A new variant of GoTRAX<\/a> vision based navigation system is GUARD – GoTRAX Used As Rollback Detection which is a safety device to fit to trains to detect unintended movement or “roll-back” as mandated for trains using London Underground infrastructure.<\/h3>\n<\/div>
<\/div><\/div><\/div>

GUARD sits behind the windscreen of the driver cab and communicates with the vehicle’s systems sending a current state of movement signal, reversing\/not reversing. The system uses pre-defined parameters to determine whether any movement is acceptable and intentional and if not, will send a signal to the vehicle’s systems which may be used to apply the brakes.<\/h3>\n<\/div>
<\/div><\/div><\/div>

Fitting GUARD, or GoTRAX<\/a>, requires no modification to the train’s envelope and no additional power sources. GUARD is interfaced with the train’s existing systems and can be fitted very quickly with minimal disruption.<\/h3>\n<\/div>
