New MRT interchange stations

The best interchange stations were at City Hall and Raffles Place. It was possible to change from one line to another on the same level. This was possible as the two lines were developed at the same time.

The worst interchange stations were at Outram Park and Dhoby Ghaut. The commuter has to walk a long distance to change from one line to another. Similarly, the walking distance between the two lines at Bishan is quite far. When a new line is built at a later time, after an existing line is operational, it is necessary to build the station at a distance from the existing station, due to safety and engineering reasons.

But there is another approach that allows the interchange stations to be build close together to reduce the walking time. In developing the new station, it is possible to build a new platform for the existing line, and to divert the existing line to use the new platform at a later date. I hope that the engineers consider this possiblity, so that the walking distance is reduced.
