If you have ever used BTS Saphan Taksin then you would know about the bottleneck that is caused here by having only one platform. If you catch a train here you need to keep an eye on the monitors as it will tell you which direction the train is going. In August 2013, the extension of the skytrain will open from Wongwian Yai to Bang Wa and it is expected that the daily number of commuters will increase greatly. As a consequence, the Bangkok Metropolitan Administration (BMA) is considering demolishing BTS Saphan Taksin station in order to eliminate this bottleneck. According to a report by NNT, BTS Saphan Taksin was always intended to be a temporary station. If this plan goes ahead to demolish the station, commuters who want to transfer to the boat service at Sathorn Pier will then have to get off one station earlier at BTS Surasak. The BMA will then build a one kilometer long skywalk which could be fitted with travelators to help passengers finish their journey to the former BTS Saphan Taksin station.
Please note, this may never happen, and if it does, it will probably be a couple of years before the project is finished.
