Engineering Trains in SMRT

Our Trains group employs an extensive range of specialised vehicles to maintain our rail network. Grouped under the Engineering Trains Branch (ETB), these vehicles roll out from our depots after passenger trains stand down. Below are the key workhorses of ETB which are used by our engineers when the rest of Singapore is asleep.

SMRT Track Tamping Vehicle

SMRT Track Tamping Vehicle

Used to tamp ballasts while simultaneously measuring and correcting track alignments so that they are longitudinally aligned and level. This is achieved by packing the ballast(crushed stones that forms the trackbed) underneath each sleeper so that each sleeper can support the track effectively. The packing of ballast is called tamping. Our TTVs ensure SMRT passengers have a smooth and safe ride.

Train number: TTV01, TTV02
Crew: 5 (minimum)
Weight: TTVO1: 37 tons
TTVO2: 63 tons
Speed: Limited to 18km/h self-propelled

 

Multi-function Vehicle (MFV)

Multi-function Vehicle (MFV)

A moving inspection lab, the MFV uses a rail flaw detection system to detect internal cracks within the rail in real time. The system uses roller search units with ultrasonic transducers positioned in an array of angles for thorough test coverage. Engineers aboard the MFV analyse the ultrasonic data to ensure the rails are not cracked. This vehicle also equipped with track geometry measurement system which records and check the geometry of the running rail and third rail.

Crew: 4 (minimum)
Weight: 32 tons
Speed: 18km/h self-propelled
40km/h (max speed)

 

Rail Grinding Vehicle (RGV)

Rail Grinding Vehicle (RGV)

Used to re-profile the rail heads and eliminate rail corrugation in order to reduce track stresses and to extend the service life of the rail, and ensure ride comfort. Rail grinding is applied to eliminate various types of rail defects, to achieve a rail profile that optimises wheel/rail contact and combats noise and vibration. This will also reduce service failures due to rail surfaces that are uneven.

 

Train number: RGV3, RGV5
Crew: 4 (minimum)
Weight: 118 tons
Speed: 18km/h (self-propelled), 50km/h (hauled by locomotive)

 

 

Viaduct Inspection Wagon

Viaduct Inspection Wagon

To inspect elastomer bearing mounted between the concrete grinders and columns.

CKG Diesel Locomotives

CKG Diesel Locomotives

Our oldest diesel locomotive, introduced 29 years ago. These old locos no longer ply the North South East West Line and are used to shunt (which means to haul) passenger trains within Bishan Depot when trains go there for maintenance. Mainly utilised by Rolling Stock Workshop.

Train number: D02, D10
Crew: 2
Weight: 26 tons
Speed: 18km/h

Deli Diesel Locomotive

Deli Diesel Locomotive

Our most numerous and powerful locomotive, able to haul 240 tons. Single rail vehicle powered by its own diesel engine. Can combine with another locomotive to provide propulsion for maintenance wagons and other machinery.

Train number: D201 to 215, D216 to D219
Crew: 2
Weight: 56 tons
Speed: 50km/h

Second Generation Deli Diesel Locomotives

Schöma Electrical Locomotive

Schöma Electrical Locomotive

Single rail vehicle able to move by itself or combine with another to provide propulsion for maintenance wagons and other machinery. Able to move with either onboard batteries or third rail power source. It may look small but can haul over 100 tons.

Train number: EL01, EL02, EL03, EL04
Crew: 2
Weight: 34 tons
Speed: 50km/h

Tunnel Cleaning Wagon

Tunnel Cleaning Wagon
