Joined: 04/05/2015(UTC) Posts: 777 Location: England, London		Moving quickly on from my "everything stops for tea issue" I have been evolving my layout a little today We now have Transformer 6001, 6021 2 keyboards, 6043 memory which run simply 5 k83 decoders for turnouts all looped with a red/brown bus that goes nowhere near the track. From the transformer we have the yellow and brown wire set looping round a modest lighting circuit. WE have an MS2 linked to an M84 and four hobby signals and linked to the track. So we switch it all on and am really happy everything works except my good old level crossing which has a yellow wire and used to take its brown from the track. My brain says I must not use the brown from the MS2 as a common brown but how do I get the crossing to work?

Make a common brown - or add "Out of order" signs to the level crossing. Electricity works best with closed circuits. The electrons that use the yellow wire to get to the level crossing also need a way back.

[at least thats how I think it works]

The "yellow wire" indicates that external power is used (which makes this thing also suitable for analogue operation) - and then a brown wire is also needed to close the circuit. The term "good old level crossing" lets me assume it is a level crossing from the analogue days.

In the meantime I will leave it with one barrier up and one barrier down on the assumption we are half expecting a train.
