This DLC adds the snow weather effect to the northern part of the map you are playing on which provides an extra challenge to overcome as the snow slows down your engines.
This is the best train company management game I've played in a long time. I was a big fan of the Transport Tycoon (DOS) and TTD games and Sid Meiers Trains was a favourite also. In my opinion, this game takes what was great about those games and expands on it. The controls take a little to get used to, but once you do they are fine. The graphic quality is a decent compromise between scenic and lean enough to run on a slow PC (I can run it on my old laptop with Intel graphics on Linux with settings down which is nice) yet when turned up on my desktop, it is nice to look at. I bought on sale for around $22 AUD and at that price, it is a bargain. I have bought a couple of DLC's and will eventually buy them all as I can appreciate the attention to detail in this game. The other reviewers claiming that you can't specify train routes or choose different ways for a train to arrive are either reviewing an outdated version or didn't know how to do it. You can create waypoints on sections of track to tell trains which track to take on their route, you can specify which track in each station that each train should use, you can specify what cargo is preferred or blocked, you can set up signalling so that tracks can only go in one direction and much more. It is definitely worth buying if you love train games and a big bonus is that it works on Linux out of the box.
