Really good tips here guys thank you so much

I think I was concerned about a drop in the current as it went further from the source and with the number of droppers I would be attaching.

Dear Chrissaf This is really helpful and exactly what I need to know. Now I can work on this better. Many thanks for taking time to explain.

I am thinking of building a fairly big layout over the next year with areas that could be easily split into 3 or 4 sections that might have say 20 points in each section. Would it be best to have three / four bus wires to each section from one control module and if so how do you manage the train moving across to each section and is there a risk of short circuit?

I am new to this but wondered how modellers manage to de couple engines from coaches at terminus stations and how do you stop a train in a covered station where you cant see the front end because its uder cover of the station roof?
