Specification
Weighing 39.5 long tons (40.1 t; 44.2 short tons) with a tender of 27.4 long tons (27.8 t; 30.7 short tons), they could haul express trains easily at 50 miles per hour (80 km/h) in suitable parts of the country. With huge (for the period) 58 inches (1,473 mm) coupled driving wheels, a working steam pressure of 185 pounds per square inch (1,276 kPa), and 16.5 inches (419 mm) diameter cylinders with 22 inches (559 mm) piston strokes, the handsome "Ud"s were more than capable of making up lost time with mile-a-minute runs as recalled with pride by old Manawatu railway employees.
Withdrawal
However, fast and powerful as they were the "Ud"s were unable to survive the standardisation program between 1925 and 1935 and were written off in 1929.
