Question about Singapore to Malaysia travel & Visa req?

If you are still in India, get the Malaysian visas - if not, then from Singapore, take a plane to KL- making sure it lands at KLIA..... [condition: entry point must be KLIA]- there is a reason for this rule-please respect it. The train station is nowhere near KLIA. I suppose you are allowed to take a train from KL back to Singapore, but check with the Imm officer at KLIA on arrival from Singapore.
