Sorry for being a bit slow in replying - I was quite busy working on the FLUPs

... you will be able to use this T-RAM to visually get heavy Freight Trains in the middle of the road, and recreate California, or Virgina. You just need to have a way for rail to connect directly to glr, train generators and poof! And Chris, I am sorry if that is not what you intended, but your awesome modding gave us an opportunity that couldn't be passed.
That's fine. We did not intend this, but it's a game and if you have fun, why not?

Your discussion about heavy rail on road is interesting. In Europe, we had a few industrial areas with single heavy rail on roads, but less nowadays.
A bit more background on Tram-in-Road and Tram-on-Road: These are probably more of interest for Europeans. There are many European towns with tram, either with separate tracks or sharing the space with cars on roads. A good link page for tram photos is:
www.bahnbilder.de.
The textures of Tram-Road were designed by Schleicher68 and it took days of forum discussions with several trials. For me, the trams in Kassel, Leipzig, Nürnberg and Karlsruhe (all towns in Germany) helped to define the Tram-Road.
... I have questions about how stations are even possible for the (Tram-Road) networks.
There is not much space on one tile. In reality it's not different, like this photo shows:
Link (there is actually another traffic light behind the photographer that stops car traffic when a tram is inside the stop)
With the cars and tram sharring the middle of the road, which now means we can fit cars and sidewalks 4 lanes on one tile, does this mean we are close to a seperate 4-lane road network?
A 4-lane road on one tile should be implemented as draggable network, because it's a single network system. Tram-on-Road are dual network and presently we don't know how to make them draggable, therefore, these are puzzle pieces.
Apparently, a 4-lane road on one tile is not planned within the Network Widening Mod project, but technically, I believe it should be possible. It needs time to create ... or more people who understand the RUL's and can create new RUL's for draggable networks. Myself, I can't.
