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

Contents

The Type LP tender first entered service in 1918, as tenders to the Classes 14C, 15B and MJ1 steam locomotives which were acquired by the South African Railways from Canada in that year. [1] [2] [3]

South African Class 14C list of locomotives with the same or similar names

The South African Railways Class 14C includes four batches of the same locomotive type, all initially designated Class 14C. Through reboilerings, rebalancings and cylinder bushings during its service life, this single class eventually ended up as six distinct locomotive classes with two boiler types and a multitude of axle load and boiler pressure configurations.

South African Class 15B 4-8-2 class of 30 South African 4-8-2 locomotives

The South African Railways Class 15B 4-8-2 of 1918 was a steam locomotive.

The South African Railways Class MJ1 2-6-6-0 of 1918 was a steam locomotive.

Manufacturer

Type LP tenders were built between 1918 and 1922 by Montreal Locomotive Works in Canada. [1]

Montreal Locomotive Works defunct Canadian locomotive manufacturer

Montreal Locomotive Works (MLW) was a Canadian railway locomotive manufacturer which existed under several names from 1883 to 1985, producing both steam and diesel locomotives. For a number of years it was a subsidiary of the American Locomotive Company. MLW's headquarters and manufacturing facilities were located in Montreal, Quebec.

The South African Railways (SAR) placed eight Class MJ1 2-6-6-0 Mallet, 73 Class 14C 4-8-2 Mountain and thirty Class 15B 4-8-2 Mountain type locomotives in service between 1918 and 1922. The locomotives and tender were designed by Montreal Locomotive Works, to the specifications of D.A. Hendrie, Chief Mechanical Engineer of the SAR. The Type LP tender entered service as tenders to these three locomotive classes. [1] [2] [3] [4]

Characteristics

As built, the tender had a coal capacity of 10 long tons (10.2 tonnes) and a water capacity of 4,250 imperial gallons (19,300 litres), with an average maximum axle load of 12 long tons 14 hundredweight 2 quarters (12,930 kilograms). [1] [2] [3] [4]

Locomotives

Only the Classes MJ1, 14C and 15B were delivered new with Type LP tenders, which were numbered for their engines in the number ranges as shown. An oval number plate, bearing the engine number and often also the tender type, was attached to the rear end of the tender. [1] [3]

South African Class 14C 4-8-2, 1st batch class of 20 South African 4-8-2 locomotives

The South African Railways Class 14C 4-8-2 of 1918 was a steam locomotive.

South African Class 14C 4-8-2, 2nd batch class of 20 South African 4-8-2 locomotives

The South African Railways Class 14C 4-8-2 of 1919 was a steam locomotive.

South African Class 14C 4-8-2, 3rd batch class of 20 South African 4-8-2 locomotives

The South African Railways Class 14C 4-8-2 of 1919 was a steam locomotive.

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 "L_" tenders could only be used with the three locomotive classes with which they were delivered. [2] [3]

The second letter indicates the tender's water capacity. The "_P" tenders had a capacity of 4,250 imperial gallons (19,300 litres; 5,100 US gallons). [3]

Modifications

Most of these tenders were later modified by shortening and raising the upper sides of the coal bunker, in effect making the coal at the rear of the bunker more easily accessible to the stoker and apparently without affecting the tender's coal capacity. [3]
