Technical Terms
12 car Push-out A 12-car rescue operation will be launched in the event of a train breakdown. This involves connecting a rescue train to the defective train and towing it to the nearest station. The defective train will then be sent back to depot.
Train Fault Faulty/ defective train due to:
  • Train circuit failure
  • Power trip
  • Platform door fault
Signal Fault Fault on the signal code generator which controls/ defines train speed(s)
  • Defective signal connector (transmits information from the train to the station)
  • Fault in signalling equipment along the track

A signalling fault will cause a loss of traction power and the train will stop.
Track Fault Track circuit failure due to:
  • Cable fault that leads to a loss in traction power
  • Damaged Insulating Rail Joints (IRJs)
    • IRJS provide insulation along the running rail between two track circuits
Power Fault Traction power loss due to:
  • Faulty cable due to deterioration over time
  • Faulty cable coupled with tunnel leakage that will cause a power trip in the circuit breaker
    • Tunnel leakage is a common occurrence in SMRT’s train lines
    • But not in its main NS/ EW lines as those are equipped with a drainage system
  • Electrical earth fault that disrupted power supply, which in turn interrupted the signalling system
3rd Rail The third rail is an insulated steel rail that runs parallel to the entire length of track. It feeds electricity to the train through collector shoes, which are metal blocks under the train
Re-signalling Replacement of the signalling system to improve train frequencies and to help reduce waiting time for commuters.
  • Upgrade will allow trains to run at intervals of 100 seconds at peak periods, compared to the existing intervals of 120 seconds
  • This would translate to shorter waiting times for passengers and,
  • A potential 20% improvement to existing capacity
Rail cracks Cracks in the third rail that are mainly caused by metal fatigue contributed by a combination of temperature and age.

Usually found in the joints of the rails or when the track curves.
Restricted Manual (RM) Mode In RM Mode, the train is operated manually and its speed is limited to a maximum speed of 18km/h. The train will be placed in “Forward”, “Stand-By” or “Reverse” mode, according to the demand of operation. This mode is normally used when the train is inside depot or when ATC (Automatic Train Control) system fails.
Automated Mode (AM) Normal mode of fully driverless operation
AM allows the train operator to just handle operating the doors and to look out for obstacles. ATO system (system that automatically operates the train) is activated in AM mode, based on ATP (Automatic Train Protection) speeds and station stopping profiles. AM mode is usually used during normal service hours.
CCD (Current Collector Device) Part of the train that makes contact with the power-supplying third rail. Each train has 24 CCDs
WILD (currently being installed at selected stretches of the NSEWL) Fibre optic sensors automatically detect and identify the locations of any wheel defect on all our operational trains during revenue hours
When a wheel defect is detected, an alert is sent to the Operations Control Centre and Rolling Stock Maintenance Controller so that immediate actions can be taken to rectify the fault
Preventive Maintenance Early detection of faults to allow engineers to identify and rectify them quickly, so as to avoid causing inconvenience to passengers This is possible through SMRT’s adoption of new technologies such as:
  • Automated Current Collector Devices (CCD) Detection System
  • Wheel Impact Load Detection (WILD) System
  • Linear Variable Differential Transformer (LVDT) System
Predictive Maintenance Identify potential technical issues before they cause service disruptions
  • Implemented monitoring and tracking systems and processes
Train Withdrawal A faulty train is withdrawn from service
ISO 55001 Certification ISO 55001 Certification specifies requirements for the management of infrastructural assets.
It is an internationally – recognised standard and adopted as a benchmark for SMRT’s management of rail infrastructure and assets
Maintenance Regime (Cleanliness) Total sum of maintenance applied to SMRT’s rail assets
  • Exterior of trains are thoroughly cleaned every 3 weeks
  • Interior of trains are cleaned daily

Technical Terms
Bus Contracting Model (BCM) Adopted on 1 September 2016, the Bus Contracting Model (BCM) brings all public buses and related infrastructure such as integrated transport hubs, under the ownership of the government. The BCM sees LTA planning bus services centrally, while public transport operators bid for the right to run services along the bus routes. Bus operators are paid fees to run bus routes at service standards set by LTA. The tendering process drives competition in the bus industry and encourages operators to become more responsive to changes in ridership and commuter needs. This in turn will raise the reliability of bus services and improve waiting times for commuters. The model also spurs operators to step up recruitment, staff training, upgrading and professionalising the bus workforce.
BSRF (Bus Service Reliability Framework)

Previously known as the Quality Incentive Framework, it assesses the regularity of a bus service using the concept of Excess Wait Time (EWT) and On-Time Adherence (OTA). Under the BSRF, bus operators are given incentives to improve their EWTs and OTAs.

Career Progression Framework for SMRT Bus Captains (BCs) BCs will receive tailored training under the SMRT BC Scheme to be equipped with skills to provide better service to commuters and increase their productivity level. These include basic driving skills as well as service and supervisory skills. The scheme also includes training plan to enable career progression into supervisory positions.
