A sleeper for supporting two parallel rails. The sleeper comprises a hollow elongate body having a slot in an upper surface of the body for receiving cables. The slot extends at an angle to the length of the sleeper such that a first end of the sleeper has a relatively wide portion on a first side of the slot and a relatively narrow portion on an opposite second side of the slot, and a second end of the sleeper has a relatively wide portion on the second side of the slot and a relatively narrow portion on the first side of the slot. Each relatively wide portion is provided with a rail fastening member adapted to fasten a respective different rail to the sleeper. The sleeper is formed from metallic sheet material, and the upper surface is reinforced beneath each rail fastening member by an angled bracket running the length of the rail fastening member.
