Bear Attack simulator limit switch problem

I'm building a bear attack simulator using the MDC 1460 controller. The motor is at the head of the track driving a rope and pulley system which is attached to the dolly with the bear on top. I want to place a forward limit switch on the track to prevent the dolly from crashing at the end of the track. The problem is the limit switch will only be depressed momentarily as the dolly travels past the switch. The problem is once the switch is released the motor can start up again. What I want is once the forward limit switch is tripped it stops the power to the motor allowing it to coast to a stop and only allows operation in reverse direction regardless whether the switch is released or tripped again as it's moving back to the start of the track. Do I need to write script to make this happen? I have no idea who to do this so any help would be appreciated.
