Last evening (Friday, 9th April 2010), the Harbour line trains were running late by over 40 minutes. And the reason for the delay seems pretty unbelievable.
The trains were late because a Andheri to Panvel train reversed at Wadala to head towards Andheri instead of Panvel!In what is termed as a sequencing error, the motorman reversed the train after getting a signal from the cabin. It was only at King's Circle that the mistake was realised and then the train was cancelled at Mahim. On a funny note, whoever purchased a return ticket must have been surprised that his return journey would be really fast ;) Anyways, the consequence was obvious.
