A control handle assembly (10,110) for a rail vehicle such as a train or metro includes a driver's handle (14,114) which incorporates a Deadman's feature by which the handle (14,114) can fall to a lower position by means of gravity in the absence of a holding force applied by the operator. A rest plate (130) is provided on the handle (114) to allow the handle (114) to be kept in its operative position whilst minimising driver fatigue. An alertness check requires movement of the handle (114) to its non-operative position at periodic intervals. The handle (114) and other driver controls (116) are coupled to a control unit (12) by a magnetic sensor system (146,148) which reduces operator strain by avoiding mechanical links. <IMAGE> |
