Building bridges (and stuff)

Post by graymac on Sat Jan 28, 2012 10:31 pm

Making a few new objects for Ballyfeckin. This might be similar to some UK bridge work. The deck height is suitable to accomodate OHLE and the bridge is intended to be used in a cutting or with a road raised on an embankment.

Under it, certainly. It will be used in the next Ballyfeckin addition, where the main line will be continued beyond the Ferry Port junction near Waterville.

That looks suspiciously like that bridge the hopper train was crossing on that video. alien

And not only bridges - new track items and platforms are under construction. Most of this work is to allow stations and track crossovers on curves, as happens often enough. The platform maker utility cannot handle the extra faces needed for the bilingual safety markings on Irish Rail platforms, so it's all down to hand coding. Pics on celtictrainsim.com facebook page.

(as for a single 25m section of curved platform code, here's a sample - you can view the mesh in object viewer, no textures supplied)

And variation of the textures on the same mesh





Once you have made the "frame" it's often quite simple to edit the textures to provide variety. A house / shop can be "re-skinned" just like any other item.

Great row of houses there graymac, I can see what you mean but I'm still trying to see how to make such frames work as I have trouble with the vertex and face. If you could PM me some examples I'll work with them and see how to come up with a structure like this^^^^^^

Anyway another great object there and I look forward to some more great objects for ireland.

Regards

Have you seen the guide to mesh building on the celtictrainsim site (the "Eeejits Guide" series) - a lot of people have found it helpful. A pencil and paper is a powerful tool, sketch the vertex points and work out the numbering before you start the list. You cannot keep it all in your head at once.
There's plenty of buildings in the Ballyfeckin route to study as examples. Use 'F' key in Object viewer to see the mesh. The stuff shown here is "more of the same" really.

Dike time everybody!


Narrower than the other "main" dike object. Two sorts, with or without cable channels. Custom normals used to smooth transition edges.

Several locations over Irish Rail use catch rails on tight curves. So here's a 250 radius curve with one added. Not too difficult, though it is necessary to add a texture to the rail top if it is to look right.

looking good graymac Razz one noting though the brown rail isn't shiny really, it looks like the normal bottom part of a rail and maybe adding it's sleepers accelerates its realism. Just a note but you don't have to, i might try it myself in fact

The tightest curve on the mainline is a punishing 250m radius.
Think Drogheda, on the Baile Atha Cliath-Beal Feirste route (Dublin-Belfast). There are catch rails at that station on the curve.


Some curved platform objects grouped on the test route.

That's tight alright. The difference is the stock used on DLR and an Irish main line.The equivalent would be if you had, say, class 68s and Mk 3/4 rolling stock hammering up and down it all day?
Looks like some construction work still going on there. I'm working on a curved platform canopy to go with a station building like the one above.
An interesting job! Here's a start . . . . . .



The sections will need to be extended along the platform and offset in accordance with the curve, similar to the platform walls.

I love the really tight curves, we have some nice curves at Shipley train station.

Although i'm sure this HST with bogies would handle the curves pretty well Very Happy

I have no doubt at all! So a couple more hours spent, and I have a section ready for roofing. Shown here with plain wall, though station buildings will fit nicely. This is influenced by Drogheda station. The next extension of the Ballyfeckin routes will possibly be inspired by features between Killester and Drogheda on the Belfast line.

Looks fantastic graymac. However, is there a relatively pain free way of building curved platforms?

Thanks
