    Hello :)
    BUG REPORT
    Platform:
    PC / STEAM

    Game Version:
    Build 495 TSW 6

    Route / Train / Scenario Affected:
    ROUTE :

    RHEIN-RUHR OSTEN
    upload_2025-10-8_18-7-12.png

    TRAIN :
    Shunting locomotive DB G6
    upload_2025-10-8_18-8-46.png

    BR 185
    upload_2025-10-8_18-10-47.png

    Scenario :

    Hibernal Heaven
    upload_2025-10-8_18-18-52.png

    Description of the Issue (Actual Result):
    Once the double G6s are coupled to the broken-down BR185, following all the instructions given in the scenario.
    It is impossible to release the brakes when the train's front cab is activated.
    When the lever is in the “quick release” position, the brakes release very slowly, and if the lever is released, the brakes immediately reapply very quickly. (The brake release switch as a smilar result)
    The scenario requires the pantograph of the BR185 to be lowered, so it is no longer powered.

    Due to the brakes being applied, traction is locked.

    Expected Result (What Should Have Happened):
    The brakes are released and we can pull out the train.

    Steps to Reproduce:
    1. Follow all instructions in the scenario until coupling with the BR185.
    2.After switching the reverser of the front cab to forward (With the instructions), try releasing the brakes.

    Frequency:

    Allways

    Gravity:
    Medium
    (Prevents the scenario from continuing)

    Additional Information:

    I noticed that the handbrake indicator light is on, but the button does not work no matter how long I press it. (Release one too)

    I tried to reproduce the bug by changing cabins at the training center with only the two G6s, and it worked, but it was impossible in the scenario.

    If anyone has a solution or knows how to do this, thank you in advance :)

    Sounds like you having an empty main res. When the Main res drops to much and therefor also the HL drops a lot, you get the parking brakes applied automatically as they are dependent on the pressure in both, MR and HL. Question is why you get emptied out of air. Must be something with the 185 then. Maybe there is the brake valve open or something. Also be sure to have the train brake lever on the G6, that is coupled to the 185, in 0 position or it wont work.

    Thank you for your reply.
    I looked for the valves on the couplers, but they are not interactive.
    I tried release the brakes with the 185 decoupled, but still the same problem.

    Here are some media bellow that may be helpful.

    First you are a bit to much on a hectic path there. Be more patient. Don't use levers like rudders because it will get worse and worse with doing that.

    Then i can clearly see you HL is empty and thats why the parking brake will not release at all, not matter how much you will try it. You need to have the HL filled to 5BAR wo get moving. So, you need to find out why it is empty. In your video i can clearly hear from the 185 that it is releasing air constantly. So i would start there and check the cab and its state, pressures etc. The G6 itself seems not the problem, she is just reacting correctly to the situation with the open HL.

    Yes, you're right about the levers. I didn't want to make a 10-minute video, so I went a little hard on it.

    Despite the air leak detected in the 185, the G6 decoupled, the air still could not increase in pressure.
    I found air valves hidden in a hoods door that I thought were static.
    But that only released the little pressure that remained.

    After searching everywhere, I couldn't find anything, so I clicked on “I'm stuck” in the menu.
    The train was violently thrown off the tracks because I hadn't recoupled the 185.

    So I reloaded the backup and set my multiple unit settings again.
    I pressed “I'm stuck” after making sure everything was coupled.

    The locomotive didn't fly away, and I immediately noticed that the handbrake indicator had switched to release, so I could release my brakes again.
    I tried to move forward, but the weight of the train was so heavy that I ended up sliding backwards.

    I realized that, logically, the settings for multiple unit operation had been reset at the same time as the train.
    (Master, Slave, ect)
    After readjusting, I now had both units.

    The hill start was very difficult due to the weight of the train.
    But with the two G6s, I succeeded very slowly.
    I can now continue the journey.

    I am not marking the issue as resolved because, in my opinion, it is still a bug affecting 185 (it seems that before the reset, its Simugraph was not working).

    In any case, thank you for your precise help. :)

    I hope this will be resolved so that we don't have to use the “I'm stuck” button, which tends to do strange things.

    Since we never had any report about such an issue yet in over 3 years the G6 is out, i doubt it was a bug. That scenario does have a high difficulty level by purpose and any wrong usage of the loco can cause such an issue. An open HL is not a bug, it can only be a use error, at least on that consist.

    This was a quite difficult to drive scenario, but not impossible. You have to prepare the BR185. And then - sand is your friend! - accelerate the G6s with utmost delicacy up the grade. If I remember well, it took me 3 attempts.

    Yeah, it's made so that you have to control the slip with the engine power precisely or you will slide back. I also made it so that you don't need any sand, because it is called "brake sand" and not "acceleration sand" :)

    I like challenging scenarios so flagging this for a playthrough!

    Very well written out-of-the-box scenario, Maik! Very fun to drive.
    Of course I tried to be the smart ass and let the train roll back to a 0,0% grade.

    But who would've guessed: SPADed from behind. ROFL :D

    I followed all the instructions given, watched YouTube videos on this scenario, and no one else had the same problem I had with the BR.
    I kept this backup for several days until I could find a realistic solution, but nothing came up.
    I tried almost every brake setting.

    Later, the headlights and gauge lighting of the G6 have stopped emitting light despite the headlight texture being bright.
    It's still a minor bug, but the headlights are visibly on but not emitting any light source.
    I didn't make a report because I didn't really understand the origin of this one
    (Probably a random core bug)

    I would need to replay the scenario to see if it happens again, but for now I'm already on another DLC. :)

    Turns out I had actually already completed this scenario, ages ago!

    The ones that are currently an issue, preventing Journey mode from being completed, are the shunt moves where you eventually get stuck at a red signal and can’t get by it.
