@planetmaker: sure these don't look like any OpenTTD bridge, but since these will be objects I figured I might do whatever I please

@CheesePlant: There's a release with the two tracktypes on BaNaNaS since yesterday. You cannot place track over the top, but you can use the convert tool to change them in a different track type.
@Snail: I left the fences as is for now. I aim to draw some old fences, but will also add a parameter to remove them completely.
