I recently bought a 2-8-2 at a garage sale thinking about getting started in HO. The loco runs, but a little spotty, so I decided to figure out how to open it and try cleaning and oiling it. After I figured that out I saw three electrical connections on the back where the engineer would be. My son said maybe it's dcc ready, whatever that is. He looked at the bottom of the tender and found it had hole in it for speakers but he can't figure out how to open it. Can someone look at the pictures and tell me what I have and what the electrical connections are for? I tried looking at the pictures of 2-8-2's in the parts and diagram sections and don't see anything that helps. The last train I had was 67 years ago.
I've tried for over an hour to post pictures without any luck,I don't understand the process here I guess.
What I have is a 2-8-2 that has 3 electrical prongs coming out of the back of the loco, the are not round, they are flat. Any ideas?
