Not a joke as such, more a funny story.
Back in the day at Limerick Junction there used be staff dorms, this one was an awful rat-infested kip with a reputation for being haunted.
Apparantly, one night a staff member supposed to be booked in there for the night, ran up to that station and swore he wouldn't stay the night at any cost.
Said he'd looked in the window and saw the Devil, Old Nick himself....poking the fires of Hell with his pr*ck.
Apparantly, there was a driver already in residence, who happened to have a goatee beard and a penchant for sleeping in the nip, had gotten out of bed to poke the fire.
