Fake news saying that long distance trains are now leaving from the new Krung Thep Aphiwat Terminal Station (Bang Sue Grand) is continuing to spread.

 

 

Yes, good find: THIS is indeed the new name for this terminal, not so new anymore, but for use of trains yes. Reason: only trains with toilets that do not drop the droppings on the tracks are allowed to enter this high-level all-concrete thing. That rolling open-air museum that the SRT is in fact, had too few of these.

BUT rescue is near: it is now planned for dec. to switch the best trains (labelled as SP=Special Express, with extra high surcharge and no 3d class) to it-new loco are also coming in. These trains seen on the ´socials´ are in fact training runs for the drivers (how to get up the slopes without failing or running backward........ Again Japan was willing to sell for a few yen some old stock of Nihon/Yipun. The track gauge is a few cm different-but thats easy to resolve.

The less graded trains locals/rapid etc will as for now continue to start/finish at old HuaLamPong, but will shortly be restricted to Bang Sue-flat level (next to the new terminal, the old junction). This includes the 1/day (mo-fr only) early morning train to Patters.

(this from a very well informed Thai person/former senior SRT official who keeps track of all developments, in Laos too, on trains/rails in another world-wide forum).
