Oh yeah, there's also Elizabeth Cotten's "Freight Train"

When I die, Lord, bury me deep
Way down on old Chestnut Street
So I can hear old Number Nine
As she comes rolling by

Merle Haggard's "Dark As a Dungeon"

I hope when I'm gone and the ages shall roll
My body will blacken and turn into coal
Then I'll look from the door of my heavenly home
And pity the miner a-diggin' my bones

Now I'm probably going to have more examples popping into my head all evening.
