The South African type XM1 tender was a steam locomotive tender.

Contents

Type XM1 tenders were Type TM tenders which were reclassified after their intermediate draw and buffing gear were altered to an "X_" tender configuration. They first entered service in 1912, as tenders to the SAR Class MC 2-6-6-0 Denver type Mallet locomotive. [1] [2] [3]

The South African type TM tender was a steam locomotive tender from the pre-Union era in the Natal Colony.

The South African Railways Class MC 2-6-6-0 of 1912 was a steam locomotive.

Origin

Type TM tenders were built between 1910 and 1912 by the North British Locomotive Company (NBL). The two Type XM1 tenders originally entered service on the South African Railways (SAR) in 1912, as Type TM tenders to Class MC 2-6-6-0 Denver type Mallet locomotives. [1] [2] [3] [4] [5]

North British Locomotive Company defunct British locomotive manufacturer, active 1903–1962

The North British Locomotive Company was created in 1903 through the merger of three Glasgow locomotive manufacturing companies; Sharp, Stewart and Company, Neilson, Reid and Company and Dübs and Company, creating the largest locomotive manufacturing company in Europe and the British Empire.

Rebuilding

At some stage before 1941, the intermediate draw and buffing gear of two of the tenders, numbers 1607 and 1615, were altered to an "X_" tender configuration. These two tenders were reclassified to Type XM1. [3]

Characteristics

The tender had a coal capacity of 8 long tons 5 hundredweight (8.4 tonnes) and a water capacity of 4,000 imperial gallons (18,200 litres), with a maximum axle load of 10 long tons 18 hundredweight (11,070 kilograms). [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 "X_" tenders could be used with the following locomotive classes: [3]

South African Class 4 4-8-2 class of 2 South African 4-8-2 locomotives

The South African Railways Class 4 4-8-2 of 1911 was a steam locomotive from the pre-Union era in the Cape of Good Hope.

South African Class 4A 4-8-2 class of 10 South African 4-8-2 locomotives

The South African Railways Class 4A 4-8-2 of 1913 was a steam locomotive.

South African Class 5 4-6-2 class of 4 South African 4-6-2 locomotives

The South African Railways Class 5 4-6-2 of 1912 was a steam locomotive.

The second letter indicates the tender's water capacity. The "_M" tenders had a capacity of 4,000 imperial gallons (18,200 litres; 4,800 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]
