Today while surfing the internet I came across a wikipedia article about a Pennsylvania Railroad S1 Class Steam Locomotive which bears a resemblance to the Number Nine from Grim Fandango.
According to the article, it was the only one of its kind ever to be built, it was the largest express passenger locomotive ever constructed, and its steel locomotive bed was the largest ever made.
Its boiler was the largest the Pennsylvania Railroad had ever constructed and the locomotive itself was so huge it could not fit most of the PRR system and had to be restricted to the mainline.
Its service life wasn't very long and only lasted from 1939 till 1945, its goal of hauling a 1000 tons at 100mph was not reached, and its extreme length made the locomotive incapable of negotiating curves on most lines of PRR track, for this reason, no further S1's were constructed.
Here is a picture of the locomotive at the World's Fair in New York in 1939. Any thoughts?

I can only hope this hasn't been found out already
