context_page_description: The East West line is a high-capacity Mass Rapid Transit line operated by SMRT, running from Pasir Ris station in the east to Tuas Link station in the west, with an additional branch between Changi Airport and Tanah Merah stations. It is the second Mass Rapid Transit line to be built in Singapore. The 57.2 kilometres line is the longest on the MRT network, with 35 stations, 8 of which are underground. The line is coloured green on the rail map.
  Constructed and opened as part of the North South line in the early stages of development, the East West line is formed after the opening of the eastern extension to Tanah Merah in 1989. Nevertheless, till today, both lines used identical signalling equipment and rolling stock. The EWL signalling systems have been upgraded along with the NSL and is the second line to have its signalling upgraded completely, converting it from semi-automatic to fully automated operations.
context_section_description: There are currently five models of rolling stock that operate on the East West Line. They are: The C151, the oldest rolling stock which was introduced in tandem with the opening of the line in 1987, along with the C651, C751B, C151A and the C151B which were introduced in the later years. These models of rolling stock were introduced to boost the capacity on both the North South and the East West lines in order to cope with increasing ridership.
  The East West Line and the North South Line utilized identical rolling stock up until the recent years, when the C151A was temporary suspended from operating on the North South Line between January 2012 and November 2013 following the 2011 Train Disruptions. The C151B, which was introduced in April 2017, did not begin revenue service on the full-stretch of the EWL until the line's trial of the CBTC signalling system in May 2018. The C151C, which was introduced in September 2018, is currently operating on the North South Line only.
  The CR151, will arrive in batches from 2021 and will gradually replace the first-generation C151 trains.
  These trains operate from the three depots along the line, the Ulu Pandan Depot between Jurong East and Clementi, the Changi Depot near Tanah Merah and the Tuas Depot located near Tuas Link.
