"Challenger" engine, "Challenger" diner: Coincidence or connection? You decide ...
The tight connection between streamliner/moderne train design and contemporary diner architecture is so obvious that it's undeniable. But here's another one to ponder: From 1936 to 1944, ALCO built an articulated steam engine for the Union Pacific called the "Challenger". Maybe you have a model of one? Mid-way into production, in 1941, the New Jersey-based Kullman Dining Car [read: diner] Company introduced a new "Challenger" diner model that featured Streamline Art Deco styling.
These diners had monitor roofs -- like a rail car, but without windows in them; and they had glass block entrances and corners, and blue enamel sides, among other things. The glass block building material obviously would not be suited for a rail car or trolley, and so it is a clear departure. These buildings also appear wider than earlier diner buildings during a time when streamlined cars became narrower. But the monitor roof remained, even though it was no longer functional for light and ventilation. (Note, however, the side vents in the photos below -- probably better suited for a restaurant.)
So, the evidence of a deliberate connection between the two "Challenger" models is less compelling than it is for the more prolific uses of the names "Streamliner" and "Flyer" across trains and restaurants. But it is possible that a deliberate connection was intended. According to the Wikipedia article on Kullman, in 2000, the company introduced a "Blue Comet" model, referring of course to the Central of New Jersey train. (See the previous reply about the Blue Comet rail car that is now part of a restaurant.)
Following are two examples of the Challenger model, both from Providence, RI that I photographed in 2000. Unfortunately, the glass block entrances are not visible. At one time both were endangered; now only one is:
1946 Silver Top (rotting away in Pawtucket since 2002 and up for auction on 5 Oct. -- three days away!)
1948 El Faro (now the West Side Diner and at a new location in Providence)
