Bombardier Innovia APM 100 C801 (APM 100, originally known as CX-100) is the first generation of an automated people mover (APM) train built by Adtranz (now Bombardier Transportation) for use on the Bukit Panjang LRT (BPLRT).

Operational history[]

The C801 trains have been operating since the BPLRT's opening in 1999. If such plans go through, it will be the first major overhaul for the C801 train cars. The refurbished train cars will have upgraded air-conditioning and air compressors together with an improved braking system plus installing Close Circuit Televisions (CCTV) under each train car to monitor under the train cars. However, plans of replacing the train cars are not ruled out by LTA.

Defects in the C801 rolling stock[]

Minor defects in the C801 rolling stock was made public in a press report made by operator SMRT Trains managing director Lee Ling Wee in 2016, when it was admitted that C801 trains had suffered from cracks.^[4] This was after the cracks from the rolling stock C151A trains, which runs on East West line and North South line, were made public on 5 July 2016 which caused a public uproar (See Operational Problems in C151A). According to the press report, the cracks was discovered "during a routine assessment by Bombardier in 2015" and the issue affected all 19 C801 trains. It was stated that 12 of them have fixed locally using wielding methods with remaining 7 awaiting for repairs as of time the report was published, having suffered the issue to a lesser degree.^[4]

Lee did not reveal what caused the cracks, but a spokesman for Land Transport Authority told Straits Times that the issue is caused by "normal wear and tear" and added that they are not 'safety-critical'. All cracks in C801 trains were found on the "lateral beams of the under-frame" and they measured "no more than 12 cm".^[4]

Replacement[]

On 7 March 2018, the Land Transport Authority awarded the contract for renewing the Bukit Panjang LRT system to Original Equipment Manufacturer (OEM) Bombardier (Singapore) at a cost of $344 million.^[5] Under the contract, all of the 19 C801 trains would be withdrawn from service, and replaced by Bombardier Innovia APM 300 C801B automated people mover cars.^[6]

Exterior design[]

• C801 trains have rectangular, incandescent headlights compared to the C801A trains, which have circular, bright white LED headlights.^{[citation needed]}
• Windscreen and windows are tinted green, while spoilt windows have a different tint.^{[citation needed]}

Interior design[]

The C801 trains are very similar to the C801A trains in terms of interior design, other than the color scheme used.

• All seats of the C801 trains are turquoise, with 4 seats on each end and 8 seats in the middle.^{[citation needed]}
• LCD screens were installed initially, then later taken out of the train. LED screens above the doors display the current and next station information.^{[citation needed]}
• As the carriages are closed-end, for passengers to move between carriages during 2-car operations, they have to wait for the train to stop and the doors to open, then alight from one car and board the other.
• Passengers have the ability to sit on either ends of the car, accommodating more seating space.

Livery[]

When the line first opened, the livery of the trains consisted of two turquoise stripes painted onto the blue train cars. In 2005, the trains were repainted with a single red stripe painted along the same blue shaded train car.

Experimental programmes[]

• Some train cars were installed with solar windscreen on one of the car ends. This was to minimize heat and light from entering the trains, which were one of the main causes for warmer trains. The experimental windscreens were successful as they were subsequently rolled out to other train cars.
• The trains used to had 2 LCD displays on each train cars for advertising purposes, but was deactivated around 2009/2010 and subsequently removed.
• Car 116 was installed with the new bright LEDs used on C801A trains, replacing the existing yellow headlights. As of September 2018, all the train cars have been replaced with brand new LED headlights.
• Car 102 and 119 were installed with CCTVs under the carriage of the train.

Train formation[]

The configuration of a C801 in revenue service is M. It has both the motor and the third rail current collector, and is 12.8 m (42 ft 0 in). The train cars can be coupled up to 2 cars during service.

The car numbers of the trains range from 101 to 119. Individual cars are assigned a three-digit serial number by the rail operator SMRT Trains. A trainset consists of one motor car, e.g. set 101 is car 101. The first digit is always a 1, while the last two digits identify the car number.

• Bombardier Transportation built sets 101–119.
