rail station
click 1 to select the station
click 2 to enter the train selection panel
click 3 to actually select the train
click 4 to drag and drop passengers
click 5 to finally start the train
totally 5 clicks, with 2 one-click simcash buttons very close, it's just ridiculous, seems intentionally made to loose time and money.
In the railway shop there are also buyable items that you can't use because the rail simoleon wallet is at lower level. For example the northwest railway is buyable at level 1 but requires level 12 to be used. The info about it is hidden you have to click on the object to see the unlock requirements, newbies don't know.
even the items available at the level 1 of the wallet doesn't work, for exemple you can buy another flying sim train, it let you spend the rail simoleon but you can't use it, you have to wait for some time, you can't start two consecutive trains.
this is clearly intentional people buy simoleon with real money and they are going to lose their simoleon in this way so they have to spend more real money.
