And a few other bits.
I made some DZ and B wagons, 2ft gauge however they have Welsh Highland branding, As in WHR instead of SAR, can be reskined by anyone if required.
Bit confusing with SAR applying to different countries, can't say I've seen any cape gauge South African stuff, leastwise not on the DLS, may be wrong though!
