Crash averted!

Train

Mr Kumar, who works as a railway traffic controller, had the most scary experience ten years ago. This is what happened: The "Gujarat Queen" left Ahmedabad at 6.30 am and headed for Vadodara situated 100 kilometres away while travelling at a speed of 50 km per hour. The "Vadodara Express", meanwhile, started from Vadodara at 7.00 am and travelled towards Ahmedabad at 40 km per hour.

At 7.30 am, Mr Kumar, who was then at Vadodara, came to know that both the trains were running on the same track! Mr Kumar acted at once, and caused both the trains to halt. Thanks to Mr Kumar, a major accident was averted. But just supposing that the blunder had not come to anyone's notice, can you determine as to when the two trains might have collided?
