ACCRINGTON Railway Station was closed for more than 12 hours after a horrified train driver spotted a body on the platform.
The station was cordoned off after the man was found face down in a shelter.
Senior detectives from British Transport Police were called in and the death was at first treated as suspicious.
But after a post-mortem examination late on Wednesday police said they no longer suspected foul play.
The man is believed to be a 35-year-old from the Accrington area but a formal identification was taking place yesterday (Thurs) morning.
The driver of a Preston-to-Colne train spotted the body at about 5.50am on Wednesday and when the conductor was unable to rouse the man they called the police.
The station was closed to rush-hour commuters as forensic teams were called in to search the area, although trains continued to pass non-stop through Accrington.
Bewildered passengers who turned up at the station were ferried away by rail replacement shuttle buses, which operated between Accrington, Blackburn and Burnley.
Normal services did not resume until just after 7pm.
One commuter said: "I turned up to catch my usual morning train to Blackburn and police were swarming all over the place.
"The station was cordoned off and I had to catch a bus, making me late for work.
"Everyone was talking about it and wondering what was going on."
A travelling funfair was only yards from the investigation scene but fair workers said they had not seen or heard anything unusual.
British Transport Police are looking into the circumstances leading up to the discovery of the body.
Anyone with information should contact them on 0800 405040 or Crimestoppers, free and in confidence, on 0800 555111.
