Catenary Line's

Does anyone know of a track that already has the catenary attached to it. It would be great to lay one spline and have both the track and the catenary placed.
 
Have done that, keep backing away from uploading it (and required poles and other support structure). It's not real catenary, mind: I know of no way to model the actual catenary swoop of the support wire, or straight segments for curves as the real thing demands... and is such a pain to model!
 
OK, with that motivation... here is what they look like:

You can see the deficiency on curves, but with a little imagination... (g)

and a span wire span for multiple tracks, set up for 5m separation:

I'm attempting to upload the basic parts to DLC, they will appear in Freeware if that is successful (no promises!)

Caveats: The track is not up to modern standards with points, frogs, etc., and this is a highly simplified representation of the subject with a common contact wire height. In the real world, catenary support wire forms graceful suspension-bridge curves (hence its name) and the contact wire does *not* exactly follow the track centerline. First, because except on perfectly straight track, it physically can't and, second, if it did it would wear notches in the pantograph contact shoes... so it intentionally zigzags back and forth even on straight stretches.
 
Hi guys,

Just a note relative to the curved effect :
in France, there was a catenary system, developped by one region of the SNCF network, which had exactly this special effect . Is was called the caténaire MIDI (MIDI was the name of this region, in South-Ouest of France) . This gave to this system a gracefull aesthetic :) !

You could use this track: <kuid:394799:100754> DMT Pro TRACK V2, Faded Wood, Light Brown Ballast, Rusty, Crest both sides. It also comes in two track and 4 track versions:
<kuid:394799:100373> LLT 2 Tracks with 5M Spacing
<kuid:394799:100374> LLT 4 Tracks with 5M Spacing

Yes, you would need to change the associated track KUID to get the overhead wire, but would then be able to use poles (a trackside asset) and span wire (a scenery spline). I've done that with an older multi-track asset and it works OK, though being very old (TS2004?) it wouldn't accept TS2009+ track. I like the fabricated poles in the picture, they look a lot like New Haven single track catenary supports.

I looked at the asset that I Downloaded today, and it is great, but I didn't see the "associated track KUID" when I opened it for edit.

The basic set for my system is on DLS, and I'll describe it in Freeware forum shortly now it's up and available.

I believe those multi-track systems work differently from the now-obsolete multi-track assets, so my mistake for thinking you could just change the track asset on them (or hook up a different track type as with fixed track). There are several ways to address the multi-track problem in Trainz, and they pass in and out of favor over time!
