Computer control: parts and tools
The generic tools and parts our guides call for in computer control, each with the guides that use it. The links search Amazon.co.uk so you can compare what’s available — we don’t recommend particular products. For DCC-specific items such as decoders, check the guide and the maker’s compatibility list first.
