What do you guys think that the devs should add/update in the game?

I personally think that the devs should add the third-rail branch routes since we have the Class 350/1 which can run on third-rail. I also think that they should upgrade the track diverting section and signalling, especially at Leaton since we all had delays and SPADs there. More than that, I do think they should add the freight train feature because there are many freight ports around the map. But what do you guys think? I’m interested to hear you guys’ thoughts.
