Hi Eric. If you put an analogue powerbase into a circuit it will only deliver power when you pull the throttle on a controller plugged into that powerbase. So any second or third powerbases around the track will not deliver any extra power to the track. If you were to do that on a digital layout, it would be the same - no extra power. And you really wouldn't want to mix the AC power from the digital powerbase with the DC power from the analogue powerbase. It might be a very expensive disaster.
The way to avoid power drops as you move away from the powerbase is to:
- keep the track clean
- keep the track connections in good order
- install power taps or 'jumpers'
That's the same for analogue or digital tracks and there is more here: www.scalextric.com/uk-en/support/track-maintenance
At my local Scalextric digital club, we build temporary tracks every month for an evening or day of racing. The circuits are 100 to 150-foot long and built in just over an hour. The track is given a good clean once a year and all the track tabs tightened. During construction, if the connection between two track pieces feels particularly loose, we will tighten the tabs.
Each race track is built with two or three power taps running from a track piece next to the powerbase to 1/4, 1/2 and 3/4 of the way round the circuit (or 1/3 and 2/3 for shorter tracks, or one 1/2 way round for tracks of 30-50 feet). A power tap is simply a length of wire that runs from the rail of one track piece to exactly the same rail on another track piece. Scalextric produced their own C8248 Track Power Bosster Cables, but these are hard to get hold of. Jadlam Racing Models have their own version: www.jadlamracingmodels.com/scalextric-c8248-sport-track-power-booster-cable-2x/
The first cars to be run after the track is built have one drop of INOX MX3 put on each braid and the cars are run round the track, over the lane changers and through the pit lanes. INOX MX3 seems to work perfectly to clean and condition digital track rails, limiting electrical arcing and keeping the digital signals as good as they possibly can be. I would say it is a must-have for all digital racers - if used in small amounts. Pendle Slot Racing sell INOX MX3 in the UK and have two products. I would recommend decanting the pump spray into small dropper bottles. www.pendleslotracing.co.uk/brand/inox
After the racing, the disassembled track pieces are stored in covered, dust-proof cardboard boxes without being cleaned - the INOX stays on the rails to protect them between races. The next month we build again... And we experience very few power issues during the year.
I hope that helps.
