Wisma Kastam which currently houses the state Customs Department was formerly the Malayan Railway Building that sat alongside trading offices and warehouses built in the 20th century.
Back when it was called the Malayan Railway Building , the station is believed to be the only one in the world without a rail. Instead of platforms or trains, it had administrative offices, a ticketing booth and a first-class Railways Restaurant with Bar and Grill.
Passengers bought their tickets at the Penang Railway Station, walked to the Railway Jetty at the end of the China Street Ghaut and boarded the Railway Ferry Streamers to Prai to catch the train. Fares to and from Penang were inclusive of the ferry ride.
