The largest steam locomotive built in Europe was a 4-8-2+2-8-4 Garratt, built by Beyer, Peacock and Company for the Soviet Railways in 1932. The most numerous Garratt class in the world was also a Double Mountain, the Class GMA and GMAM of the South African Railways, of which 120 were built between 1954 and 1958.
The 2-8-8-8-4 was considered unsuccessful because it only made a maximum speed of 4.8–8.0 km/h (3–5 mph) and had high maintenance costs. The XA was sent back to Baldwin Locomotive Works where it was taken apart in 1920 and converted into a 2-8-8-0 and a 2-8-2. These two engines were in service until 1953. [3]

This was equal to 17.3 inches (440 mm) of vertical belt armor at 19,000 yards (9.4 nmi; 17 km). The belt armor extended to the triple bottom with a Class B homogeneous Krupp-type lower belt and tapered from its maximum thickness of 12.2 inches (310 mm) down to 1 inch (25 mm) at the lowest portion at the triple bottom.
The ship had an overall length of 591 ft 6 in (180.3 m), a beam of 61 ft 10 in (18.8 m) and a draught of 17 feet 7 inches (5.4 m). She was powered by four geared steam turbine sets, each driving one shaft, which developed a total of 75,000 shp (56,000 kW ) and gave a maximum speed of 32 kn (59 km/h; 37 mph). [ 4 ]
