[3] When the need arose, the coal capacity of tenders was sometimes increased by makeshift means, such as constructing wooden extensions for the bunker sides.
In the example depicted, the Cape of Good Hope Governor's train is shown arriving in Fort Beaufort behind CGR 7th Class no.
The engine's Type ZC tender's sides had been raised by installing what appears to be planking, to allow a greater coal load.
In addition, an open gondola-type goods truck between the tender and the passenger carriage is loaded with more coal and two workmen.
These rebuilt tenders had a more modern appearance with flush sides all the way to the top of the coal bunker.
[2][3][5] The program to rebuild several older tender types with new upper structures was begun by Col F.R.
Collins DSO, who approved several of the detailed drawings for the work during his term in office as Chief Mechanical Engineer of the SAR from 1922 to 1929.
