More track laying

Finally, finally, I got some more loft time today! I used it to lay some more track in the storage sidings. Because I am gluing the track to the trackbed, I need to leave it alone while the glue dries, and so I had time to install the track bus wiring. Suddenly the bundles of wires start to look impressive.

Most of the track bus connections are now soldered to the track and run back to connector block into which the DCC power is fed. So far, so easy.

The newly laid track lengths themselves are not yet broken at the section breaks. I will do that later once the track is all laid, secured and wired. As mentioned in a previous post, the trackbed level at the section breaks has to be millimetre perfect; by laying the track across the break I hope to establish the alignment and then cut the track with minimal impact on the rail surface.

In the course of the past few weeks I have also, in odd moments, managed to get the three point motors connected up and working. I really do have an increasing need for the control panel.

The next step is to extend the storage sidings the other way (B4 and B5). All looking good so far.

That satisfying click

Today I got power into the point motors for the first time. It was very satisfying to hear the "click" from one of my already-installed motors when I fired it up, telling me that the circuit works. Automatic point operation is going to be crucial, especially on the lower level tracks that will mostly be covered over.















I'm using various Peco bits and pieces, like the capacitor discharge unit and the probe & studs, recently acquired. For the moment it's all mounted on a bit of hardboard so I can wire up new motors to test them. Eventually I'll put it all onto a proper control panel, once I've worked out where, in the increasingly cramped work space around the layout, I'm going to put it.

What happened to the branch line?

Having re-read yesterday's post about track laying, I realised that there is a gap in the story. My previous post talked about finishing the branch line and then starting the track laying. So what happened to the branch line?

Basically, nothing. The more I have thought about the branch line, the less convinced I have become that its course along the front of the layout is the right one. Scenically it gets in the way of the mainline, especially the bridge on F2; operationally it doesn't add a great deal of interest. I really want the branch line to come in from a different direction to give more visual interest and more scenic scope. A possibility is to build a branch-line trackbed on top of the spur carrying the new loop from F1. This would take the branch line along the side of the loft and make a separate little vignette that is more or less independent of the main layout. Branch line trains would run through this, past a scenic break of some sort, and continue onto the main layout past the F1 sidings and into the mainline station.

Well, it's an idea, and I have to think about it some more before committing myself. In any case, the branch line is now also, like the new loop, temporarily on hold. I have plenty else to do: laying track and turning this pile of wood into a working railway!

Track laying #1

The past couple of weeks have seen slow progress as I get to grips with the skills needed for track laying. I had naively thought it would be an easy task. I have started on the storage sidings with the intention of doing all the under-cover stuff first before putting the lid on.

Because the layout has so many section breaks it's important to keep everything as level as possible. My first attempt has not been altogether successful:















It isn't too bad, in the sense that it doesn't derail trains (although in this shot one might think it would), but (in the language of another universe) it doesn't pass my own QC check for smooth running. So I'll be working to improve my technique over the next few weeks.

In the course of the track laying I am also installing the PL-10 point motors under the trackbed. All the points in the shot below have holes cut, and motors attached!















I have managed to get power into the track and run a train up and down the short section that's been fixed so far. It's all a bit cobbled-together (as the photo below shows) but so far, it works well enough.















The relict Hornby R900 (still in good condition though!) was donated by my brother-in-law and serves a useful function as a 15V AC power source to drive the point motors. The Select DCC controller has no such output. When I build the control panel I may install a custom power source but this will do for now.

More progress on the new loop

Since the last post I have been busy fixing, aligning and generally securing the trackbed for the new loop and the re-routed inner loop. It doesn't look much different, actually, but is a lot steadier than it was, and ready to accept track when needed.

I have also taken up the old branch line trackbed (sob!) and installed a new one (or most of it) along the front of the layout. This, when finished, will connect with the outer loop near the sidings on F1. The new branch line isn't the most exciting of routes but should make for a more manageable gradient.






























Having got this far with the new loop, basically having both ends of it plumbed in and ready, I've decided not to do any more work on it for the time being. It will be easy to return to it in due course, without any disruption to the main layout. So once the new branch line is connected up I will return to the first fix and the track-laying. I really want to run some trains now!

Finally, a gratuitous shot of my birthday present from Karen. A very welcome addition to my motive power fleet!

Track plan revisited

While watching the Last Night of the Proms on Saturday I came up with a new version of the track plan, this time in Visio. I wanted something that was less literal and more schematic, something that I could eventually use as the basis for the layout control panel (with point motor studs, indicator LEDs, that sort of thing). Here is the result:


















Black tracks are "visible" parts of the layout. Blue tracks are the sub-surface lines. Green is the new "relief" loop. The track labels should largely speak for themselves.

I am pleased with this as a first attempt. It will, of course, need some revision. But when I am finally happy with it I should be able to have it screen-printed onto something that can form the front of the control panel.

Progress on the new loop

As hoped, I've at last been able to do some work on the new loop. The alignment is more or less (barring the usual tweaks) in place at both ends of the loop. Here is the loop junction on F5, with track added for illustration.





























And here's the new spur on F1 looking towards the back of this section (the section is currently resting on others along the back). Not a good photo; sorry.















On F5 I now need to realign the outer trackbed (F5o) as there's no longer enough clearance where the new loop spur crosses. This means starting and, of course, finishing the outer gradient further round the loop.

The other casualty of the F5 realignment is my neat little branch line feeder than snakes to and fro among the trackbed supports. The newly moved gradients now don't allow clearance for this any more, so I will reluctantly have to move it. The easiest solution will be to take a spur off the F5o mainline feeder, just after it emerges from under the new loop spur. This might also soften the gradient on the branch line, so it's no bad thing (although a less interesting alignment).
