Teton Trucking Company based in Knoxville, Tennessee says that their driver was delivering circulars to the Philadelphia Inquirer plant, located at 800 River Road in Conshohocken.
They say his GPS took him down River Road in Philadelphia where he got stuck on the train tracks.
The incident impacted SEPTA's Norristown Regional Rail Line.
By Tuesday afternoon, SEPTA said trains were running on the line again.
However, commuters may still experience some delays.
