MP Jonathan Reynolds has written to railway bosses, after commuters turned up at Stalybridge station on Friday to find the gates into the ticket hall were locked.
Without access to the station, passengers could not safely get to the west-bound platform in order to board the 6.34am service to Manchester Airport.
Most commuters joined into small groups to take taxis from Stalybridge to the stations at Manchester Piccadilly or Manchester Airport.
However it is understood a small number of commuters jumped down onto the tracks and ran to the other side, in order to catch the train.
Witnesses said a non-stopping high-speed train passed through the station just a few minutes later – prompting fears that the actions of the rail passengers could have been far more serious..
Mr Reynolds is “extremely concerned” by the incident. He has written to bosses at First Transpennine Express – which operates the station – to ask for an explanation of why the station remained locked.
Furthermore he has asked for assurances from the company that procedures are now in place to ensure that this does not happen again.
"Crossing railway tracks is extremely dangerous - and it cannot be condoned under any circumstances,” said Mr Reynolds.
“It is illegal and clearly no journey warrants this level of risk taking.
"However I do understand the extreme frustration felt by passengers who tell me they found the station locked and who were therefore unable to reach their train.
"First Transpennine Express has a responsibility to make sure that passengers are able to access services - and it is not acceptable for stations to remain locked.
"I have written to the company asking for an explanation of the circumstances leading up to this incident and for assurances that this cannot happen again."
