Penrose

Penrose is an 0-4-2ST Kerr Stuart Tattoo Class, found At Ruston Narrow Gauge Shed Alongside Lily, and Bella.

Appearance
Penrose is a Kerr Stuart "Tattoo" 0-4-2ST. They are painted in a maroon red with gold and black lining, black wheels and red side rods. Penrose has buffers instead of blocks or nothing at all like most of her real life counterparts. Penrose is one of the few locomotives with full valve gear (Hacksworth Valve Gear). Penrose's coal bunkers are located behind their saddle tank. They also have a lamp mounted on top of their smokebox.

Trivia

 * Penrose is one of three narrow gauge engines to have fully modeled and working valve gear (Griffin, and Friend being the other two, each having a different valve gear)
 * Penrose is the only narrow gauge locomotive at Ruston to not be in the original game (Taleland Railway 2,0) Bella and Lily having been in the original game.
 * Penrose is the only engine in game whose performance is based on the speed notches. On inclines, she has been known to wheelslip vigorously, causing her to stall. However, when less speed is applied, her wheels will grip to the rails properly, allowing her to continue.
