Bombardier INNOVIA APM 100 (C801A)

The Bombardier INNOVIA APM 100 (C801A) trains are the second generation of rolling stock for the Bukit Panjang LRT. These are rubber-tyred automated people mover (APM) trains, also referred to as light rail vehicles (LRVs), designed for small-scale automated guideway transit (AGT) systems.

13 train cars were purchased, capable of operating in single and double car formations and have been in passenger service since 19 November 2014.

These trains operate on an exclusive elevated guideway, unhampered by road and pedestrian traffic. Compared to the metal-wheeled MRT trains, these APM trains are fitted with rubber tyres and are relatively quiet during operations.

The smart misting glass windows of these trains are well-known over the Internet, with netizens intrigued by this innovative feature to protect the privacy of residents living adjacent to the LRT line.

Utilising Bombardier's CITYFLO 550 Automatic Train Control (ATC) signalling system, these trains are capable of fully automated operations and can run without any train attendant on board.

These trains are currently undergoing retrofitting works to enable the utilisation of Alstom's Cityflo 650 Communications-Based Train Control (CBTC) signalling system in the future.

Bukit Panjang LRT

13 train cars, numbered 120 to 132

The Bombardier INNOVIA APM 100 (C801A) trains are maintained by SMRT Trains.



Contract 801A to supply new APM trains was awarded by the Land Transport Authority (LTA) to Bombardier Transportation in 2012, after initial plans to increase the line's capacity were announced on 28 July 2011.

13 train cars were purchased for the 7.6-kilometre long Bukit Panjang LRT (BPLRT), increasing the line's capacity by about 50 per cent.

The new trains reduced headways between Choa Chu Kang and Bukit Panjang LRT stations from 2.5 mins to 2.2 mins and from 5.0 mins to 4.4 mins for the loop between Petir and Senja LRT stations during peak hours.

Bearing similarities to the first generation Bombardier INNOVIA APM 100 (C801) trains, the first two C801A trains entered passenger service on 19 November 2014.

Renewal of the Bukit Panjang LRT System

The LTA awarded Alstom Transport (previously known as Bombardier Transportation) the contract to renew the BPLRT system on 7 March 2018.

Contract 801B for asset replacement and reliability enhancement works included retrofitting all 13 second generation C801A train cars to utilise Alstom's Cityflo 650 CBTC signalling system by end-2022.

The first two retrofitted train cars returned to Singapore from New Jersey, America, on 2 April 2021.





The exterior of the train features a mainly white colour scheme, with SMRT's refreshed livery of yellow, red and black.


The seats have a colour scheme of lime green. The reserved seats, catered for commuters with special needs, are differentiated in red.

The train features a viewing space at both ends of the train, serving as additional seating space.

These trains have much wider doors for faster boarding and alighting.

Its spacious interior also allows for a higher passenger capacity.



Smart Misting Windows

The train cars are equipped with smart misting windows (except the front windows).

The windows will mist within 6 metres (20 feet) of residential buildings, eliminating privacy concerns.

Reserved Seats

Reserved seats are differentiated in red, signalling commuters to give these seats to those who need them more.

Viewing Space

Both ends of the train feature a viewing space.

The viewing space allows passengers to view Bukit Panjang through the windscreen.

Overhead Hand Grips

Overhead hand grips are positioned along the aisles of the train cabins to provide standing passengers with increased support.

LED Travel Information Displays

The LED Travel Information Displays provide commuters with their route information throughout their journey.

These are located above every train door.

Builder Plate

The builder plate lists the companies involved in the manufacture of the train, and also the car number.

Emergency Next Station Stop

The Emergency Next Station Stop button, located at the side of the train doors, stops the train at the next station in an emergency.


Intercoms are located at both ends of the train to contact the train staff in an emergency.
