Welcome to the second attempt at rebooting this thread! Last week, Jeff Sohn posted a great video of his custom K-Line Union Pacific SD70Ms, which you can see here. I also found the thread from August 18th, 2018, which had 16 replies running the gamut from quarter-scale steam to subways, Daylights, and the Lehigh Valley, which you can see here.
This week, I'm posting a cab ride (best viewed at 2x speed using the settings gear on the YouTube window), and some vintage Alco DL353 action in the shadow of Macchu Picchu.
