Obviously itíll depend on which material you use, but something like Shapeways detailed plastics (FUD, FXD) are very brittle, Iíd not want to use that for any masts thatís were ever likely to get bashed, or Iíd make them easily replaceable, much like the Dapol ones.

Not sure about that anymore... check this out:





Sure you've still got to be careful, I'd say you couldn't bend it like that a near a right angle but it's still pretty resilient.

Oh, forgot to say, that bit I'm bending is only 0.6mm thick!

Hello

I reckon you could 3D print some if you wanted to go down the DIY route or perhaps look at using metal H section for the main post and then creating etches or 3D prints for the arms and smaller details. It's easier than you think.
I saw an article in an American N magazine a while back by someone that built American catenary in N with just some metal H section, various gauges or wire, some plastic insulators and metal glue. The results were very good.

With any hand-made catenary you'd have to be careful cleaning the tracks or make it easily removal but 3D fine detail plastic is actually quite flexible and you could create exactly what your prototype demands if you scratchbuild.

H section is not realistic for most German overhead. The Germans mostly use lattice post or concrete spherical posts

True in principle. However creating/sourcing lattice work from scratch is going to be very taxing. My view is to create an overall impression of there being masts, as opposed to specific accuracy.

There are always exceptions to the general rule such as in this photo on the Moselbahn.

Exactly! And quite long sections of Swiss catenary are done with simple H-section masts and cross-spans. It's quite good enough to get the idea across IMO. For me the main focus is the trains. Matters such as signalling/catenary etc. just paint the backdrop and context.

I remember where I saw a N scale catenary scratch-building article now. When I lived in the States I used to read N Scale Railroading magazine. In the Sept/Oct 2012 issue, there is an article on home-made US style catenary: http://www.nscalerailroadn.com/073/NSR073.html.
Looks like it's still available as a back-issue if you were interested.

It's a fairly straight-forward article but it mentions a few products and tips that might be useful to you.
It's also a brilliant magazine, very inspirational.
