2016_05_17 (Stepping Back) and working on track circuits and signalling.

2016_05_17  Well the damage to the back scenes has gone no further. Sheet one is rippled and needs replacement, however sheet two is quite acceptable, making me think that a brand new unused sheet two might go on perfectly with what we have learned. But stepping back for a little while.

So what has happened whilst this wall scene drama has been escalating. Not a lot

Wiring:-    As the wiring has been changed so many times, I am bound to find problems. This happened a few weeks back when I found the branch line was shorting out. Not enough to set of circuit breakers. But a certain amount of warmth was found in some heavy wires.
Disconnecting them stopping the short and then carefully adding the droppers back into the circuit locatied at least three insulation problems and I have not reached the end yet.

I found that when the wiring was removed some track sections were still live. Bullioh was getting an unwanted + feed from the north and a - feed from the other end.
Then I found some droppers had been connected to locally protected circuits and others had somehow been joined to the DCC bus lines. This of course bypassed the local circuit breakers.

So I gradually removed duplicated feeds and got everything to go to where it was designed to go. Just a few droppers to solder in place and that maintenance work will be finished
Signals and Detection
I also started locating some San Mateo Signals.  They are pretty good. The only problem I have found is that these signals use a common negative and the nice Australian made detectors I found on EBay are DCC compliant. This QLD supplier is going to fool around with his circuit and see if he can modify it to be common negative. What a champion! I am pretty sure some others out there might like to buy a San Mateo detector from a local business that shows a lot of care for his potential customer

The new baby....  E Class
I also noticed an E Tank loco was offered for sale on Face Book. Of course I asked to get second  offer if the first guy did not go on with it. I was offered the engine on the basis that the seller wanted funds in a few days, and that is how I bought this....

And as I don't think this is a loco that will not make it in plastic in my time, I am happy with the opportunity :)  Looks pretty nice I reckon?
Cheers
