'Runaway' by Steve Berkovitz

The testing of a new high-speed train is thrown into panic when the computer locks out the controls and sends the train hurtling out of control. The train driver’s distress call is detected by John in Thunderbird 5, and he immediately informs Tracy Island. Leaving Alan to cope with Grandma’s cooking, Scott elicits the help of an unwilling Brains and sets off in Thunderbird 1. Arriving above the train, Scott lowers Brains down to the driver’s carriage using a line shot out from a hovering Thunderbird 1; after a few hair-raising failed attempts, Brains and Scott manage to get aboard the train, only to find that the computer is able to block all attempts to rewire its systems. Realising that the runaway train is about to hit a passenger train on the same line ahead, John manages to switch tracks just before the crash; but now the rogue train is heading straight for the terminus – and unless Brains can find a way to get past the computer, thousands of rush hour commuters will die!
