| 206 | Model for DC, without sounds |
|---|---|
| 206/B | Model for AC, bogies, couplers and sound effect generators according to US standards, change of travel direction through stopping (3AC-0) |
| 206/T | Model for AC, high flange on wheels, couplers compatible with models of the "Tin Plate" era, change of travel direction through 20V impulse (3AC-1) (Märklin transformer) |
| 206/S | Model for DC with the electronic sounds generator |
| 206/3 | Model for DC without sounds, but adapted for three rail track (high flange and central current collector) |
| 206/3S | Same as 206/3, but with the electronic sounds generator |
| 206/3AC-0 | Same as 206/3, but for AC, without sounds, with direction change reacting on a STOP |
| 206/3AC-1 | Same as 206/3, but for AC, without sounds, with direction change reacting on a 20 V impulse |
| 206/3SAC-0 | Same as 206/3AC-0, but with the AC electronic sounds generator |
