API620/BX620 locomotives

[edwin87]

I've been doing some searching on the internet regarding the RSD5 rebuilds that the FCP performed.  I have found many good pictures and have some footage on the Pentrex videos "Those Incredible Alcos - Vol 3" and "Mexico's Pacifico Railroad".

My guess is that I can start with an Atlas RSD4/5 HO locomotive.  From what I can tell, it looks like I will reuse the cab from it and the rest of the long hood would need to be scratchbuilt while the nose on the API could be derived from a GE U-boat or a Century C424/C425 if building the BX version.

I tried to find some drawing or plans on either the API620 or BX620.  Does anyone have a link to where I might find some.

I wonder if any of these locomotives survive today?

Hi Edwin.I'e been throwing the idea around myself lately with those 2 engines.I also have the alco videos;try a Google search for pictures as I haven't seen any dimension data.You seem to have the right parts lined up for the frame and cabs.
My plan was to cut and cement 2 Atlas rs36 hoods together;that way you won't have to scratchbuild them and all you will need is to make the flat rear hod with the large fan,probably like the PA used.Since there are 2 variations,one has the dynamic brakes like the century and I believe the other has the one from the roadswitcher version.
Either way,you could splice in the parts from Atlas units.
Keep me posted,
