In Control

Time to tame the electrical demons.

The back of a control panel. Starting to drill some holes for block isolation switches:

These are DPDT center-off switches which will route power to a block (for example, the "Up Main"). The theory is that with the switch in the up position, power will be routed to the track from the "UP" controller, if down, from the "DOWN" controllers, and, as the name suggests, no connections are made when the switch is in the center position.

If I wasn't so impatient I would have something clever done with that front panel but can't wait now...

The input power buses starting to be connected with copper telephone wire:

Connected to the track sections tag board:

And tacked into place on the layout:

A few more wires to attach ...

Gettin it together

Five strips of Peco Z flex track arrived in the post a few days ago. They've sat neglected in the corner of the trainroom since, while periodic rituals involving pondering were performed.

I know I should complete the wiring and build a control panel, but today I accidentally glued a section of foamboard trackbed in place, so figured I might as well go to town while the ball was rolling. This is why I scored 55% in School Certificate English.

An hour or so later I'd managed to lay the double mainline up to the 'summit' and connect up one of the passing loops at its hidden station. The apex of the third level of track is where the uphill mainline loops around to become the down main while also providing (minimal) storage so that an uphill train which has just summitted doesn't have to immediately go back downhill again.

There's still plenty of feed-wiring and track soldering to be done before a train can finally loop around continuously up and down, round and round, ad-nauseam under its own power, and I do need to see if I can eek out the storage siding trackage at the summit from the few remaining centimetres of track and few fishplates I have left, but it does seem like a milestone has been reached

Organising a Rat's Nest - wiring tagboards

As someone who has been using DCC since 1995, it seems strange to be 'stepping back in time' to a DC powered layout.

As Wassen is a whimsical distraction that I've already spent more than enough money on, adding a bunch of Z decoders and fluffing about with all of that isn't likely to happen at this stage, if at all. Especially as this seems to be a pretty simple layout with just an 'Up' track and a 'Down' track and some storage sidings.

However to make that work involves electrically isolating the track into sections and powering only the ones that you want to actually run trains on at a particular point in time.

By my count (and I did run out of fingers at one stage), there will be 9 or 10 sections on the layout: two mainline tracks, 5 sidings or isolatable sections in the yard at the bottom, and two or three up top.

As you "saw" earlier (if you'll pardon the pun), I used a Dremel cut off wheel to cut gaps in the rails. (If I'd had some plastic insulating rail joiners I might have used those, but they don't always hold the track in perfect alignment.)

Until now, I have soldered the minimum number of wires onto tracks and hung them all together in a temporary fashion to be able to run a train around for testing purposes. Obviously that's only a partial short-term solution that had to be tackled at some stage.

Today I decided to make this all a bit more kosher, wiring up all (ok, 'all but one') of the sidings:

...feeding all the wires properly through the baseboard (easy in foamboard!),

...and attaching them all to a tagboard so its a bit easier to understand and debug as required:

I've put the tagboard into a spot to the right-rear of the layout that is reasonably accessible, labeled it with a marker that you probably can't see here, and used different coloured wires where possible to make troubleshooting and adjustments easier.

Over the Top

Since it's armistice day (Nov 11), it seems appropriate to steel myself to go over the top and embark on a final big push to the summit.

Lacking the necessary bits of track right now, I'm having to make do with foamboard to see what the path across no mans land looks like. Hopefully that will be resolved shortly and the rails will be able to take their first vertical steps in some months.

Tentative steps. Looking 'north'

How small is Z anyway?

While N scale certainly has a better selection of rolling stock, when I first hit on the idea of "Wassen on a door", for obvious reasons, Z was the only scale that was considered.

Why? Because it's small. Small-enough-to-fit-a-lot-of-track-on-a-door small.

Well it's supposed to be small. But when the first of my Z purchases was unboxed, they weren't as tiny as had been expected. The locos certainly don't get lost on your workbench, the track is workable, and as we've seen recently, you can even 'model' in Z.

So to respond to a recent question/comment/request - how small is it really?

Here's a side-by-side comparison that can be readily set up with models on hand - a Z scale Swiss Re 4/4 (1:220) vs an N scale North American Dash 9 (1:160) vs a New Zealand DC in NZ120 (TT 1:120).

Crikey. After having only played with Z this year and not seeing an N scale engine out in the wild for some time, Z suddenly seemed a lot smaller than I realised. Or probably more accurately, N seemed a lot bigger.

In comparing apples with motorcycles, it's fair to point out that a real General Electric Dash 9 is a lot wider, taller and longer than the other two locomotives, but empirically, it would seem that Z is indeed smaller than the others by quite a margin.

But its not tiny. That would be T gauge.

A Desk, my Kingdom for a Desk...

The spate of recent rolling stock work can largely be attributed to the purchase of an old computer workstation and office chair from the Salvation Army charity shop. A modeling desk being an item that's been missing from my wardrobe for the past two years.

The desk had a slide-out keyboard tray which was cut down and re-installed to make a second shelf where the monitor used to go. On the right are slots for a CD library that will become more shelves for small projects in time. I suppose its fairly small, but that's entirely appropriate for the current Z scale projects. And it forces me to keep things tidy...

I also like being able to whizz around the room on my chair.

A further purchase - not yet installed - is a $4 old clamp-on bed headboard light that will be attached to the top shelf or beside the window to provide additional lumens when required.

Best $30 I've ever spent.

InterRegio 4 - on the run

While I had the cars apart for their makeover, the opportunity was taken to trip or remove the buffers that I thought might have been upsetting the cars on tight curves and causing derailments.

Seems to have done some good, as I ran these around a bit yesterday with no problems whatsoever.

Are they perfect? No of course not - neither my painting nor the Marklin canvases underneath.

...But they do capture the 'essence' of an InterRegio train; and my modeling philosophy has always been that a 'close enough' model will always look better in a bigger scene, which allows me to steam through these things relatively quickly rather than seeking absolute perfection - or never finishing anything before losing interest.

One day I'll make some decals. I promise. In the interim, as far as I'm concerned, without my glasses on and squinting from the other side of the room: This train looks the shiznit.
