My inner 8 year old is jumping up and down. My 50+ outer adult says you just made the case for can motors and LED lights.
Oh yeah. I have nine Warbonnett F3s, with not a can motor among them, and a total of fifteen incandescent lighted cars. I have resisted buying a good modern set for some time hoping Lionel would offer a Vision Super Chief set - smoke unit and speaker in every unit, etc., but I suppose it's time to bit the bullet and buy something modern enough. And I should get off my duff and convert the cars to LEDs.
It's either that or buy stock in the local utility company.
After my experience at the mall, I gave up on anything that doesn't have can motors, both for the current draw and reliability aspects. I too want to convert my passenger cars to LED lighting, but I want to get the layout done first.
