B Set for MSTS - sudden emergency brake at 74km/h

 
  aside8 Beginner

Hello everyone,

I've had issues relating to the B set by Chris Jennings available from Coals to Newcastle. At exactly 74 km/h, an emergency brake will apply and only release when the speed is back at 0. Is this a feature or a bug, and if it is a bug, can I fix this?

Thank you all!

IT sounds like a bug related to the overspeed settings. It's a looooong time since I messed around with MSTS, but if you go into the ENG file for the B-Set you should find code that looks like:


OverspeedMonitor(
       MonitoringDeviceMonitorTimeLimit( 0 )
       MonitoringDeviceAlarmTimeLimit( 5 )
       MonitoringDevicePenaltyTimeLimit( 0 )
       MonitoringDeviceCriticalLevel( 151 )
       MonitoringDeviceResetLevel( 0 )
       MonitoringDeviceAppliesFullBrake( 1 )
       MonitoringDeviceAppliesEmergencyBrake( 1 )
       MonitoringDeviceAppliesCutsPower( 1 )
       MonitoringDeviceAppliesShutsDownEngine( 0 )
       MonitoringDeviceTriggerOnTrackOverspeed( 1 )
       MonitoringDeviceTriggerOnTrackOverspeedMargin( 2 )
       MonitoringDeviceResetOnZeroSpeed( 1 )
       MonitoringDeviceResetOnResetButton( 0 )
       )

I would suggest trying to change the "MonitoringDeviceAppliesFullBrake" and "MonitoringDeviceAppliesEmergencyBrake" parameters to 0 and seeing what happens. A quick look shows there's 3 ENG files, so you might need to confirm which consist they relate to and test that specific consist. Or you could do it to all 3 END files and see what happens.

Doing that should stop the penalty brakes, but you may still shed all amps until the speed is back to zero. Test and verify. If that is the case, change the MonitoringDeviceResetOnZeroSpeed and MonitoringDeviceTriggerOnTrackOverspeed to 0 as well.
