Building from scratch a model train controller part 2

In part 2 we build the circuit and test it, initially there was a mistake but it was soon fixed and there were some amazing results. Step by step assembling the PCB, checking and testing. Circuit from the book: Model Railways Electronics by Roger Amos Please note, contrary to the original circuit I have since discovered that a small filter capacitor needs to be fitted on the input supply. A 33uF at 35 volt electrolytic has proved to be just the right balance between maintaining control and allowing Portascap type coreless motors to work without issue. Please include this within the power supply output circuit.
