Alstom Metropolis C751A
The Alstom Metropolis C751A trains are the first generation of communication-based train control (CBTC) rolling stock that has been in use in Singapore’s Mass Rapid Transit (MRT) lines since 2003. 25 trainsets were purchased for the North East Line.
==Overview==
A development in Singapore's MRT history, the six-car trains on the North East Line are powered by overhead catenary, in contrast to the train cars on all the other operating lines prior to this, which are powered by a third rail. This was partially because authorities consider overhead wires to be unsightly and it does not allow for trains to be powered using this method on elevated lines. Since this line is the first to be fully underground in Singapore, the authorities had a choice between powering the trains on this line by overhead catenary or third rail, together with the sharing of a depot with SMRT Trains Bishan Depot.〔(【引用サイトリンク】 title=Singapore Northeast Line: will soon be the largest, fully automatic metro system in the world )〕 An overhead catenary power supply was decided upon and so, a new depot was built at the Sengkang Depot. This is also the first time in Singapore's MRT history that the seats in every compartment of the train are made up of the same colours.
Alstom was contracted in 1997 and 1998 (as Contract C751A) by the Land Transport Authority (LTA) in Singapore to supply for its North East Line in 2003.
