Perfect for Tight Spaces
Modern locomotives don’t leave much room for excess wiring. TCS 30 AWG wire is thin enough to route cleanly without pinching or binding, yet durable enough to handle repeated shell removals and service work. It’s especially useful for compact switchers, steam tenders, and installations where clearance is limited.
Why Choose TCS Wire?
Unlike generic electronics hookup wire, Train Control Systems wire is designed with model railroad installs in mind. The insulation feel, flexibility, and consistency are tuned for long-term reliability inside locomotives that see vibration, heat, and frequent handling. When you’re installing a quality decoder, your wiring should match that standard.
