With well-recreated interior views, the lack of a camera is a big omission. Experience with TS shows that switching to a view from the carriage while driving is possible without damaging the session. There are quite a few sections on the routes that do not require the active participation of the driver and there is an opportunity to admire the views from the carriage window. This function is extremely necessary. For me personally, it is more important than the conductor mode. I really want to enjoy the interior and the view from the window, but I cannot afford to spend an entire session in passenger mode.
