I have seen quite a number of gameplay videos of this, although I have not bought it myself (I watch the videos while I am waiting for code to compile, or waiting to see whether a Simutrans server/client will desync, so I have seen a large amount of game footage by now); I get the impression from them that it is a little like a simplified version of Simutrans-Standard with more modern 3d graphics, but a much smaller range of vehicles/terrain/buildings. The balance seems off to me (electric railway locomotives cost more to build and run than steam railway locomotives, for example; freight appears to make little or no profit most of the time, whereas passengers can make huge profits), and players who have set up railway lines that are essentially a giant circle of the whole map (which is small in terms of what Simutrans can do on modern computers) seem to have done very well in terms of profitability, which suggests that passengers do not care how long they take to get where they are going. There does seem to be a system in which vehicles get old and wear out, which is in principle a good idea and absent from Simutrans (both Standard and, at present, Experimental), although I have not seen any footage where it is clear what, if any, impact this has on gameplay.
Having watched videos rather than played it, my ability to comment in detail is limited, but I get the impression that it is the sort of game where a player can succeed in the game's own terms (i.e., passengers/goods transported, money, towns growing) by producing quite unrealistic and (in real world terms) inefficient transport networks.
On the other hand, it does look quite good graphically (except that the terrain is a bit bland) and the tracklaying is reported to have been improved a lot from Train Fever, with this appearing to be quite easy and intuitive, producing realistic looking results fairly easily.
Time also appears to pass very quickly.
