The 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. This is handy to have as the uncoupler is totally hidden from view.

When the uncoupler is off it has no effect on the couplers on your equipment. That means you wont have any unwanted uncoupling. This is really handy in large yards and on the mainline, especially near runaround tracks or industrial spurs
