Question: Is there a way to stop the game from greying out my pillars when using the Tubular Silicon Bridge?
The three different tubular bridges share sprites, the pillars additionally among track types. The sprites are just re-coloured. As such it is not easily possible to change that unless you change the other two bridges, too.
My best guess is to keep them and adjust your maglev bridge such that it matches those... though they differ slightly between base sets. So you easily end up with glitches here and there unless you rework all those sprites, but it may work with pillars without glitch. Chosing one or another version for the two different base sets via parameter is for MP games no option as it'd be wrong for at least 1/3 of the players (same unfortunately with tunnel sprites, even with rail types, but that can be worked around).

Thanks Ammler! I'll keep your offer in mind. I have a feeling it'll be slow going for my slow internet though.
Single updates to a repository are usually not large and as such very quick; it'd give you also the possibility to produce nightly versions, catching some errors and glitches possibly faster.
Concerning trains I indeed consider it the way better approach to keep tracks and vehicles separate entities / newgrfs and not mix them, if not necessary.
