Today I'm going on a train to Bristol. But that's not important right now. The interesting part is that claroscuro has created a new route to the station, which I'm going to use. It passes through both the Coral Park and Beehive shopping "centres" and appears to be the nearest I'm going to get to the Sangreal of a straight-line route.
It also provides me with an excuse to try out the route-plotting website that lnr found, producing this.
