Bedford train crash LIVE: Multiple passengers injured in horror two train smash

The train crash outside Bedford appears to have been a “relatively slow speed collision”, a rail expert has said.

Tony Miles told Sky News the damage to the trains looked “fairly minimal”.

He said: “Obviously it’s a rear end collision, they were going in the same direction, so one of them, the rear one was going faster than the one it’s caught up with, for some reason. That’s not a complicated assumption.

“So, the question has to be how has that train that’s in the rear got into contact with the train that it was following, and obviously it’s either gone past the signal that was telling it it should stop, or the signal was faulty, or the driver’s made a mistake in some way, or didn’t read the signal, or something.

“Over the years, all of those different scenarios have happened, and it’s now a question of finding out why did one train catch up with the train that was in front of it, that was obviously going more slowly. Whether it was stopped. I don’t know, but I say from the collision damage it looked like a relatively low speed collision.

“So either the train in the rear was already slowing down or they were both going fairly slowly, and something’s happened, but it’s not a high speed crash, certainly from the damage.”

He added: “Even if you’re going 40 miles an hour and you come to a halt in a few meters, you’ve got the energy of a 40-mile-an-hour body in you, and you’re going to move until you hit something, unfortunately. So, even relatively low speed collisions can be dangerous for people that are on board.”
