Bombardier owns 50% of CBRC and its share of the contract is worth around $US 46m.

Delivery of the additional vehicles will begin in 2016, following on immediately from the initial order of 73 three-car trains, five of which have already been delivered. The first 11 sets are due to enter service this October on the initial 4.3km section of the Downtown Line between Chinatown and Bugis, which is currently being commissioned.

The 16.6km Stage 2 from Bugis to Bukit Panjang will be completed in 2015 while the final 21km eastern section from Chinatown to Expo will open in 2017. The line will be operated by SBS Transit and when it is completed will be one of the longest driverless metro lines in the world.
