Ho scale catenary

[Lavae16]

Hello everyone in about to start working on doing my layout but before I started I wanted to create catenary for when I'm finished all of my track work but needed to know for a ho layout what type if wire to use what size mm wire and possibly what site I can order off I'm not trying to use the marlin style As it not the style I want to attempt to make my layout will be based on philadelphia amtrak keystone line and me corridor but needed some help if any input can be given or would help very much thanks

LION thinks that steel welding wire, the kind sold on spools might work for the wire, and for the brackets etc. You could use heaver 1/16" or heavier wire for the uprights. Even if you are mediocre or better at soldering you should be able to fabricate something.

If you are looking at the prototype area I think you are, you're planning to put a spiderweb in the sky over a puzzle palace of fancy specialwork.

Murphy's paradise!!!

My own catenary motors are models of 1500VDC (not 11000VAC) prototypes.  Even so, the contact wire (in 1:80 scale) comes out AWG #30 - WAY too light for one of my heavy motors with its pair of amp-hog open frame motors.  #22 wire (the smallest I would consider for the service) ends up looking more like water pipe than contact wire.  There's also the matter of wear - pantographs make sliding contact, and heavy traffic will guarantee that both pan shoes and contact wire WILL wear.  Replacing pan shoes isn't much of a problem, but rehanging the overhead???

My solution, endorsed by armies of Japanese modelers, is to model 'virtual' catenary.  The support structure, tensioners, substations and main power lines are present and accounted for - but the contact wires and their supporting cable aren't.  Standard two rail power distribution/control means that the system can also handle steam and diesel locos without issues.  Access to the track is infinitely improved, as is the ability to correct derailments if they occur.  Even applying the Shop-Vac to the layout is less fraught with danger.

People HAVE built 'hot' catenary, and operated their models from it.  I see no valid reason to emulate the feat when there's a less stressful approach available.
