It looks like somebody had an epileptic fit whilst drawing the route. Probably be a decent drive with good variation though.
Matt talked a bit about today in the roadmap stream. In short, this is a "network" kind of route where you have many short services that go from one place to another (none of them goes side to side of the route), but there are a lot of them connecting the different places. AFAIK, this is the first DLC of this kind. I'm quite intrigued and cant wait to take a look at the preview stream when it comes.
I think Cathcart is actually considered the first “network” style route, albeit seeming a little smaller of a network than this appears to be, but a network nonetheless
Cathcart is the first network route, but it has the circle that can be considered the main route and then you have the 2 branches around it. Glasgow Central is the main hub and pretty much everything starts or ends there. You have the option of doing the circle that does not cover all but kind of feels like doing the whole thing. If I understood it correctly, Cardiff will be even more decentralized (might be wrong as I'm not familiar with the zone). You have Cardiff Central but there are no circles around it or a main route, just small services between the different places and quite a number of them will not go thru Cardiff Central (ie: 7↔15 or 1↔11 in the map posted above). This is what I think is unique and a first in TSW.
This route is by far the one i'm most excited about, a proper varied UK network using diesel only traction, i know it's probably a fair few months away but i'm so happy this is coming to tsw!
