You need to run the city for a year.
Not sure about the CTDs, the new networks can't be dragged like the standard ones. A fault of the game engine.
You have to download a tram station.
Have you checked the mod's documentation?
Good to know, I'll fool around with it for a little more.
I don't mind individual placement of the new networks. I'll survive so long as the system stabilizes. My question is, though, do you directly place tram-on-roads or do you lay down a road, and then place tram-on-roads on top of it? I tend to get a CTD if I do the former, so I'll have to stick to the latter, even if it's more expensive.
I'll look around for the tram station, it might be already installed and I just haven't seen it yet. I can't imagine they would put the tram lines in but not a station.

You can just edit the region's bitmap file (in the SimCity 4 folders) in Paint and add as many squares as you like. You just have to match the colors and make sure all tiles are 1x1, 2x2, or 4x4 for small, medium and large cities, respectively.
Imagine how awesome a proper patch or expansion would be. Yet EA gives us crap like Societies.
