It is. It’s been like that since the route was preserved and Adam hasn’t got round to Peninsula Corridor yet, such is the slow progress of things.
Same issue on PS4 Pro. I bought the Collectors Edition last year an the sound was there the most time. Sometimes the sound did cut out but could be brought back by standing up and sitting down again. Now there is no engine sound anymore at all. I guess any of the updates did kill it.
you might try to shut down the engine and do the engine start-up procedure. It worked on PS4, and i follow the procedure by default. It will delay my departure, though.
Thanks, that worked for me on PS4 Pro. Hoping that this issue gets resolved with the upcoming preservation update.
