This is one fine piece of DLC released by virtualTracks (do note it was not made by DTG nor RSC), the map contains a lot custom builds and very high quality stations. Of course every TS game have issues, so the problem with this map is that it is no longer maintained, not even updated. DO NOTE, THE MAP IS NO LONGER UPDATED!
But, there is a good news, the creator of the map releases third party upgrades for the map with his website that you can download to upgrade the track and fix a lot of oustanding issues and to add QuckDrive capabilities.
Other then the major issues with the upgrading process, the second problem is the quality settings that we are enforced to abide by else we won't see sections of the scene that is right before us. Some users have to set their settings really high in order to be able to see certain builds and bridges, this can of course cause issues for most of us with mid-range PC's.
So yeah, I'll rate this 9 out of 10 just due to the upgraded LZB system, quality of stations and the scenery that feels really nice. You can go and buy it at any time but I would recommend to buy it when it's on sale.
