Resp. 174, 169, 172g; 139 to 142 g after removing the ballast (NEM: 121 to 158g)

As on previous MU ACME, the roof is moulded with the body. The scale is almost perfectly respected. The three cars have specific details (length of the handrails, heating cable housing, various grids, etc.)

The height is consistent. On the other hand, the mass is a little too strong.

Steps and CIWL badges are in photoetched metal. The compartments are in night position, the ladders are in place. Some blinds (blue) are more or less lowered. The little FIAT car handles are to be mounted, and it’s a little tricky… The buffers are on spring, and, of course, they get crooked…

On the FIAT car, the Y24L bogie wheelbase is marked 2.3 m, whereas it is actually 2.5 m (however, this dimension is well respected on the model).

The bogies are equipped with current pickup strips rubbing on the axles, which makes the rolling quality rather random; the Y24L bogies are equipped with brass bearings, while the Minden are not. The wheels have a correct diameter of 11.0 mm, but their spacing is a little low compared to the NEM 310 standard (14.3 instead of 14.5 ±0.1). Flange height: 0.8 mm. Axle length: 24.3 mm.

See:

Modifications

  • NEM boxes shortened by 1.5 mm to suppress the gap between the cars.
  • Ballast (30 g) deleted.

MU cars concerned, not air-conditioned:

  • CIWL No. 4701 to 4740: built in 1964 by Brissonneau & Lotz; they are mounted on L bogies, extrapolated from Y24 SNCF bogies, but with a wheelbase increased from 2.3 to 2.5 m, except for the last four mounted on M3 bogies;
  • CIWL No. 4741 to 4775: built in 1964-1965 by FIAT Materiale Ferroviario, mounted on L bogies;
  • CIWL No. 4776 to 4790: built in 1964 by Waggon- und Maschinenbau GmbH Donauwörth (WMD), mounted on Minden-Deutz type M4 bogies.
