Additional arms for use with the PL-25 N Gauge electro magnetic Decoupler (Pack of 32). A useful remote operating feature for use with the ELC couplings, which are easily modifed by adding the unobtrusive Coupling Lift Arm. The uncoupler attracts the steel lift arm down, pivoting the coupling upwards by creating a temporary magnetic field under the coupling. Uncoupling only takes place when required, at other times trains run through unaffected. Note: this device is not suitable for couplings fitted with springs.
