The AI Acela express services dont show up when driving any other train or on foot. The derparture screens still say its there but it never appears and is absent from its usual depot location. they only show up when selected as a service Here are the pics of the yard at the same times, one on foot and the other when starting a service on the Acela
Looks like the Acela layer isnt properly set up as a DLC layer it seems, it doesnt mention its from a DLC in the layers menu while the ACS does
Same issue on PS5. You can select the Acela as a player train, and you will see the AI Acelas if you are in an Acela, but if you are in any other train they are completely missing on the route. The Acela arrival times even still appear on the PIS at Boston but the actual trains never show up. I reported this week one, no fix. This route isn’t getting great post release support because some of the other blatant stuff (ie nuclear explosion brightness headlights on the F40) also haven’t been touched.
