Map (at least in Rapid Transit) lacks stations names. I would also suggest adding distances, timetable (for selected service in service mode). Destination of other trains on the map would also be a nice addition. Making something on the map clickable, more interactive would make it more alive. Now it doesn't provide almost any useful information.
Great suggestions. Hopefully, we'll see game improvements, such as what you mentioned above, implemented in the near future. TSW has a ton of potential but it's only been out for about a year now. It'll take time, most definitely, but we'll have to wait and see what DTG has in store for us. It'd also be great if they could give us some sort of road map as to what they'd like to implement within the span of this year, without revealing any DLC route-related news.
