So,... Monday evening N was looking for train songs, to put in Thursday's GoingSideways.blog post, Colorado and the Midwest. Just about the first one that came to mind was "The Last Train" (lyrics here) by Janis Ian. So of course I had to go listen to it again, because I love it. It made me cry.
I don't know why -- it always surprises me when I come across another trigger. But I'm not complaining. I don't cry enough.
For a total change of mood, gorgeousgary's comment on my signal boost post pointed me at "Roll On Jamaica/Agnes on the Cowcatcher" from the Canadian band Tanglefoot (lyrics on mudcat.org). It's based on an actual historical incident.
Then acelightning73 added half a dozen more.
