Class 433AA 3-Cylinder
Heavy Shunting Locomotive
Designed by Bela Šahlmeti
Built by Robert Stephenson & Co., Newcastle-on-Tyne, England, in 1928
The class 433AA shown above was, in fact, the original design. In the event only four were built before the switch to bar frames.
Despite the shadow hanging over his job from the dispute over the 434A, Šahlmeti had started to experiment with livery variations as well, the other three 433AAs being delivered as shown below.
