Introduce your locomotives to the digital age with these basic one-amp decoders. E-Z Command decoders are compatible with NMRA compliant DCC systems. Features include: service mode decoder lock for main line programming, two- or four-digit addresses, advanced consisting and 28/128 speed steps. Decoders can control speed, direction and lighting functions and are offered in two versions with wire harnesses (for hard-wiring) or with eight-pin plug (for DCC-ready, NMRA socket-equipped locomotives).
