Back to suitable structures - this references a laser cut kit for Rueun in 1/150, though I can't see it on the linked website?:

Its a planned release - https://www.te-miniatur-shop.de/epages/79318808.sf/de_DE/?ObjectPath=/Shops/79318808/Categories/Gebaeude/Bahngebäude/Spur_N

Playing with a CAD design I am working on for HOm - printed a copy at 58% to see how the detail would hold up -

At this stage just a rough prototype but I do think it has some potential alongside the Kato Allegra.

It might be the angle Jim but the second floor windows look a fraction low against the Allegra roofline. Photos seem to suggest the Allegra roof is pretty much the same height as upper floor windowsills. How do the doors scale out for height in 1/150 as they do look about right but the goods bay door looks a little low.

I think its a combination of angle and lump of course track the Allegra is sitting on.

 

Goods shed aperture is 13.2mm tall which equates to 1.98m and would be about right. However - checking has made me spot an error, I have measured the door height from the stone plinth BUT looking closely, the wooden goods platforms are actually slightly taller than the stone plinth and the foot of the door is at the level on the platform. This means the door needs to be raised by the depth of the platform - https://www.google.com/maps/@46.6502446,9.723315,2a,28.8y,26.62h,72.91t/data=!3m6!1e1!3m4!1sdmWEXbEaQ9io87k1auOUOQ!2e0!7i13312!8i6656 looking back at the goods door you will see what I mean.

 

The personnel door apertures have a different proportion being a bit narrower and taller as the doors have fanlights above so they are OK, as are the upper floor windows, 27.75mm up which is 4.16m.

 

Maybe I should send you a 2nd draft to "proof read" !

It looks good and I suspect the print texture is going to work to our advantage on these for a nice scale grain :) 

I wondered if it was the angle but hard to tell so thought I’d ask :) 

Would be more than happy to ‘test’ them but equally to cover costs :)

Is anyone else going to the CMRA modellers day next weekend? 

 

I'm there all day, and intend that the primary focus of my day will be finishing the master for my Cargowagon single van, but I could bring along and show my two modules so far?

I’m nights so I won’t be able to go. Is another mini meet up at Warley convenient to those interested? I’m there with my HOm Harz layout so should be easy enough to find as it’s 34ft long!

The camera is not kind at this scale! Message me if you would like check it out.

Should have made the chimney taller.

Was discussing this project with a pal this morning who is interested - has a working standard for the modules been thrashed out yet or still in debate?

Still in debate after missing meeting up at Globalrail. I keep meaning to draw up some ends based on the discussion so far and throw them in the mix for debate. :) I’ll try to get on it this week and post some up :)

Based on the previous suggestions I’ve drawn three basic profiles, without trackbed at present, and mixed the bolts and clamp holes idea to come up with these. 

I widened the roadbed to allow catenary mast clearance. 

 

Ignore the tunnel profile but the red block is approx the size of the train. 

20mm grid

Catenary based on this

Here’s the full mock-up of the mountainous end. If we wanted a steeper front slope we would need a deeper base on this one but keep the alignment holes and the openings make it work with clamps too.

If we follow the Freemo type standard then there will be no set lengths. Generally we build end to end layouts in that, not circuits, where you can operate trains to and from destinations. The two threads below give an idea of what we are thinking of layout wise.

 

 

 Freem009, small setup realistically similar to what we can try in Nm9

 

 

Or Freemo once you get a big group, things like this are possible.

Look ideal from my perspective. Given that these are end templates and you are free to develop terrain between them, the 3 formers give all the variation you would need.

Looks good to me, good contrast between steep RhB scenery and gentle rolling RhB scenery.

 

Did you make a decision on board heights and gradients?

Not yet, got some ideas for the posts above but thought I’d throw the profiles in first then move on ;)

Experience of designing a sucessful modular system for the local N Gauge Group leads me to believe that the tracks need more of a bias towards the front. On the 900 x 400 boards I designed the centre line of the double tracks was set at 150mm from the front edge and on that basis I'd suggest siting the single track somewhere between 75 and 100mm from the front. I'd also standardise the ballast height at 3mm.

 

On a further thought why not produce blanks with the flat at the front and the steep section to the rear. You could indicate the other options with a "flame line". That way you get the maximum utility and flexibility from a single cutting.  Just a thought.

 

That's my two pennerth.

We did a modular layout with offset track 9” from the front and it’s fine if you’re just dropping boards in and out of a layout. With a true modular system though you need to reverse boards to fit in. With an offset track you then end up with odd offset shape boards that are harder to box up and transport. With a central track at least the modules are easier to handle and as we’ve discussed already we can use blank boxes for transitions where incompatible ends meet. 

Cutting along pre defined line is interesting as a cheaper way with just the trackbed cut as a hole and bolt holes?

Here are the two shaped profiles as rough mockups. The yellow dots show bolt hole locations. 

 

Whet do you think of the shapes? Do they offer enough mountainside etc?

Perfect!
