Although the Franklin Institute displays this engine as typical of American steam locomotives it is actually a very odd duck.  It's a three cylinder compound with a watertube boiler and it was built to serve as a demonstrator for Baldwin.  They sent it all around the country for the various railroads to consider but what it mostly did was to warn the railroads not to abandon fire tube boilers and to beware of the complexity and inaccesability of the third cylinder.  Only Union Pacific and Southern Pacific went ahead and ordered locomotives on this pattern and even these had the conventional firetube boiler.  Southern Pacific's engines were 4-10-2's like the Franklin Institute engine while the Union Pacific built a 4-12-2 which is now available as a model by Mike's Train House.  The Union Pacific monster was roughly equivalent to a 4-6-6-4 Challenger but the Challenger was more flexible and had wider route availability
