Being only a dabbler in O scale (small garden layout) I not really au fait with what's available. I'm wondering have there ever been Heavyweight cars made for 2 rail that weren't highly expensive brass ones ? Simon
The answer is yes. Try an oogle Google search and see what pops up. Try "O Scale Heavyweight Passenger Cars". You'l like what you find...I quarantee it.
Here's a link to Lionel's online catalogs: Lionel Products In the signature catalog there are a number of heavyweight sets, and individual cars with sound, in the passenger car pages. Best!
