Not sure if its me or the update from the beginning of June but the page up/ page down selction of braking regimes on these locos eventually causes the brake pressure needle to disappear, the pressure to reach a very large negative number and the brakes to lock on. Starting as a passanger setting works, but starting as goods in th emogul locks on straight away. I think its a scripting issue but these are such complex scripts its hard to see how to "lock" this option to basic coaching stock settings
