These stamps are to be issued on 28 May 2009. They depict the Mass Rapid Transit or MRT (in short) that will see an increase in the number of train stations with the building of the 33.3 km Circle Line which will be joined to the existing rail stations. The MRT is basically a train transportation system for the public like the Tube in London. For the Circle Line, another 29 stations will be added and they will all be fully underground.
