„ref.PLT 12/1/25/4“ vom 27. Dezember 1973: "Modification of class 25 locomotive to non-condensing
Locomotive no.3468 was converted from a condensing to a non-condensing type during heavy repairs at Salt River.
The cost of a subsequent heavy repair will be less than the heavy repair cost of an unmodified class 25 locomotive though the saving will not be substantial. (This applies to the locomotive only).
The cost of a subsequent heavy repair on a modified tender on the other hand will be approximately R 7.000 less than the heavy repair cost on an unmodified tender.
Further, according to the latest available figures, the annual average expenditure in Transportation only on class 25 and class 25NC locomotives is R 16.937,00 and R 8.400,00 respectively. It is thus reasonable to deduce that conversion will result in a saving in transportation of more than R 8.000 per locomotive per annum. Although the class 25 condensing locomotive consumes considerably less water, and probably also somewhat less coal than the class 25NC, this saving is no doubt offset by relatively frequent failures experienced with the condensing equipment, resulting in reduced availability of the condensing locomotives. Further factors which offset the saving gained by a class 25 condensing locomotive over a class 25NC are difficulties experienced in the purchase and manufacture, repair and transportation of the sophisticated condenser spares.
Provided conversion is carried out during heavy repairs the modification will cost approximately R3000, and as this amount will be recovered in a very short time, as can be seen above, your authority is sought to convert all class 25 (condensing) locomotives to non condensing
operation as they undergo heavy repairs.”
Hi Stefan
You are right, that was one of the first conversions. There were about 3 different models converted and they decided on the one they finally ended with. Why they had those ugly first ones I do not know.
The loco number could be anything as the tenders were swapped around between locos (ex 25s and NCs)
I don't believe even the frames kept their original numbers in the last 10 years or so of steam so any number could be on any loco or frame or tender.
Catch you later

Die ersten 25, welche auf 25NC umgerüstet wurden, waren 25 3468 und der NBL-Erstling 25 3452. Bei diesen beiden Loks wurden an den Tendern nur die Kondensatoren durch Stahlplatten ersetzt, die Turbinen entfernt und die originale Form des Kondenstenders beibehalten, ohne den Wasservorrat zu erhöhen: Dieser Umbau war wegen der geringen Wasservorräte im Original-Behälter des Tenders kaum praktikabel, aber die beiden Loks behielten noch Ihr übliches Aussehen. Bei einem späteren Aufenthalt im Ausbesserungswerk Salt River wurden sie im Laufe des Jahres 1975 in die endgültige Form mit der umgekehrten Badewanne mit vergrößertem Wasservorrat, welche ab der 25 3487 und 25 3512 angewandt wurde, umgebaut.
