The cruise speed is set, but the locomotive accelerates until it exceeds the cruise speed without applying braking, even if the cruise speed is lowered (This occurs only in the second cab of the locomotive)
Apparently this is an ongoing issue with all versions of the 185 from what I've read, Afb works properly when driving from Cab 1 but will not hold your set speed when driving from Cab 2. DW
It's just been introduced with the last TSW4 patch (yes, TSW5 is the same game with added elements and patched UI). Supension update broke it, and as far as I can tell (messy forum and wild posting all over the place), it hasn't even been confirmed officially. DTG tend to just sit out things often.
Ok, I was confusing it with the now completely broken Salzburg 185, that was broken by the suspension update: https://forums.dovetailgames.com/th...-power-in-mission-kt-41810-in-salzburg.83673/ Both cases unconfirmed by DTG. I'm not sure if there's a 185 left that's without bugs (another one has the taillights on permanently)
