Air Brake lap setting jumps BC from 0 to 17 psi (1.2.3766, AU NSW Great Zig Zag, Tutorial)

[RBHubbell]

Running Great Zig Zag tutorial activity #3
When applying brakes, move from running to lap and BC in all cars jumps from 0 to 17.
Entirely unrealistic. Unable to control train in any realistic fashion with air brakes.
Settings adjusted as suggested in tutorial guide.
Help!
Also, is there an active forum where issues like this are discussed for people new to OR?

[Peter Newell (coals-to-newcastle)]

This is a realistic feature for certain types of brakes that apply a minimum service reduction when first moved to certain brake positions.

A discussion could be started at Elvas tower forum (or one of the other forums indicated on the OR web site), or alternatively I can be contacted through the ZZ contact page to try and assist directly with any questions or issues.

Thanks

Peter

Thanks Peter. Zig Zag is fantastic bit of modelling. I'll contact you on ZZ contact page to discuss brakes issue. I'm in awe of what you have accomplished!
