Recently bought another favorite of mine; a Lionel 2025 Loco from 1947. It just needed a clean and lube and new brushes tune up, it was in very good shape.
I have a 4x8 layout of O27 gauge track and all O27 curves. Have about 45 feet of total track.
This 2025 is just a strong puller even without magna-traction. It surprised me. Just recently bought enough cars to test it. All postwar Lionel cars. It's pulling 15 cars in the consist.
What a beast. Its in better shape than I am.
