Image source, Alex Pope/BBCTeresa Itabor, from Wellingborough in Northamptonshire, was on 16:57 at Wellingborough heading to the capital to celebrate her birthday.
She says she had her eyes closed and headphones in when the collision happened.
"We left Bedford station and there was a massive bang... I didn't know what was going on; my head hit the seat in front of me," she explains.
"I opened my eyes and that's when I saw people on the floor with blood everywhere."
She adds that the carriage doors had jammed and would not open.
"We really didn't know what was happening for a long time."
