A little feature to increase the immersion of some trains would be DOO screens that turn on when stopped at stations. These wouldn’t be live but work in the same way the platform monitors work on the Bakerloo line. You could either take unique screenshots from each camera position on the train of each station or you could try and take an ambiguous shot of one station and use it for the rest on the route.
yeah, it would be nice, and not only on UK routes, if they found a meaningful purpose for those inactive screens... since they cant display IRL information that would be on them (many German/Austrian trains have Ebula/Fahrplan on them e.g.), they can put sth on them... cos now it is just dead screens doing nothing
