Need Help With Catenary

[westaussietoo]

I'm having difficulty laying catenary on a British route on TRS06. Can't quite get the hang of it and the manual doesn't help me. Also I find what I have been able to do is too high for the pantographs. Which cat in the spline section of surveyor is best to use? Any help would be a help. Thanks.

Which Catenary type are you using?

I generally use UK 50m and UK 25m splines. Occaisionally I use 'Catenary Single/Double/Double center 40m splines. All of those catenaries are built in assests.

Good luck with the electrics.

Hi Mitchey, I just tried using Cat 2CW 20M because it happened to be the first on the list. What does the 20, 40 etc Meter designate? I'm assuming it means there is a support put down every 20 (etc) meters. Also, how does one get the right height for the wire?

 

[Mitchey]

There are 2 heights of catenary:

A standard
A lower
(as I like to think of it)

I steer clear of the first Catenaries in the list (the 2CW ones) (they confuse me)
The UK catenaries are lower catenaries, and the othe catenaries (mentioned above in my previous post) are standard.

The number (in metres) has nothing to do with the height, but instead displays the approximate length between the catenary posts.

Happy to be a help,
Mitch

It's up to you there are some UK routes out there with the higher catenary I use modern ( high cat )as I found it has a good range of items for use some are very limited in content some complicated to set up.I would spend more time setting up cats than actually laying the track as it's virtually mirror imaging the track if you want to get it right & look reasonable.

Catenary is laid the same as track in a spline & varies from single up to about a 4 track width. In single pole single line,Single pole double line,centre pole outer lines,outer pole inner lines plus splined catenary bridges & wire holds etc,you need to pick what suits best & where.

Download the Catenary Height Tool from the DLS (CMP won't see it it's for TRS2004 ) just go to download page non the DLS & click download CMP will do the rest( it will end up in trackside objects ) This is used to centre & height adjust the Catenary.

Place them along the track ( they can be slid along the track to suit )then lay the Catenary alongside the track the move the Catenary into place .The top of the gauge has two raised notches this is the centre & height for the low UK cats position the top wire into the groove at the pole positions.For the heigher cats position the lower wire the same way.

Unless your on a grade the heights should be pretty good if not adjust the cat spline points up/down to suit the gauge.

When you come to crossovers end of track etc there are poles without wires attached as well as wires without poles weight poles end of track poles bridges wireholds use these to complete a crossover end of track etc

Have a look at a couple of electric routes save them to a new name & pull them to bits & have a look at how there put together If you find one you like note all the names of the bits used to make it up,it saves a lot of time.
