The South African type MY1 tender was a steam locomotive tender.

Tender (rail) vehicle for carrying a steam locomotives supply of fuel and water

A tender or coal-car is a special rail vehicle hauled by a steam locomotive containing its fuel and water. Steam locomotives consume large quantities of water compared to the quantity of fuel, so their tenders are necessary to keep them running over long distances. A locomotive that pulls a tender is called a tender locomotive. Locomotives that do not have tenders and carry all their fuel and water on board the locomotive (itself) instead are called tank locomotives.

Type MY1 tenders entered service in 1952 and 1953, as tenders to the Class S2 0-8-0 shunting steam locomotives which entered service on the South African Railways in those years. [1] [2] [3] [4]

The South African Railways Class S2 0-8-0 of 1952 was a steam locomotive.

Manufacturer

Type MY1 tenders were built in 1952 and 1953 by Friedrich Krupp AG of Essen in Germany. [1]

Krupp German family dynasty

The Krupp family, a prominent 400-year-old German dynasty from Essen, became famous for their production of steel, artillery, ammunition, and other armaments. The family business, known as Friedrich Krupp AG, was the largest company in Europe at the beginning of the 20th century. It was important to weapons development and production in both world wars. One of the most powerful dynasties in European history, for 400 years Krupp flourished as the premier weapons manufacturer for Germany. From the Thirty Years' War until the end of the Second World War, they produced everything from battleships, U-boats, tanks, howitzers, guns, utilities, and hundreds of other commodities.

Essen Place in North Rhine-Westphalia, Germany

Essen is the central and second largest city of the Ruhr, the largest urban area in Germany. Its population of 583,393 makes it the ninth largest city of Germany, as well as the fourth largest city of the federal state of North Rhine-Westphalia. On the Ruhr and Emscher rivers, Essen geographically is part of the Rhineland and the larger Rhine-Ruhr Metropolitan Region. The Ruhrdeutsch regiolect spoken in the region has strong influences of both Low German (Westphalian) and Low Franconian.

The Class S2 0-8-0 steam locomotive was designed by L.C. Grubb, Chief Mechanical Engineer of the South African Railways (SAR) from 1949 to 1954, as a shunting locomotive with a light axle load for harbour work where most of the trackwork was laid with light rail. The Type MY1 entered service as tenders to these locomotives. [1]

Characteristics

The tender had a coal capacity of 8 long tons (8.1 tonnes), a water capacity of 4,200 imperial gallons (19,100 litres) and a maximum axle loading of 8 long tons 18 hundredweight 2 quarters (9,068 kilograms). It was a tank wagon type tender with a cylindrical water tank, similar in appearance to the North American Vanderbilt type tender. The SAR's Types MX, MY and MY1 tenders with their cylindrical water tanks all became commonly known as Torpedo tenders. [1] [2] [3] [4]

Like the Type CL, Type MX and Type MY tenders, it rode on three-axle Buckeye bogies to reduce the axle load. [1] [2] [3] [4]

South African type MY tender

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

While the tender was similar in general appearance and dimensions and had the same wheelbase as the Type MY tender of the Class 24, it had a different coal bunker top design. As was done with the tenders of the Classes S and S1 shunting locomotives, the top sides of the coal bunker were scalloped out to improve the crew's rearward field of vision. [2] [3] [4]

Locomotive

Only the Class S2 locomotives were delivered new with Type MY1 tenders, which were numbered in the range from 3701 to 3800 for their engines. An oval number plate, bearing the engine number and often also the tender type, was attached to the rear end of the tenders. [1] [3] [4]

Most of the Class S2 locomotives were placed in shunting service in the Durban, Table Bay and Port Elizabeth harbours, while some were also allocated to yards on the Witwatersrand and in the Eastern Transvaal. [2] [5]

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 in some cases, engine drawbars and intermediate emergency chains had to be replaced or adjusted to suit the target locomotive. [3] [4]

The second letter indicates the tender's water capacity, while a number, when added after the letter code, indicates differences between similar tender types, such as function, wheelbase or coal bunker capacity. The "_Y1" tenders had a capacity of 4,200 imperial gallons (19,100 litres; 5,040 US gallons). [3] [4]
