Nord 4.1201 to 4.1272 was a class of French Mikado tank locomotives built for suburban service on the Chemin de fer du Nord's lines that are north of Paris.

Construction history

The 72 locomotives were built from 1932 until 1935 by seven manufacturers, including the railway's own workshops at Hellemmes, Lille

From 1936, as an economy measure, the boiler pressure was reduced from 1.8 to 1.6 megapascals (260 to 230 lbf/in²), and the cylinder bore was reduced from 640 to 585 millimetres (25.20 to 23.03 in). This reduced the tractive effort from 266.37 to 197.38 kilonewtons (59,880 to 44,370 lbf).

Service history

In 1935, the 4.1200s essentially provide commuter services at the head of push-pull trains composed of five to nine cars, up to 420 tons gross. They are assigned in part to depots of Joncherolles [ fr ], Mitry, Beaumont ... They are found between Paris on the one hand and Ermont, Creil and Pontoise on the other. In addition to the commuter traffic, 4.1200's also take charge of the freight service between Persian-Beaumont and Luzarches with reversal at Montsoult.

The beginning of the end began in 1969 and the last two trains to have been powered by 2-141.TC ran on December 12, 1970, with train 1731 between Paris-Nord and Valmondois via Ermont-Eaubonne (with 2-141.TC.64), and train 1748 between Persian-Beaumont and Paris-Nord via Valmondois and Ermont-Eaubonne (with 2-141.TC.54)^[2]

Preservation

One locomotive has been preserved: 4.1251 / 2-141.TC.51 (SFB 2696 of 1934). This locomotive was featured in an exhibition at the Brussels International Exposition, in 1935. It has since been preserved by AAATV of Lille, and stored at Ascq.

Models

The 4.1200s / 2-141.TCs have been reproduced in HO scale by:

RMA (French firm), brass injected model, released in 1987, 20 years after being announced
Keyser (English craftsman), as a white metal kit
Metropolitan (or Metrop) (high-end Swiss), brass model
Fulgurex (high-end Swiss), very fine brass model.
