This is the first series of USI cars designed by LS Models in collaboration with Heris. Moulded stunted handles. Bogies whose pivot is off-axis and which don’t have a rotation stop turn easily perpendicular. The electric heating cables have a funny look. The compartment interior windows sides are not vertical.

Body too low, wheelbase too short of 7 mm! I don’t understand this: the wheelbase has certainly been shortened to facilitate running in curves. But wouldn’t it have been favoured as well by respecting a more correct chassis height?

The reference 14016 has a 1st class yellow strip voluntarily shifted upwards (variant).



  • Body raised by 0.7 mm by interposing polystyrene spacers. Therefore, it appears a space between the body bottom and the bogie suspension consoles. The displacement of the latter from the bogie to the body (actual position) is under study, the problem is to ensure sufficient strength while allowing the movement of the bogie.
  • Pivot distance corrected by changing the position of the bogie pivot axes and cutting part of their side beams at the step boards. The picture of two cars together show them after rectification of the centre distance.

Cars called USI (Unifiées Service Intérieur — Unified for Interior Service), on Y28 D bogies, built from 1966 to 1970 by the Ateliers du Nord de la France (ANF).

The car has in its middle four classic compartments six seats each, framed at the ends by rooms with central corridor. In these, the seats have three-position reclining backrest. This explains the pitch of the windows, wider in the middle than at the ends. The B10t 2nd class car body shows the same configuration, although it is not necessary in this case.
