Casey Jones  was a ghostly railroad man and apparently the ghost of the legendary engineer Casey Jones.
At the start of the 20th century, Casey Jones was an engineer in the most famous train wreck in railroad history.  In the 1980s, Casey Jones' ghost manifested at Grand Central Station just as the midnight express from New Jersey arrived on track 13. After causing some minor damage, he hijacked a train. The Ghostbusters were called for help but based on the description and time, they believed it was a prank at first.
While investigating the station, Peter Venkman was kidnapped and taken aboard an antique train. The train took off and the rest of the team pursued in Ecto-1. Some time after entering the state of Pennsylvania, the team boarded the train and trapped Jones. Upon sighting an Amtrak passenger train on a collision course with them, Peter realized that Jones wanted to help prevent a train-related tragedy before taking up eternal rest.  He released the ghost, who switched the tracks and saved the day. Peter's gamble paid off, and Jones dispersed in peace.
He loves drinks with a lot of caffeine and food that is loaded with sugar. He is very demanding of his employees. He insists that he stays ahead of schedule, no matter what.
Casey Jones appears to be Semi-Corporeal throughout the bust. When facing the Ghostbusters, Jones headbutts Winston Zeddemore in the chest but is slammed into the train tunnel.
