Did MTH produce 18" Aluminum cars?

MTH produced smooth side and ribbed side aluminum 18" passenger cars, but none with interiors.  Their 18" aluminum cars incorporated the "silhouette" window strips.

Here are a couple of photos - Nice cars but I don't think these are the aluminum ones you mention are they RockyRoad?   I'm thinking of Weaver's nice longer aluminum cars that were smooth with smooth roofs as well and not much detail.

Notice in the last photo that the MTH box does not say 'Aluminum' but the dealer-added sticker does.  Not a deception as this was taken from the MTH website however that I included in the original post.

Sam, I'd guess you are seeing catalog writer text copying as that set was right when they changed from extruded aluminum to molded bodies. The 20-6612 set doesn't say aluminum, nor does the 5 car B&O 20-6513 set.

If you do a search on the MTH "Product Locator" and enter... 70' aluminum passenger cars...a number of road names will be listed. The NYC shows a ribbed set and there are a number of painted smooth side 70'. I believe the NYC is also plated.

YEs. Mid 1990's the Aluminum 70' sets came to play... abet with silhouettes and no interiors. I don't believe MTH did Aluminum with interiors though. I have the PRR Smooth side 5 car set with the 2 pack addition that I recently purchased last year at an auction house.

One clue Sam is to look at the roof. Aluminum cars are extruded. You couldn't have transverse ribs on an extrusion unless they were somehow added on. Not economical to do this.

Just grab the bottom of one of the "skirts" on the bottom of the shell with your index finger and thumb, and try to bend it out slightly. If it bends slightly, it's plastic. Aluminum skirts won't bend.
