I don't see a difference, but...
This is a good game don't get me wrong, I've been playing the free version for a few years now and it's time I've spoken my thoughts on it. To keep it short here are some of my ideas that could be used for the game also I haven't seen a difference in the two games If you use the free version you have to pay for each of the characters in the item store With the pro version updates get released earlier Interactive cap buttons, switches and levers Customizable colours lights and horns More Interiors Door animation/s Optional malfunctions and events like breaking down or a car on the track crossing Passengers entering the carriages and sitting down Free roam to walk outside New routes A different way of changing train and stock A menu to pull up different buttons and switches for bells, whistles breaks alarms etc. An actual network of railway lines to properly have a route Being able to change to the second train Being able to set up an ai Smooth turns at the rail switches Missions and goals Optional time tables Multiplayer PC Available game Better creation mode That's what I have for now but here are some Personal requests A class 158 The X'Trapolis used in Melbourne, Australia Some kiwi rail trains Some Australian national Pacific trains Also V-Line trains Thank you and keep it up :)
