Don't ignore Shel Silverstein's famous one-verse train song:

Let me sing you a song 'bout the old 49 / Fastest engine on the Santa Fe line / On the 12th of December, she made a desparate dash / And she got there on time and she did not crash.

Also the old one that Joan Baez did, that I should have listed under Songs I Can't Sing Without Bursting Into Tears, about Engine 143 and Georgie, which has that fantastic imagery about the crash's effects on the engineer, even better than the Cisco Houston imagery about how "they found him in the wreck with his hand on the throttle: he was scalded to death by the steam."
