QUOTE Another question. Does a loco require more than one address reserved if sound and lights are fitted?
No but it has the advantage of having the decoder already fitted.
QUOTE Now given that I class myself as an average proprietory home hobbyist playing with transient set track layouts my largest ever home layout had 19 points, 8 signals and had 6 trains on the track at any one time. This was an exception and 10 points is more the norm.
How many addresses would I need to have this all under DCC control?
You would only need two as a bare minimum but then you would have a basic obsolete system with no room for expansion.
QUOTE OK I may have more than 10 locomotives but I would never go out and buy a chip for them all. I may have a pool of chips which I can move around depending on which locos I want to have a DCC play with.
You've obviously never fitted a decoder to a Hornby steam loco, as mentioned previously see Dougs efforts with the A3 and Brittania. You're only going to put yourself through this once. As I mentioned elsewhere to fit a decoder to a Hornby steam loco you're talking several hours as opposed to European locos where it can actually be seconds. In reality no-one is ever going to do this.
All these questions are really missing the point though. Yes you will get by with a two digit address system but it is not an international standard. It's a bit like buying a Betamax video it will work but no one else is using it. At the end of the day to a non DCC user a two digit addressing system may seem ok but once you learn about what you're doing and your limitations you probably will regret it.
