Railfan Trip: 8-21-17: Yard Power Closeup

Amongst the several sets of yard power sitting there was this pair of SD-40-2's, that could very well be on home rails. Their lack of dynamic brakes means there's a good chance they're former Missouri Pacific units.

This end of the yard can be safely accessed due to it being next to Knucklehead's Saloon (in fact you can eat and drink  while watching trains from their balcony).
