Here's a diesel for you
 

EMD G12, export version. 567 cu.i. (per cyl), 12 cyl. 2-stroke, roots blower.
Built 1953 in Canada, shipped to Europe for demonstration runs, sold to Swedish state railways, later restored by Norwegians.

Beautiful scenery from northern Sweden, unbeatable sound experience (turn up the volume!) and a W115 Mercedes visible at 4:29

At idle, that train is smoooth. It's just a bit louder than my 617 when under load.:D

I also like the "superhero" style GM logo.:cool:
