Point drive system

A drive system for railway points comprises a drive means (26-29, see figure 3) for producing linear motion along a first axis, a drive member 30 operatively connected to the drive means, the drive member being linearly movable along said first axis, a pivoted crank 32 having a profiled end and an output region, and an output member 11 connected to the output region of said crank, said output member being substantially linearly movable along a second axis orthogonal to said first axis for connection to a pair of movable rails 2, 3, such that in use the drive member engages said profiled end causing rotation of the crank thereby causing the output member and said pair of movable rails to move along said second axis. A series of additional cranks 39, 40 are connected to the drive member 30 to drive the rails along their length in a synchronised manner.
