So today has mainly been wiring - not a lot extra is running, but the infrastructure is now in place for the running railway to expand pretty much as soon as it is laid. With one caveat to which I'll come later...
So as of this morning, this shows the amount of track currently laid, and the switch for the 1 functional point temporarily poked round the turntable well. It also shows that I forgot to integrate a cup holder, but we live and learn. The location it is sat in will probably be scenery free for some time to come!
On the underside, all the servo point motors have now been installed, alongside chocolate blocks to feed on their connections. Track feeds have made it on to board 2, and the 2 boards are currently linked by a flying lead DIN plug & socket. I think this is a temporary measure...
All the track feeds go into earth blocks, 1 block for the 'front' rail and one for the 'rear'. Common crossing feeds go from the servo built in switch to the common crossing, although 2 of these need to cross the board joint (and indeed now do!).
As well as the track feed the 'main' board (right hand, with turntable) has another set of earth blocks, and these are for the 16VAC accessories - currently just the servos.
I have made a control panel - nothing fancy, just a slab of hardboard. I toyed with the idea of something more extravagant, but all the points in the yard were manually controlled anyway, so I'll save playing with a more complex arrangement for when I model somewhere that the prototype had one! Currently I have (very) roughly drawn on the control panel, but will paint the board white and overlay the track diagram more neatly later. The switches are fed with 16VAC, and steering diodes half wave rectify the feed to the servo so that a 1 wire feed (and a common return) switch them across either way as required.
So there are currently 3 sections that have working track feeds now (4 including the temporary flexitrack length!). The feed from the turntable well and the first point are fully functional. The section between the 2nd and third points (with a 6 wheel fish van sat on it in the photo below) functions, and the headshunt in the far corner works too. This in itself doesnt get me very far, but all I need to do is implement my point tie bar on point 2, and then add the switch blades and tie bar on point 3, and thenthe full length will run. With the motors already in place, and the control panel, point 2 will work straight away - point 3 needs the switch feed linking between the boards though.
So I'm happy with the infrastructure. The control panel will be mounted on the underside of the lid, where the track plan is currently blutacked. What I havent finalised is the board-board connection. a loose link wire connected by DINs is ok, but will mean a trailing wire if and when I move the boards around. I would prefer 2 panel mounts and a cable between, but if I did that at the rear it would mean they couldnt go back against the wall, and doing it at the front would look a bit untidy when plugged together. I dont think there will be a perfect solution, so will probably just stick with the lead option and drill a hole somewhere so the plug can locate in the frame of its own board when the 2 boards are being individually transported.
Anyway, onwards with tie bar construction (as photographed/documented here when I constructed the first one, whose operation I am more than happy with.
