I agree that my first experience with track laying was a little frustrating. But now with just over 100 hours playing I am getting used to what I can and what I cannot do. Once you know how the track is going to ‘snap’ to which path, it becomes easier and easier.
Just give it time – I am on my fifth or sixth start and in this latest game am taking things slowly and not building up too many lines quickly (I have only used trains so far – after all it’s Train Fever not Bus/Tram Fever).
Have fun, enjoy the journey not just the destination.
