History

The history of the locomotives starts in 1932, when to cope with increased traffic levels, Marc de Caso designed a new class of 2-10-0 Decapod locomotives: the 5.1200s, later to become the SNCF 2-150.B.

In order to increase standardisation, and to reduce operating and maintenance costs, the 5.1200s shared many parts with the third series of Super Pacifics (3.1251 to 3.1290) and the suburban Mikado tank locomotives (4.1200 to 4.1272).[1]

Construction

The class was built between 1933 and 1935 by the Nord's workshops at La Chapelle and Hellemmes-Lille.

Description

Locomotive

The 5.1200s had the same boiler as the Super Pacifics; the Belpaire firebox was riveted and made of copper. The front end, consisting of four cylinders, was a steel monobloc casting.[2][3]

Originally, they were hand-fired, but the coal consumption was such that in 1934, 10 locomotives of the class were fitted with mechanical stokers. The results were so successful, that the remainder of the class was later equipped as well.

Tenders

The 5.1200s were equipped with type 38.A tenders at the start of their career. Some had type 37.A; while later some were coupled to type 36.A

Livery

The 5.1200s were delivered in the Nord's standard livery of chocolate brown with yellow lining; bufferbeams were red, edged in white. This livery was applied to all of the company's compound locomotives.

After nationalisation in 1938, the SNCF livery – No.306 exterior green and black with yellow lining – was gradually applied. The locomotives did not carry the SNCF's standard cabside number plates, but had the details painted on, which was standard practice on the Région Nord.

Models

The 5.1200s have been modelled in O scale by the Swiss company Lemaco.
