Morley and Gaugemaster model railway controllers compared. How a controller works.

An in depth look at analogue DC controllers focusing on the Gaugemaster model D and the Morley Vector Zero 2. Also how these model train controllers work.

This is a long video with many technical discussions hopeful put in simple terms.
