The South African type MT2 tender was a steam locomotive tender.

Contents

Type MT2 tenders were modified Type MT tenders with enlarged coal bunkers. The original Type MT tenders entered service on the South African Railways between 1928 and 1945. [1] [2] [3]

Origin

Type MT tenders were built between 1928 and 1945 by Berliner Maschinenbau, Borsig Lokomotiv Werke, Henschel and Son, Friedrich Krupp AG, North British Locomotive Company, Robert Stephenson and Hawthorns, and Škoda Works as tenders to the Classes 12A, 19B, 19C and 19D 4-8-2 Mountain type steam locomotives which were placed in service by the South African Railways during that period. [1] [2] [3]

Between 1945 and 1948, several of these tenders were reclassified to Type MT2 after being modified to increase their coal capacity by extending the top of the coal bunker rearwards. [2] [3]

Characteristics

The rebuilt tender had a coal capacity which had been increased from 12 long tons (12.2 tonnes) to 14 long tons (14.2 tonnes). Its water capacity remained the same. [2] [3]

Classification letters

Since many tender types are interchangeable between different locomotive classes and types, a tender classification system was adopted by the SAR. The first letter of the tender type indicates the classes of engines to which it could be coupled. The "M_" tenders could be used with the locomotive classes as shown, although engine drawbars and intermediate emergency chains had to be replaced or adjusted to suit the target locomotive in some cases. [3]

The second letter indicates the tender's water capacity. The "_T" tenders had a capacity of between 5,587 and 6,000 imperial gallons (25,400 and 27,300 litres; 6,710 and 7,210 US gallons). [3]

A number, when added after the letter code, indicates differences between similar tender types, such as function, wheelbase or coal bunker capacity. [3]
