IHC makes em, also Branchline Trains (I think) makes a heavy weight pullman kit with three differrent #s. I have all three of em and one of these days I'll get around to putting them together. I don't think Rivarossi has made them in C.N. for a couple of years now. Years ago E & B Valley R.R. Co. sold their "American Flier" type coach kit painted for C.N. and these may still be available at train shows. (I have quite a few of these kits waiting to be put together, not all C.N. though)  P.M.

Motor Max also has nice, modern, tractor trailer trucks in their Big Rigs series that are either H.O. scale or close. they sell for the reasonable price of $2.99 at my local Maxi Drugs store.   P.M.
