By train

Singapore is the southern terminus of Malaysia's Keretapi Tanah Melayu (Malayan Railway or KTMB) [19] network. There are two day trains (the Ekspres Sinaran Pagi and Ekspres Rakyat) and a sleeper service (Ekspres Senandung Malam) daily from Kuala Lumpur, and also a day train (the Lambaian Timur departing Singapore at 4:45AM) and sleeper (Ekspres Timuran departing at 6PM) daily along the "Jungle Railway" between Singapore and Gua Musang (Lambian Timur) or Tumpat (Ekspres Timuran), near Kota Bharu in the East Coast of Malaysia. Trains are clean and fairly efficient, but slower than buses. See Malaysia#By train for details about fares and travel classes.

KTMB tickets in Singapore will be charged in dollars, while those bought in Malaysia will be charged in ringgit at a 1:1 rate. A ticket which costs RM10 (2.32 Euros) in Malaysia will thus cost $10 (5.75 Euros) if bought in Singapore. There are three ways to avoid paying double:

1. Book your tickets as return tickets from Malaysia. For example, Kuala Lumpur-Singapore-Kuala Lumpurwill be charged at the ringgit rate.
2. Cross the border by road and then board the train at Johor Bahru. Note that making a reservation is highly advisable; the easiest way is to book online.
3. Buy the cheapest ticket you can from Singapore to JB, then your 'real' ticket from JB onward. Change to your 'real' seat after crossing the border.
4. Book your tickets online at KTMB's web-site, but it has to be done 48 hours in advance.

The small colonial-era railway station in Tanjong Pagar at the southern edge of the CBD has closed down on 30 June 2011, and all KTMB trains now depart from the Woodlands Train Checkpoint near the Malaysian border. This means that immigration formalities go back to normal international practice - Singapore immigration followed by Malaysia immigration at Woodlands, then Malaysia stamps you in at Woodlands. In the reverse direction, Malaysian immigration checks are carried out on board the trains at Johor Bahru, and the train then heads for Woodlands where Singapore customs is located.
