DCC prog track common pole?

[Nodrog1826]

Just wondering if the above is feasable/advisable?

Running three wires one to the normal track, one to the prog track and a common 3rd wire to both.

Is it a no no, can it be done, and would it matter which pole was the common?

Now befor you ask why, its just that i have a isolated prog tack/siding and a DPDT switch which can make it work either way,
and am considering an additional feed to all my track from the house rather than lugging the controller to the shed.

Have plenty of wire to do either two pairs or one and a half.

Personally I would go for separate feeds and the DPDT switch option.....That's what I have here

Drive em on, flick the switch, program, Flick the switch and drive em Off again

The programming track normally has inbuilt current limitation to avoid major meltdown if a decoder being tested/programmed is installed incorrectly. It's probably not powered through the same amplifier/booster as the main output.

My advice would be stick with the DPDT switch.

I would use a totally separate piece of track. Sooner or later a loco will bridge the join (DPDT switch or not) and you will re program everything on the main track.

... or short across and blow your programming track feed.

Must admit I do all my programming on a rolling road with a SPROG, on my workbench in my hobby room, well away from the main layout and with a PC to hand for reference to manuals and forums etc. (as well as for driving the SPROG).

Set yourself up 1mtr of track and program on that.
