Above is a copy of an ad for Revell's N-scale Rapido line of model trains.
Following their exit from the HO-scale market in the '60s, Revell returned to trains in the smaller N-scale in the late '60s.
Revell did issue some the structure kit line again in 1977. Revell-Monogram in the '70s produced
a series of static HO-scale plastic steam engine kits.
As happens frequently in the hobby world, the molds for the Revell line did not collect dust for long.
Con-Cor in more recent times has issued numerous items from the former Revell HO-scale train line. Con-Cor re-issued
the Revell SW-7 diesel switcher. The SW-7 model from Con-Cor even has examples powered with a drive mechanism produced
by Kato of Japan. In the late 1980s, Con-Cor had an announcement in their Trainalog product catalog that stated an F-7A
was coming in 1989. The catalog includes a picture of a collection of F-units lined up, all appear to be custom decorated
Athearn models, with one F-3A in Union Pacific dress standing before the group. The F-3A looks to be Model Power's clone
of the old Cox tooling. To my knowledge Con-Cor never issued this promised F-7A, but one could assume it might have
been the former Revell tooling.
Some of the Revell freight cars survived into Con-Cor's line of products, as did the Operating Hopper
and many of Revell's structure kits originally produced for the train line.
