One of the unique features in Train Sim World 2 is the ability to walk around, a feature which I believe could be used more. This extra use of the feature would be adding a seperate timetable for train depot's on routes for various stock getting moved around the site during the day and night. This would mostly be welcome on some of the large depots in game such as Old Oak Common, which always seems to be too empty compared to what it's usually like, although this could be down to the incredibly empty GWE timetable compared to real life.
