The Reverse Engineering scenario on Boston Sprinter with safety systems turned on is quite frankly an appalling experience and a scenario I don’t think was tested at any point with safety systems turned on. The scenario took 1h 10m to complete from start to finish. The screenshot below says it all really. The scenario expects you to go from Boston South Station, around the reversing loop and back into Boston South Station in just 6-minutes, which is an impossibility. As you can see, it took me 29 minutes to achieve this. Part of the reason is the 5mph speed limit, but a major problem is that ATC/ACSES kept going down to 0mph causing an immediate brake application. ACSES also remained at 0mph for large parts of the reversing process. So, instead of getting into Boston South at the expected 10:41am time, I arrived at 11:09am. Oddly, I still earned a gold medal, despite arriving back at Route 128 some 27 minutes late. I did NOT enjoy this scenario at all.
