The Mass Rapid Transit system, locally known by the initialism MRT, is a rapid transit system in Singapore and the island country's principal mode of railway transportation. The system commenced operations in November 1987 after two decades of planning with an initial 6 km (3.7 mi) stretch consisting of five stations. The network has since grown to span the length and breadth of the country's main island – with the exception of the forested core and the rural northwestern region – in accordance with Singapore's aim of developing a comprehensive rail network as the backbone of the country's public transportation system, averaging a daily ridership of 3.45 million in 2023.

The Joo Koon rail accident, sometimes referred to as the Joo Koon train collision, was a crash which happened on 15 November 2017, when a C151A train travelling at 16 kilometres per hour (9.9 mph) rear-ended a stationary C151A train at Joo Koon station on the East–West MRT line, resulting in 38 injuries. The stationary train was in the process of being detrained due to a train fault. Both trains were operating under the recently installed Thales SelTrac CBTC signalling system at the time of incident, and the Minister of Transport Khaw Boon Wan expressed that he was "disturbed" by an initial finding that "critical safety software" was inadvertently removed from the stationary train, possibly due to a malfunctioning signalling circuit, which led to the crash. This incident is the second train collision in Singapore MRT's history, after the Clementi rail accident.
