There is disclosed herein an electrical rail coupler assembly ( 1 ) to maintain in use electrical contact between adjacent railway carriages. The assembly ( 1 ) includes a pair of complementary coupler sub-assemblies ( 5 ) securable together in use to maintain electrical contact therebetween. Each coupler sub-assembly ( 5 ) includes a base ( 10 ) to be fixed to a respective one of the carriages. A body ( 15 ) is attached to the base ( 10 ) and at least one electrical plug portion ( 25 ) engages an electrical receptacle portion ( 26 ) of the other sub-assembly ( 5 ) so that the sub-assemblies ( 5 ) when secured together are electrically connected. The electrical portions ( 25, 26 ) are moved, into electrical contact engagement by relative movement, in a predetermined direction by at least one of the bodies ( 5 ) being movable in the direction relative to its associated base ( 10 ) to provide for engagement and disengagement of the plug and receptacle portions ( 25, 26 ). Securing means ( 30 ) extends between the bodies ( 15 ) to releasably secure the bodies ( 15 ) together with the plug and receptacle portions ( 25, 26 ) in electrical contact.
