Formation

The formation ranges from D001/D003 (Trainset 1) to D127/D129 (Trainset 43). Like the previous SP1900s and Metro Cammell EMUs, one car is still reserved for the first class in each train set. The 9-car formation is shorter than the previous 12-car East Rail Line trains, due to space constraints imposed by new underground platforms on the Sha Tin to Central Link. There are concerns that the new formation may worsen the existing overcrowding problem. However, the Transport and Housing Bureau and MTRC suggest that the new signaling system and higher train speeds will increase the train frequency from three minutes down to two minutes. It is also estimated that with the completion of the

This is especially noticeable in the first class compartment, where the doors are painted yellow to distinguish from standard class. The location of the doors in the first class compartment allow both to be used for normal boarding, which is not possible using the offset arrangement of previous sets. *Seats near
