The former East German test locomotive 18 201, just like the 05 002, has giant driving wheels 2300 mm (= 7 ft 6.55 in = 90.55 in) in diameter, vs. the 2000 mm norm of other German (or French) express steam locomotives.
The Mallard, too, had wheels of just 2032 mm (= 6 ft 8 in = 80 in) - like most other British or American fast steamers -, while both the class A and F7 "Hiawathas" (and the PRR S1) had 2133.6 mm (= 7 ft = 84 in) wheels. *Traitor*, n.
