Thanks everyone!
Luvin,
I did not sacrifice a engine, I bought the pilots directly from the Lionels replacement parts website. Click here to see page. I ordered parts number 22 and 23 which are the front and rear pilots you can see from the exploded parts picture. This one is from a Burlington Northern SD40 but others like Conrail or Chessie would have worked as well. I'm very impressed with their parts website.
David1,
I will be tearing down the Black Diamond Railway within a year or two and rebuilding from scratch. I will try to extract the urban elevated trestle section and make and sell a small layout with it. Otherwise everything will be scrapped for parts. I'm going to open up the wall to expand and gain viewing access from the other side.
Joe,
I know, its wrong, but I had no choice.
