Nice detail photos. The first one appears to be an EMD F59PHI. The 2052 is a GE P32-8WH or Dash 8-32BWH depending on what reference information your read. These are ‘Dash 8’ technology engines, and Amtrak has a small fleet of them. These engines were built in 1991. Walthers has marketed an HO model of the Dash 8-40BW painted in the Amtrak ‘Pepsi Can’ paint scheme. You can still find them on eBay…
So what is the difference between the GE 32-8? and the GE CW44-9? Asthetically they look the same that I can see, with the exception of the window in the nose access door.
