The order is intended to compliment asignificant capacity enhancement project which began recently at Jurong East,where North-South and East-West lines converge. Trains on both lines share themiddle platform at the station, which has severely limited capacity in recentyears. Construction is now underway on a new fourth platform and realignment ofthe track on the approach to the station, together with a new 2.5km viaduct,which will accommodate an additional track.

The completion of this work in 2012 togetherwith the delivery of the new trains will allow capacity to be boosted by around15%, with minimum headways of around two minutes during peak periods.
