Yes, it's odd. It seems there are lots of worksongs relating to agriculture, roadbuilding, railroad laying, sailing etc. but very few to actual ships and even fewer to trains.

I have a show called Transatlantic Conversations on Celtic Music Radio here in Glasgow and I do a lot of comparison stuff, eg how Child ballads turned out across the water, modern folky stuff that's given different treatment (e.g. First Girl I Loved, Jackson Browne version), similar themes for songs.

I've got a song about the decline of the locomotive industry in Springburn, Glasgow, and was looking for an American song that fills the same niche - but, given the paucity of material, I'm willing to take anything that refers to the industry whether in growth or decline.
