What a great thread!

Train Whistle Blues - Jimmie Rodgers (circa 1930)

On the Atchison, Topeka & the Santa Fe - Johnny Mercer (1945) - this was a hit in '45!

People Get Ready - "don't need no ticket, you just thank the Lord.."

Working on the Railroad - used to play this in an instrumental duo; works really well as a funky, alternating bass fingerstyle sort of song

The Train That Carried My Girl From Town - not sure who wrote; probably late 1920s; Mike Dowling does on his Beats Working album

- Merritt
