i went to johor by train once, it was midnight, cant sleep, noisy bumpy all the way and u constantly in fear that u could missed out the station if u were overslept. not recommended if u hav meeting or any important matter but other than that it was a good exp, wouldnt mind taking it one more time next time.

train stop at multiple stations and i dont see any staffs walk around to wake ppl up. maybe u have to inform them in advance. i also notice most of the staffs that work during the midnight shift at each stations were all sleeping, it would be nice if there is an announcement so that we know what station is next.

come to think of it, i dont think u can sleep with all the noises and bumps.
