Comments

No dismantling instructions, only a list of spare parts and tips for preparing etched plates are present. These plates, as well as the handrails of faces and cabs, are to be assembled.

The wheels are not burnished, but they have a plastic hub cap showing the transmission details.

The six axles are driving. So it’s not an A1AA1A, but a CC! The problem is that, having a smaller diameter, the “carrying” wheels will have a lower peripheral speed than the driving wheels and will slip! Weird solution… already used by Fleischmann forty years ago!

The markings are pad printed. The name of the depot is not very clear. Photo-etched nickel silver plates are supplied: it’s up to the user to strip them to reveal the marking, which will be yellowish and not aluminium-coloured!

Lifting the body is easy: just spread the sides. We discover a fairly clear double-sided printed circuit. The connection to the lamps is done by flexible circuits. The lamps are still incandescent! The white and red lights are linked. Their separation doesn’t appear obvious at first sight.

This machine doesn’t have an extraordinary pulling force: its cousin 67580 from Jouef pulls it like playing!

See gamos81.altervista.org for the list of references of issued 68000 models.

Modifications

  • Mounting details: engraved plates stuck with double-sided adhesive, handrails glued with CA.
  • Lenz Standard+ V2 decoder.
  • Front elongation device removed (no more NEM box visible).
  • Separation of red lights (see Loco-Revue forum). Masking of third front light generally unused.

History

Locomotives built in 80 units from 1963 to 1968 by Compagnie des Ateliers et Forges de la Loire (C.A.F.L.), Compagnie de Construction électro-mécanique (C.E.M.) and Fives-Lille-Cail (F.L.C.). UIC Power 1660 kW (Sulzer diesel engine type 12 LVA 24, 12 cylinders, direct injection, 1980 kW. Maximum speed: 120 km/h (130 km/h in Caen). Weight in running order 106 t.

The 68000 are slightly more powerful than the BB 67000 (UIC 1260 kW), with whom they can be coupled in multiple unit. The main difference is that they embed a boiler for steam heating of trains. A system of interchangeable holds made it possible to adjust the load on the carrying axles. It has been used very little, and the load is set at 18 t per driving axle, which allows these machines to run on almost all tracks.

The A1AA1A 68005 was built as 68501.

A1AA1A 68053 is put into service in June 1966 in Limoges. Successive depots: Tours St Pierre (9-75), Sotteville (date unknown). It is cancelled in April 2004.

There was no 68000 in the Nord in the 1960s and 70s. Those who came to the area were probably based in Caen, as 68046 (in original livery) and 68047 (in simplified livery), but both with original cabs, visible in Boulogne sur mer in 1973 in this photo of Michel Costes (railpictures.net).68046 et 68047 à Boulogne sur mer
