... and only if I was to change to DCC what should I buy?
I note the folks hereabouts appear to rate Lentz quite highly. ZTC is expensive and IIUC not fully compliant with the standards such as they are. But what about the recent Guagemaster offering - I do try to buy British as much as possible.
Also what would I need?
Initially I would be looking to "DCC" a 009 layout, total track is around 60' (final bits still need to be laid so it's not an exact figure) and of that the longest run on the "mainline" is around 36' from buffer stops at one end and around a reversing loop at the other. The remaining trackwork consists of spurs from the "mainline" (quarry workings/interchanges/factory yards/small shed/sidings etc).
I can't see that I'd want to run more than two or three engines at once (single train double or possibly triple headed on very rare occassions) out of a total proposed stud of 6 to 8 engines.
If the experiment is sucessful I'd then (at a later stage) want to incorporate the 00 part of my layout (currently DC) - around 200' of track, the longest runs being two 'ovals' each of around 45', lots of sidings and a reasonably large engine shed. Anticipated that around 20 -30 engines could be stabled or run on the layout at any one time.
