen doors which was supplied by Horton Automatics which also can be found on Toulouse Metro and Turin Metro and it is only station which supplied by Hortom Automatics which was supplied by Adtranz (now Bombardier Transportation).
