Märklin small digital controller 67025 + power supply 66201 (18 VA), like new, see picture. The items come from starter sets and therefore have no original packaging. Unlike current joystick-like models, this device features a real rotary controller with direction switch.

Using this, as with the traditional Delta system, up to 4 locomotives can be controlled independently on one track, with enough power to run 2 locomotives simultaneously. A slide switch selects the Delta locomotive addresses 24, 60, 72, 78. Additionally, there is a light button to switch the headlights on Delta or digital locomotives.

Caution: If your locomotive does not have a digital decoder or uses an address other than the 4 listed above, and you cannot reprogram it with another suitable device (Mobile Station, Central Station, or 6021), this controller cannot be used.
