Yet another completely bone-headed move by Bangkok transportation planners. The profound lack of coordination and foresight is unbelieveable.
I certainly hope the closure doesn't come to fruition. The marginal benefits of slightly faster/easier river crossings that result from the end of single-tracking at Saphan Taksin are surely outweighed by the inconvenience to the 50,000+ daily commuters who will have to make the journey to Surasak on foot.
It seems that two tracks and two platforms at Saphan Taksin is an impossibility, due to the height of the bridge approaches. But what about the other side? Could a new station be built on the Thon Buri side, such that commuters and visitors on all the hotel shuttle boats could go there? I doubt it, but I haven't looked closely enough to really assess it.
