The South African type CL tender was a condensing steam locomotive tender.
The single Type CL condensing tender entered service in 1950 as tender to the modified Class 20 2-10-2 Santa Fe type experimental condensing steam locomotive. [1] [2]
The South African Railways Class 20 2-10-2 of 1935 was a steam locomotive.
The Type CL tender was built by Henschel and Son with works number T28388. In 1950, the South African Railways (SAR) modified its sole Class 20 locomotive to an experimental condensing locomotive equipped with this condensing tender which had been ordered from Henschel in 1948. [1] [3] [4] [5]
Henschel & Son was a German company, located in Kassel, best known during the 20th century as a maker of transportation equipment, including locomotives, trucks, buses and trolleybuses, and armoured fighting vehicles and weapons.
The tender was designed for a Deutsche Reichsbahn Class 52 condensing locomotive. It was modified slightly and was equipped with a pair of Buckeye three-axle bogies instead of the German arrangement of one six-wheeled and one four-wheeled bogie. It had an 11 long tons (11.2 tonnes) coal capacity, a 3,900 imperial gallons (17,700 litres; 4,680 US gallons) water capacity which included the underbelly condensate tank, and a 13 long tons 17 hundredweight 3 quarters (14,110 kilograms) maximum axle load. The tender was capable of condensing 27,000 pounds (12,000 kilograms) of exhaust steam per hour in maximum operating temperatures of between 100 and 110 degrees Fahrenheit (38 and 43 degrees Celsius). The tender had six large radiators on each side, cooled by three exhaust steam-driven roof-mounted fans which drew air from outside through the radiators. [1] [3] [4] [5] [6] [7] [8]
The Deutsche Reichsbahn, also known as the German National Railway, the German State Railway, German Reich Railway, and the German Imperial Railway, was the name of the German national railway system created after the end of World War I from the regional railways of the individual states of the German Empire. The Deutsche Reichsbahn has been described as "the largest enterprise in the capitalist world in the years between 1920 and 1932", nevertheless its importance "arises primarily from the fact that the Reichsbahn was at the center of events in a period of great turmoil in German history."
The Deutsche Reichsbahn's Class 52 is a German steam locomotive built in large numbers during the Second World War. It was the most produced type of the so-called Kriegslokomotiven or Kriegsloks. The Class 52 was a wartime development of the pre-war DRG Class 50, using fewer parts and less expensive materials to speed production. They were designed by Richard Wagner who was Chief Engineer of the Central Design Office at the Locomotive Standards Bureau of the DRG. About a dozen classes of locomotive were referred to as Kriegslokomotiven, however the three main classes were the Class 52, 50 and 42.
Only the modified Class 20 locomotive ran with the Type CL tender. The tender was designed in such a way that it could also be used on a modified Class 19D or Class 24 locomotive, but such modifications never took place. [1] [5]
The South African Railways Class 19D 4-8-2 of 1937 was a steam locomotive.
The South African Railways Class 24 2-8-4 of 1949 is a steam locomotive.
During trials, a saving of between 88% and 93% on water as well as a lower coal consumption were attained, the latter brought about by the higher temperature of the feedwater condensate. Depending on the operating conditions, a water range of between 400 and 680 miles (640 and 1,090 kilometres) was achieved. The positive results of the condensing trials led to the introduction of the Class 25 4-8-4 condensing locomotive fleet between 1953 and 1955. [1] [4] [5] [8]
The South African Railways Class 25 4-8-4 of 1953 was a condensing steam locomotive.
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 can be coupled. The two "C_" tender types were condensing tenders and could only be used with the specific locomotive class for which each was designed. [1] [5] [9]
The second letter indicates the tender's water capacity. The "_L" tenders had a capacity of 3,900 imperial gallons (17,700 litres; 4,680 US gallons). [9]
The South African Railways Class 25NC 4-8-4 of 1953 was a steam locomotive.
The South African Railways Class 21 2-10-4 of 1937 was a steam locomotive.
The South African Railways Class 18 2-10-2 of 1927 was a steam locomotive.
