Siemens C651
The C651 trains are the second generation of train cars used on the SMRT network. the cost of the C651 was $259 million. They were bought mainly to allow the network to carry more passengers due to the opening of the Woodlands extension. The first train was delivered to SMRT on 20 September 1994. Unlike the first generation Kawasaki Heavy Industries C151 trains, the C651s are specially painted to reduce scratches due to dirt trapping on the outside of the C151 trains that were difficult to remove.
