I was missing around my layout this after noon and I got a wild hair to see how many cars my Bachman 10 wheeler could pull. My layout is 10.5 by 19 feet long. I used my Lionel cars and started with my passenger cars (4) and 1 flat. I ended the session at 14 total cars and can still go for a few more. By the way the total train length is 17 ft at this time.
This evening I ended up with 17 cars before my 10 wheeler started sliping. Next I attached my C&A 4-6-4 to the cars and it was at it's limit. Okay. my Lionel torpedo was the next victim. Same results. Next up is my Atlas SW6 switch engine. No hesitation, it had no problems with the 17 cars. By the way, the drag was 21 feet. Now I am going to have to get some more cars for the SW to pull.
