MTA's Robotrains prove to have a mind of their own as some go rogue on L line

In one incident, a train that was stopped at a Brooklyn platform took off on its own - traveling three to five feet before a crew member on board hit the emergency brakes, NYC Transit confirmed yesterday.

With two other similar incidents recently on the Brooklyn-to-Manhattan line, the agency suspended use of the computerized train control system on Aug. 16, NYC Transit said in a statement yesterday.

Train service continued the old-fashioned way - with motormen doing the driving, not computers - until software fixes were finished last weekend, the agency said.

The so-called Robotrains are part of an expensive package of upgrades involving subway signals, switches and onboard computers that only exists on the L line.
