The NORD 220 JEP Made 12 1934 is a shortened model of the larger Pacific 231. it is called "Flechette" in France by collectors. In the original sets the tracks where near 031-032 and it will ever run on 042 lionel tracks. two different motors, easy to identify, there is a silver plate on each loco with the type of motor and needed voltage.
1 Tous courants S52. (All voltage S52) That mean it runs from 20 volts to high voltage. 50-70 volts. It will run with a ZW Lionel without any problem but will perform better of course with a rehostat.
2 Bass volt S59. That means it runs only with 20 Volts. it will accept a little more 22-24 but NO more. There is two types of reversing system. One with a lever under the cab, the other is a more sophisticated system included in the tender with three wires between the loco and the tender.
Those two models use AC curent but run equally well with DC.
Picures of the two models,
20 volts manual reverse, with brass lever under the cab,
And 20 volts with automatic reversing in the tender,
Of course they look better running on larger radius tracks,
