LM 238 crossing the Grand Canal (Ted McAvoy)
It shows a Bord na Mona ballast train crossing the Grand Canal just here. It’s on the BnM’s Derrygreenagh System and, if you follow the line northwards on the map, you’ll get to Derrygreenagh on the R400. I am told that the train was going to Ballybeg Bridge Quarry but I haven’t managed to locate that.
