(54) RAIL COUPLING


(57) A releasable rail coupling 1000 for releasably coupling a first rail 10A providing a first portion P1 of a running surface RS for a wheel 120 and a second rail 10B providing a second portion P2 of the running surface RS is described. The rail coupling 1000 comprises a first part 1100 having a first end 1110 comprising a first male coupling member 1111 and a second end 1120 arranged for joining to the first rail 10A. The rail coupling 1000 comprises a second part 1200 having a first end 1210 comprising a corresponding first female coupling member 1212, arranged to receive the first male coupling member 1111 therein, and a second end 1220 arranged for joining to the second rail 10B. The rail coupling 1000 is arrangeable in a first configuration wherein the first male coupling member 1111 and the first female coupling member 1212 are uncoupled. The rail coupling 1000 is arrangeable a second configuration wherein the first male coupling member 1111 and the first female coupling member 1212 are coupled by receiving the first male coupling member 1111 in the first female coupling member 1212. The rail coupling 1000 provides a third portion P3 of the running surface RS in the second configuration. In this way, assembly and/or disassembly of the first rail 10A (i.e. a first length of rail) and the second rail 10B (i.e. a second length of rail) may be facilitated and/or errors in assembly reduced.
