Here is a neat Santa Fe diesel PA-1 by Athearn. Tested and works.
Someone went to some effort to install the Sagami motor and the MARS light. However, the unit needs some cosemtic TLC (unless you are swqapping shells, of course). See condition notes below.
CONDITION: C-5. Tested and runs and lights. Mars light works. Has cosmetic needs. Looks to have been clearcoated in a weathering attempt. One side number decal mostly worn off. Needs rear coupler. Broken step. A few nicks. No box.
This one is running nice, but it is always a good idea to lubricate these used locomotives before extensive run time since we do not know how long they have been sitting.
