There might be a signal box Roddy but I'm thinking not much more than a plain backscene and grass embankment - much like Balbeggie. I want focus to be on the trains and while there'll be trains passing there will also be trains arriving and departing the sidings alongside the loop. There will be little doubt that this is coal country!
It's still a layout without a name but at least we now have some movement. I've threaded bus wires along the entire length of the layout except for the removable end section and by soldering half a dozen droppers in place I'm now able to run around the full length of the outer main line. After cleaning the class 66 loco wheels and collecting my trusty 26024 from the garden shed in order to haul the track cleaner round I was able to record 66022 hauling a rake of 36 MGR's along what will become the scenic section.
It suddenly seems a less daunting task than it did earlier and the fact that it's been possible to achieve decent running with very little effort makes me keen to keep going forward.
I use the blue and brown cores from 2.5mm domestic electrical cable for bus wires on both outdoor and indoor layouts and as far as I'm aware I've never experienced voltage drop. There does tend to be a lot of discussions regarding voltage drop but I can't really say it's something that's ever concerned me and if I've had it previously then I must have been completely unaware of the fact! I don't think it's as big a problem as people seem to assume.
On my previous garden railway I didn't use a bus wire at all and simply soldered a short wire to the rails across each rail joiner, as many people do, and ran trains without any problems whatsoever.
I wouldn't think there would be any need at all for each loop to have it's own bus wire. If you choose to go down this route the one bus wire should be sufficient for several loops.
Holy thread resurrection, Batman.
For a 'large' layout - i.e. around a garden of 60 metres long - would anyone recommend droppering to a length of heavy duty electrical flex, to try to minimise voltage drop? I'm planning on doing ths - basically every track loop gets its own three core underneath. At the moment, the longest planned run between two 'control sheds' is 30m or so.
