N4L Accessory Decoder For N-scale, Kato #4 turnout (Left)

N4L and N4R accessory decoders are uniquely made to fit inside specific Kato Unitrack® turnouts in order to minimize the work required to install them.  PDL spends extra time engineering these decoders to conform to available space, electrical connections and mechanical attach points for ease of installation.  In this way, they perform a "disappearing act" whereby they carry out their function to listen for and respond to DCC commands on the rails while their presence is unknown.  N4L and N4R make Kato N scale #4 turnouts ready for your "Digital Railroad" with minimal installation effort and maximum convenience of no external boards or wires to "complicate your layout presentation," whether temporary or permanent.
