 Pacific wheel arrangement in passenger train service.

Manufacturer

The Class 16B 4-6-2 Pacific locomotive was designed by D.A. Hendrie, Chief Mechanical Engineer (CME) of the South African Railways (SAR) from 1910 to 1922, and built by the North British Locomotive Company

 in most respects, except that they had wider cabs than the Class 16 while the Class 16C was equipped with a combustion chamber in the firebox.

Watson Standard boilers

During the 1930s many serving locomotives were reboilered with a standard boiler type designed by A.G. Watson, CME of the SAR from 1929 to 1936, as part of his standardisation policy. Such Watson Standard reboilered locomotives were reclassified by adding an "R" suffix to their classification.

Eventually all ten Class 16B locomotives as well as all thirty Class 16C locomotives were reboilered with Watson Standard no 2B boilers. In the process of reboilering the main difference between the Class 16B and Class 16C, Hendrie’s combustion chamber behind the Class 16C boiler, disappeared and the reboilered Class 16B locomotives were also reclassified to Class 16CR. Early conversions were equipped with copper and later conversions with steel fireboxes. In the process they were also equipped with Watson cabs, with their distinctive slanted fronts compared to the conventional vertical fronts of their original cabs.

Some ex Class 16B locomotives did, however, erroneously receive new number plates after reboilering identifying them as Class 16BR, even though such an SAR Class never officially existed.

An obvious visual difference between an original and a Watson Standard reboilered locomotive is usually a rectangular regulator cover just to the rear of the chimney on the reboilered locomotive. In the case of the Class 16B and Class 16CR two even more obvious visual differences are the Watson cab and the absence of the Belpaire firebox hump between the cab and boiler on the reboilered locomotives.

Ben Schoeman

Of the Class 16B locomotives, number 805 has some claim to fame, since long time South African Minister of Transport Ben Schoeman started his Railway career at Braamfontein as a stoker on this locomotive during the 1930s.

When number 805 was withdrawn from service, reboilered and reclassified to Class 16CR by then, this locomotive was actually dereboilered to its original Class 16B condition. A dummy boiler that looked like the original boiler with its Belpaire firebox was fabricated and installed and it was refitted with an original wide Hendrie cab that was found dumped at the old Pretoria Mechanical Workshops.

It was then plinthed outside Johannesburg station on 18 and 19 March 1974, the work taking two days to complete. The Minister of Transport, the Hon. B.J. Schoeman, unveiled the commemorative plaque during a ceremony on 1 July 1974.

In the early 1990s the locomotive was removed from Johannesburg station to be exhibited in the Outeniqua Transport Museum
