320001 Railcrew On-Off Remote Uncoupler Brand_Heljan for instanceThe RailCrew ON OFF Remote Uncoupler sits under the roadbed to reliably uncouple locomotives, passenger or freight cars, no matter what brand of standard magnetic knuckle couplers you use. At just 1 3 4 wide (44mm) and 7 8 deep (22mm) its not much larger than a permanent magnet and can be easily controlled by DCC accessory decoders. It also features an LED between the rails that marks the uncoupling zone which only operates when in the ON position.
