Reply to "O-36 Corrugated Auto Carrier Cars"

I was just about to say what Mike has now mentioned. 

The MTH units are full 1:48 scale and, as a result, too large for my layout. However, I wasn't aware that the Lionel versions were even larger. 

I've had no luck finding slightly smaller cars anywhere, and it's a real shame considering how common this type of rolling stock is on the rails thes these days.
