the reason being is during the delay of tsw 2 a small team had time to add the destination boards but only for bakerloo currently i'm sure they will add them to the german route and any future routes hopefully
And I've also heard that the destination boards are currently being tested and, if that goes well, that there will be on other routes too.
(PC user here). I've got to say, the passenger information boards on the Bakerloo line are possibly the best new immersive feature added to the game
