It's PRETTY!
"Well comparing how good a default route looks like in RailWorks compared to a default route in TS2010 is kind of a no-brainer"
A matter of taste again, I'm inclined to agree with that but it's amazing how many don't. If Railworks wasn't so pretty it really wouldn't even be worth talking about in my opinion.
Funny thing, setting up AI traffic in RW you used to be able to spawn multiple trains from the same portal - but the procedure was pure insanity. Set a train on the track in front of the portal, attach a driver icon and give it a destination, attach waypoint instructions and set the priority and start time, then add it to the portal. If you want one train to spawn from that portal every 10 minutes for 4 hours, you need to repeat all those steps 24 times. And of course the last time I tried it, the portals generated more error messages than trains, the trains get confused and creep at 0.5 mph to the second signal, then vanish and reappear at the portal to try again, they stop at green signals and blow reds, collide with each other like kamikazes, I just can't figure how the AI "logic" would be acceptable to anybody.
I currently have a test session running in Trainz since 10:00 this morning - three portals, one spawning a through train from the south every ten minutes, one each from two north portals every 20 minutes, 12 trains per hour for 9 hours continuously, over 100 AI trains so far and it's still running. Portal north 1 drops off 10 cars in the first yard, runs to the second yard and drops off 10 more, heads for the exit portal. Portal north 2, a light engine MU, waits 10 minutes then follows him picking up the cars he dropped off. The player has the option of stealing some of the cars or adding cars to the ones that will be hauled away, thus adding realistic interaction with the AI trains, and it really don't take much time to set up and debug something like that.

But the switches are still ugly. :hehe: Ideally, get the Trainz AI traffic into Railworks, or get Railworks graphics into Trainz, you'd have the ideal simulator for me.
