I am kind of curious as to the method by which catenary like Dutch Catenary is able to alternate pylon placement to be every 2nd tile. Dutch Catenary seems not to have its sources on devzone, and I couldn't find a dedicated forum topic for it. NML documentation mentions that there is a callback for catenary pylons, but doesn't explain how this may be selectively used by tile, or really mention any interesting features for catenary for that matter.

Further to learning how this works for railtypes, I am curious as to if it is also applicable to road and tramways, with or without NotRoadTypes (for example, can regular tramway have pylons every other tile)? Beyond that, is it possible to place pylons every 3rd or 4th tile?

Thanks!

Isnt that "normal" behaviour of the game? AFAIK all railcatenary has this behaviour and AFAIK all catenary sets are just simple graphics replacements. You can tweak the position a little bit (move it closer or further from the rails), but that may eventually result in glitching or problems with catenary on bridges.
Turning pylons off is AFAIK only possible for stationtiles (and waypoints), maybe that is the callback what the NML documentation refers to...

Therefor I think this can only be changed via a patch and not simply with a GRF.

Because I think pylonplacement depends on the x/y-position of the tile in the game. I believe that determines when and where pylons are placed, at least for the position along the railway (leftside/rightside). But maybe also when a start/end-tile of the line gets 2 or just 1 pylon on a single tile:

Maybe the devs can clear this up a bit more, about how this actually works. This information may indeed be handy for future patches (so, like making pylons get the same behaviour like signals, where you are able to control the spacing and left/right position. Maybe not exactly like signals, but a setting that you can set before starting a game, or railtype dependable). Or even making it possible to get pylons on both sides of a rail (making it possible to get gated catenary).

If this is possible at all (a big "if"

), I can imagine that it may take a while to work this out, however if this behaviour is the same for roadtypes, then it may be interesting for the developers of NotRoadTypes to look into this for tramways....

Thanks for the insight, although it is starting to bode less well for applying this concept to tramways. Tramways have a set of sprites for catenary 'rear' (positioned behind vehicles) and 'front' (drawn over vehicles), but as far as I can tell, there is only one sprite in each for \ and / directions, and no separate sprites for pylon and wire - meaning it would be impossible currently to automatically omit a pylon on some tiles.
