Xbox Series X "engineering Interruption" On Isle Of Wight

Is it possible to complete the "Engineering Interruption" scenario on the original Isle of Wight?

I get to the end back at Ryde Pier Head, but somehow I can't set the master key lever to "off" because it's sort of invisible. I am able to set the master key itself to "off", but then I miss a step and cannot complete the scenario.

Any ideas?

 

Was your reverser set to off as well? Did you make sure to turn off the master key lever and the master key behind your seat?

 

Yes, I definitely went through the usual process to shut the train down, and in this case you get step-by-step prompts on what to do as it's a scenario.

Might be a one-off. I'll report back next time I try the scenario if it happens again.
