The overhead power lines at Stafford railway station had to be switched off while emergency services rescued a man who suffered "extensive burns" from overhead cables.
An investigation has now been launched by the Rail Accident Investigation Branch (RAIB) as it appears the man somehow came into contact with electricity from the lines.
The power was back on by 10am but trains were delayed while the rescue operation took place.
National Rail spokesman Ben Herbert said the man was not on the station at the time, and said it was not yet clear whether he had been a National Rail worker or a contractor.
The man, in his 20s, was taken to the major trauma centre at the Queen Elizabeth Hospital.

Ron Street, a friend of Gillian Astbury's, has said: "Today’s acknowledgement of guilt by the Trust does little by way of justice against those individuals who permitted such unsafe practices for so long".
"Senior members of the [Mid Staffordshire NHS] Trust Board, who were responsible for implementing this system of unsafe work at the hospital whilst Gillian was in their care, have never been held to account"
The Health and Safety Executive has said "Her [Gillian Astbury's] death was entirely preventable. She did not get the insulin she needed to control her diabetes."
Our thoughts remain with the family and friends of Gillian Astbury and we apologise for the dreadful care Ms Astbury received at Stafford Hospital in April 2007.
We have been very open and candid and have cooperated fully with the Health and Safety Executive throughout its investigation.
The Trust offered no defence to the charge which the Health and Safety Executive brought against it today and accepts the court's decision to refer the case to the Crown Court.
Although of little consideration to Ms Astbury's family, we can assure them that we have done everything we can to put right those things which went so very wrong in 2007 and that the standard of care now provided at the hospital has improved considerably over the last few years, as has been recognised by many independent organisations and individuals.
The case of Gillian Astbury has been sent to the Crown Court for sentencing.

The inquest found low staffing levels and a systemic failure to provide adequate nursing facilities were both contributory factors.
Staff failed to give Mrs Astbury insulin, amounting to a "gross failure" to provide basic care, the jury ruled.
She had been admitted in April 2007 for treatment for fractures to her arm and pelvis.
