Dartmoor, Down Under

I found this interesting and very nice layout of Princetown, situated in Australia where the general standard of railway modelling seems to be very high.

So I thought I’d post a link and give myself something to aspire to.

Build a Road-over bridge

I had hoped to find a laser-cut bridge kit somewhere on the interwebs, but nothing looked quite right.

My DAS chip method is tedious, but it looks so good. I think I’m committed to it now, if only to maintain a “look” across the layout.

I looked around Google images for a bridge to base Boltorr’s on, but didn’t find an example which fitted Dumnonia’s needs better than the one illustrated on the cover of “Impermanent Ways v6“. So I’m not certain the rights’ issues involved here, but buy the book! The whole series is a huge resource if you model in this area.

The real issue when building a model bridge which never actually existed, is getting the arch right.

The photo of the bridge on the cover is on the oblique, so I used an image editor to square the perspective and match an ellipse to the arch.

I then reduced the image to black & white to produce a template. I’ll jiggle with the width of the bridge and the chord of the road deck to fit my location.

In Boltorr’s case, this means spanning the branchline, a siding and possibly an extension of the platform under the bridge. I will also have to adjust to accommodate the road level above.

At this point, I’m not considering a hi-tech solution. It’ll be a combination of printer settings and a pair of scissors.

For construction I’m going back to 2mm MDF with appliqué stonework courtesy of DAS. This provides the most stable foundation.

Boltorr Dam and the rail bridge abutments were built using foam-board which tends to take a form of its own if it possibly can. This is not necessarily a bad thing, but for engineering elements it’s a problem. MDF resists the urge to distort far better.

Moorscaping…

Just a progress report. Building your own world, even a tiny corner of it, is hard work!

It has always been a part of my brief to get as much elevation as I reasonably could and I have to say it’s working out.

Actually rather too well in that the Boltor Brook seems to have carved itself a fairly impressive gorge through the millennia so I’m having to rewrite the narrative a little. But there are gorges elsewhere on Dartmoor, so it’s not improbable. Besides it’s my universe, so…

Structural work on the dam’s basin is done and sealed for landscaping and water effects.

The iron rail bridge has been set in ready for track laying with a little final adjustment to the abutments to fix a couple of issues. It’s safely stored away while landscape effects go in.

Some plaster slip has escaped onto the masonry but this is easily brushed off for the most part and will be weathered, vegetised, etc when it all comes together, at some vague point in the future, or maybe in the past. You know what private universes are like.

Now the bulk of the terrain from the basin to the Boltorr road overbridge has to be set in.

I’ve plotted the track of the access road to the dam with a turning point and overlook for intrepid walkers. The path progresses northish towards the road with a shortcut for sightseers from the platform.

I really have to start detailed thinking about the road overbridge and construction. This element acts as a scenic break too and has to incorporate a bus stop and normal access to the platform. This was built way before any modern disabilities’ acts, so it’s likely to be just steps down.

More Nostalgia…

A slideshow of images on the Marsh Mills- Launceston branch in 1962.

The Boltorr branch would have split off, north-eastwards across Dartmoor.

Around that time I was lucky enough to visit a few times the Tavistock Junction signal box. The signalman was Fred Morrish, a friend of my dad’s.
