What I dont get is the JB Sentral train station officer informing me they are not able to issue anymore tickets when the seats are sold out. I dont mind standing as long as I can buy a ticket since it is only a 5-minute journey. Yet I can see a few other passengers standing and the seats are all occupied in my carriage & the next carriages.
The limitation on the no. of tickets has less to do with the physical seats available, it has more to do with the capacity of Woodlands Train Checkpoint. If unlimited tickets were sold, it could bring things to a standstill and derail the train schedule (no pun intended). Being a cross-border service, the no. of tickets, the frequency of the train etc. are coordinated, negotiated and agreed upon between the Malaysian and Singapore authorities, it's not up to KTM to implement more trains, seat etc.
Btw, bad news for shuttle train lovers, online booking and booking more than 1 day in advance is no longer possible from 1 December:
