LONDON — It was the stuff of urban nightmare and Hollywood action film: a runaway maintenance train on London’s Underground system heading downhill for 13 minutes — four miles — toward the heart of the city as the authorities worked frantically to clear its path of trainloads of unwitting commuters.
The peril came to an end that would be disappointing in a movie but was in fact reassuring in its dullness, as the train simply ground to a halt on an uphill stretch of track.
Commuter traffic was, naturally, disrupted for hours. What exactly went wrong remains a mystery for now.
