NJ International, Inc.
Model Railroad accessories in HO-N-S-0 scales
Our products are fully compatible with all signals, scales and control systems, DC or DCC, and operate independently of these systems
Our systems include detection and provide prototypical
operation independent of track power.
No soldering is necessary and installation does not
disrupt existing layouts.
