Would it be possible, when going to select a train, to include the ticket icon in the corner of the pictures of each route and train that have conductor mode available so it isn't this hard to find the services that have it? Also, when selecting a route, then a train, why do we then have to again select on which route we would like to drive that train? Oh... it would be swell if conductor mode on the Frankfurt Fulda line could be fixed.
It's not on which route the train will be driven on. It's substitution coming from other routes of the same train and some of them are better than others so you get the option to choose
