One of the scenarios on the tsw2 sand patch grade takes an hour plus to complete (endless switching if memory serves) but there are no checkpoints like other games have so making a mistake towards the end, means having to restart the whole scenario again from the start, which is extremely frustrating! Even saving the game doesn't help, unless I'm doing something wrong. Next time you load up the game, it starts the mission again at the start! Can this be considered for future updates please, perhaps for *all* missions, trains etc or at least a way to quicksave/load from the point saved rather than simply the start of the mission? Whilst I'm here, any chance of some more routes for the underground please? I enjoy playing the Bakerloo line but would be great if there were others, too.
