Coming FROM KUL I assume its now elektrik ''steamcar'' (thats literally the Malay word for train=kereta api) until Gemas and change to what I assume are the remains of the old through trains onward. As explained: in JB the stesyen is In the giant new border check-post (stock up if any food is needed, its much cheaper as in SIN), pass thru Malay emigr, then find the busstops-there are 4: SJE Ekspres IN SIN proper, ditto from SBS, and both SBS and what used to be Causeway (may have changed) to the nearestby Metro station in SIN-SIn Immi is at their side of the causeway-if you like you can also walk over it, but it wont save on busfares (as in MY you can pay-cash only, farebox, with MYR). There may be giant jams on that causeway later in the day-do allow for plenty of time if you intend to fly out of SIN straight-away.
