Basic Model Loco Installation [with RBT and HRB]

Here’s an outline of a basic controller installation for a model loco. This version includes our RBT hand control box and HRB horn relay board.

A wiring diagram of a basic model locomotive installation.

We’ve omitted the detail of the wiring for the HRB as there are a number of possible variations, these are covered fully elsewhere.

We’ve also only shown two motors, but it is possible to connect many motors in parallel.

This drawing also shows a separate battery isolator and fuse, for lower current use [<60A] these can be combined into a single breaker.
