Comments

Very nice coaches. The junction body-roof is visible, but discreet and regular. One detail comes to spoil the good impression, it is the too great width and the little discretion of the (many) steps. Indeed, their width reduced to 1:1 is more than 3.2 m, for a UIC gauge of 3.15 m! It should be noted that the step uprights pass in front of the steam hose on the model, while they pass behind in reality, at least on the coach photographed. This widening is probably explained by the need for inscription in curves.

The fact that the central doors were locked out for service at the end of their career and therefore their steps and handrails removed is respected (and there is no corresponding hole!).

The engraving of axle boxes is remarkable: there is not only the Athermos acronym, but the manufacturer’s name below!

For once, LS Models has not been stingy in spare parts. We find not only detail parts: brake couplings, heating hoses, etc., but also and especially replacement parts: folded bellows, steps (that’s good!), aerators, handrails, buffers. Bravo!

This time, the Fleischmann Profi couplings can be easily mounted in the NEM box, forcing a little. On the other hand, I noticed derailments in large radius curve due to too tight buffers, whereas the passage in the same curve is normally with a space of about 0.5 mm between buffers. I suspect a random blocking of some drawbars in their guide.

Modifications

  • Solving the problem of drawbars jamming in curves.
  • Insulated half-axles (current pickup by brass bearings). Lighting controlled by latching reed switch.

History

Coaches made in 245 units from 1928 to 1936 for the Compagnie du Nord. UIC numbers: 50 87 21-47 360 to 444 (85 coaches), 50 87 21-60 445 to 471 (25 coaches in the series), 50 87 21-17 251 to 329 (79 coaches) and 50 87 21-47 330 to 359 (30 coaches), these numbers depending on the type of heating and the speed limit (120 or 140 km/h). Withdrawn for the last in 1980. Weight about 48 t.

These coaches were originally of the 3rd class C11 type, No. C11y 15005 to 15249.

With a central corridor, they were equipped with 5 doors per side (one every two “compartments”) and two central WC. At the end of the career, the central door was locked out, the corresponding step and handrail removed.

I wonder about the validity of the concept of these coaches, multiple doors meant to accelerate the access of travellers, but expensive and complicated (curve, lock). Moreover, was not the time gained when the passengers were boarding up lost by the fact that an agent had to go along the entire train to close the doors? Finally, the typical and pronounced shape of the bodies, necessary to give way to the steps, reduced the space at the feet, making these coaches quite — very? — uncomfortable.
