As I am getting more and more acquainted with Open Rails, I noticed some problems with the default HHP-8 locomotive, also presuming it won't be the only default engine. This coincides with my increasing interest in MSTS scripts. Coming back to MSTS (really just starting "seriously" for the first time), I want to ride the default trains on the default routes in default activities 
Fixing the default scripts for my personal pleasure, I figure, is a good starting point for learning, and maybe I'll be able to contribute to the ORTS community in the long run.
Onwards: ORTS interprets the ENG files more rigorously, that much I gathered. One effect is, that the HHP's air brake release is awfully slow. From what I've read, the extent to which this is experienced is not realistic. There is the ORTS correction of "questionable braking parameters", but according to the manual this is limited to single pipe brake systems.
Among the advice I read was (the problem being a slow pressure recharge):
So for these kinds of problems, I thought maybe there is a consensus as to where the root cause lies, hoping the problem with the default engines can be tracked down to a few usual suspects...
Also, the HHP is supposed to auto-bailoff, but does it also from a stand-still, i.e. after starting an activity. Is this supposed behavior?
Have a good week you all!

Among the advice I read was (the problem being a slow pressure recharge):
- increasing the Psi/s charge rate in ORTS options:
from my understanding the worst solution since it ought to be a realistic setting as is, best left untouched? For instance, the Acela Express engine already recharges pretty fast (mind you I don't know if that is realistic either) - increasing the brake release rate, e.g. from 5 to 20
- increasing the main reservoir, e.g. from 10 to 30 -
the reasoning I do not understand - and shouldn't the reservoir stay fixed at 140 PSI, the real world figure?
