Hi Joe,

 

I think that there are two additional vertical supports above the overhead wires. See the photo below. Actually, each line has two wires. The top wire has the shape of a catenary, it is only there to support the bottom wire which is in contact with the train's pantograph. I think that this vertical bar is called "vertical isolation bar", it is meant to hold the catenary wire (which lays on top of the two black cylinders), and it also maintains the distance to the registration arm constant and stable.

 

 

I have designed and 3D-printed a few of these for my layout last year, but I need much more and there is so much variety. I can share the files if it's useful.

Seems like those fold up connectors to the rod may end up being more bulky looking than just the whole part etched. Getting to these sizes getting perfectly scale may just be a bit too hard, sometimes small details at scale are so small they disappear at a foot so enlarging a tad makes them more noticeable saying what they are at normal viewing distances. I get it that many want things spot on, but we look at things in not usual distances on our models usually and to make it look right to the minds eye things need a tad of fudging sometimes.

That's a good point. I will still test one out of curiosity, I will also test the flat etch version.

There are the two supports for the upper wire (is that what is referred to as the messenger wire?) on the 2D drawings, I just haven't included them on the 3D model yet. These should be pretty straightforward to make as they just drop straight down with couple of insulators to isolate the wire.

That is a lovely piece of work! I totally agree about the amount of variety. There seems to no end to the amount of variation. Thank you for the offer, if you are happy to share the files, it cannot hurt to have more information.
