In 1904, the Sultan of Johore signed off a 194 km line between Gemas and Johor Bahru which was completed in 1909. There was now an almost continuous rail link between Singapore and Penang excluding the crossing of the Straits of Johor, which was served using two boats named Singapore and Johore. In 1913, the Singapore-Kranji Railway was sold off to FMSR at a price of $4.136 million in anticipation of eventual connections between the two railways. This connection was finally fulfilled in 1923 with the opening of the Causeway.
