OR sets default values everywhere. So they are only redundant only in case you want to set the same parameters as the defaults are. In this case you may omit them, obviously.

There are cases where a coupler is not required by the activity and this default action makes the activities in question unplayable.

I have here a case in point about OR subbing in defaults for "missing" parameters. The engine here has a vacuum brake, the wagons handbrake only.


This consist will not run in OR because of the subbing in of default airbrake parameters that are not needed. MSTS also subs in missing brake system parameters but does not go as far as OR in that all wagons with handbrake only have a 0kN brakeforce when brakes are applied, and the braking system allows release, unlike OR which is placing all wagons into Emergency.

It was common in the UK until at least the 1970s to have non-braked stock running in freight trains, some were partially fitted with a braked head-end and non-braked rear. Therefore until this subbing in of defaults is fixed many UK activities that use stock with handbrake only will not run.

Mervyn,
I don't promise anything, but can you provide a download link for a wagon of this type?

BTW, have you considered the "Include" method (see paragraph 8.14 of the manual) to insert the desired values of the missing brake parameters, without affecting MSTS operation?

Your rolling stock seems to be misconfigured. You must specify

BrakeSystemType ( "air_piped" )

or "vacuum_piped" for handbrake-only rolling stock to work properly.

Thanks Peter, that does the job perfectly. There is no mention of this in the manual. That just leaves the coupling problem to sort out.

[gpz]

You are welcome. :) This function is MSTS compatible, and not OR specific. I'm not sure if all MSTS-compatible settings are repeated in OR manual.

[copperpen]

There is a difference here between MSTS and OR. In MSTS, if you omit the BrakeSystemType, it activates an air brake system, but with zero brakeforce. OR on the other hand is different and does what you see in my screenshot, so an entry to this effect in the manual would be welcome.

[gpz]

If this is the case, then OR might default to "air_piped" brake system too.

One more thing about brakes that needs to be addressed:

Long ago, a look at both Kuju's MSTS techdocs and Rudolf Richter's .eng/.wag file manual would suggest vacuum brake control parameters (ejector, etc.) are exclusive to steam locomotives. Obviously in reality diesels and electrics in the UK are indeed vacuum-equipped, but I am wondering if this oversight has been corrected (or intends to be corrected) in OR. Has it? Will it?

I don't know much about UK, but I cannot believe this statement may be true.

There is no difference in OR how vacuum brakes vs. air brakes are handled in rolling stock, being it steam or non-steam locomotive.
