Thanks for the post, I am still playing with this, unless you are interested in republic of ireland or the UK national rail network, there's not a great deal of map yet to explore. I hope though that anyone knowledgeable about trying to do this kind of thing can appreciate where we ae going. I need to tweak the merging, and also get a lot more of Europe back on (I have rail stuff for western Europe and a few national bus networks) in order to demonstrate the merging better. The thing with this stuff is when it works you dont notice, but when it doesn't you end up with a big blob of uselessness. The point of blobbines and uselessness of the map comes very quickly with a metropolis as you can imagine. You cant even do a map of just Paris, which has a bus on seemingly every single backstreet in town, until you get this to work.
