SMRT Trains

SMRT Trains Limited is a rail operator in Singapore and a wholly owned subsidiary of SMRT Corporation. After the privatisation of the MRT operations in 1995, it was originally named Singapore MRT Limited. On 31 December 2001, it was renamed SMRT Trains Limited, so as to avoid confusion with the then upcoming North East MRT line which would be under SBS Transit. SMRT Trains currently manages most of the MRT services in Singapore except the North East Line and Downtown Line.

History
SMRT Trains Limited was incorporated as the rail subsidiary arm of the parent company SMRT Corporation, to oversee rail operations brought over from the previously state-owned Mass Rapid Transit Corporation (MRTC).

Mass Rapid Transit Corporation (MRTC)
The Singapore MRT Limited was incorporated on 6 August 1987, and signed the licence and operating agreement (LOA) with MRTC, a government-run corporation till 1997. On 7 November 1987, MRTC started services on Singapore's first MRT section, consisting of five stations from Yio Chu Kang to Toa Payoh. When the MRTC merged to form LTA on 1 Sep 1995, operations of the MRTC were hived off into SMRT Corporation. On 1998, the light rail operation was formed and was called Singapore LRT Limited. On 31 December 2001, both Singapore MRT Limited and Singapore LRT Limited were merged into the present name, SMRT Trains.

Transition to New Rail Financing Framework (NRFF)
On 15 July 2016, SMRT Trains and its subsidiary SMRT Light Rail concluded discussions on the transition of the North–South and East–West lines (NSEWL), the Circle Line (CCL) and the Bukit Panjang LRT (BPLRT) to the New Rail Financing Framework (NRFF). The framework, announced by the Government in 2008 under the Land Transport Master-plan, was introduced as an enhancement to the 1996 Rail Financing Framework, and was first implemented for the Downtown Line (DTL) in 2011. SMRT transited to a 15-year contract under the new framework from 1 October 2016, with the transfer of ownership of all its rail assets at a net value of $1.06 billion to the government.

SMRT Trains currently operates a fleet consisting of seven rolling stocks built on its two heavy rail lines (the North–South Line and the East–West Line) – namely C151, C651, C751B, C151A, C151B, C151C and R151, identified by the relevant build contracts.

Notable incidents

 * Clementi rail accident: On 5 August 1993, before the start of service, a maintenance vehicle spilt oil on the tracks between Clementi and Jurong East. The first ten eastbound trains reported braking problems. Then, at 7.50 am, the eleventh east-bound train from Jurong stopped at the Clementi Station for two minutes longer than scheduled due to it using its emergency brakes to stop at the station, and was then hit by the twelfth east bound train when it failed to stop in time. 156 passengers were injured by the collision.
 * Pasir Ris rail accident: On 22 March 2016, 2 SMRT staff were killed when a train hit them near Pasir Ris station along the EWL. Following an audit and investigation, the Ministry of Manpower reported that SMRT had failed to follow safety procedures to ensure worker safety for the past 14 years. Former assistant engineer Lim Say Heng pleaded guilty to one charge of causing the deaths of the trainees  by failing to observe critical safety protocol and was sentenced to four weeks jail.
