Install sensors to stop train when obstacle is detected

Perhaps SMRT could study if it is possible to fit trains with proximity laser sensors ("SMRT orders safety review after train runs into two"; yesterday). These sensors can slow a vehicle down and eventually make it stop, should it detect an obstruction ahead. They are fitted in automated guided vehicles used in warehouses and hospitals.

Another suggestion is to install cameras in the front, back and sides of trains. Footage from these cameras can aid investigations of any incident.
