As part of this blueprint I have re-inserted coupler indication back into the FORCES INFORMATION HUD as per the attached screenshot in the column to the right of coupler. It will show whether the coupler is in PUSH or PULL, or whether it is OVERLOADED.
I can understand the issue raised with long trains, and agree that it would be nice to have some sort of scroll feature on this, and the other HUDs, however I am not familiar enough with the code to make these changes, and am happy to hand any scroll type changes off to another developer.
If no one is able to look at the scroll option, then perhaps a work around would be to have a "Short/Long Train Display" check box in the options menu. In the SHORT mode the display would show every car in the train, as is currently the case. For LONG trains, the display would display, say every 3rd car.
The addition of the "Short/Long Train Display" check box is
not my preferred option, as I personally believe that we have far too many options in the options menu, however it depends the alternatives that are available and the support that it gets.
Please note that this change is currently not available in the Beta build at this time.
