Tornado 16

Certainly works on my mid 2012 MacBook Air which is still going strong.

Yep, that's the current plan. Thanks for all the help.

RAF. Understood. It's a relatively simple 25 ft end to end 'U shape'. I'll be doing conventional bus wire with droppers to each track piece. If the odd siding works satisfactorily with point clips I might just use them there to save a bit of soldering but they'll be in the minority.

I hadn't realised there was a difference in power tracks, or that it's actually DC powered, which makes sense now that you mention it. I bought the digital one as that was on the Hornby HM7000 page. At the time I hadn't considered the need for bus wires - the old Zero 1 worked perfectly with just track turnout clips on all the points! Sadly, re-using 45 year old Peco streamline track and insulfrog pointwork which, whilst still in very good condition, requires a bit more help in the connectivity department to run HM7000 decoders. I know I should use electrofrog points, but I have over 45 old insulfrog ones and really can't be doing with converting them all.

Thanks for that. Simple When you think about it! So in hindsight the power track was rather a waste of time, other than perhaps to save soldering one dropper. Out of curiosity, is there any benefit to loading profiles on a separate track? I thought that one of the advantages of HM7000 was in doing away with a programming track.

I am building a new layout as a retirement project and need some advice with connecting a bus wire to a HM7000 system. My previous layout was powered by a Hornby Zero 1 (last used in 1990) so I have no other controller. Power is provided by a P9300 power supply via an R7324 HM7020 15V Power Supply Adapter into a R8241 Digital Power Track. How and where do I connect the bus wire(s)? I'm sure this must have been addressed before but I couldn't find an answer via the search facility.
