Backstory
After the disappointing performance of the YAFR (Yet Another Fictional Railroad) Class-1, a junior engine designer came to the brilliant conclusion that the solution was more power. With the help of some other like-minded designers, they appropriated a Class-1 and extensively modified it into what became known as the Class-2. As a so-called Super-Garratt, the Class-2 had all the power anyone could desire, and then some. Unfortunately, those designers failed to realize that "eventually" was insufficient for the scheduling of freight service, even when bringing all the freight at once, and the Class-2 was quickly relegated to ultra-heavy shunting duty.
