São Paulo Railway I 60 to 69

The British-controlled São Paulo Railway procured ten Consolidation freight locomotives in 1909, designed by chief engineer Charles H. Fox and manufactured by the North British Locomotive Company in Glasgow. Originally, they had got non-continuous numbers between 6 and 91. Later they were renumbered I 60 to I 69.

The tracks, which were very good by South American standards, allowed a heavy locomotive with an axle load of 16 and a half tons. Thus, a generously dimensioned boiler with Belpaire firebox is evident at the first glance. A Schmidt-type superheater was used, which was not standard on British locomotives at the time. Likewise, they had a steam reverser and there were special bypass valves between the cylinders, which reduced the back pressure when coasting with the regulator closed.
