tanawat8814 Posted December 2, 2023 Posted December 2, 2023 After stopping at the station and opening the doors, the pantographs somehow lower and cannot be re-raised. Hence it is impossible to continue the schedule. Disabling / Enabling the battery, de-activating / re-activating the cab, etc. all have no effect.
tanawat8814 Posted December 4, 2023 Author Posted December 4, 2023 A follow-up on this as I believe there is a bug, but it arises from a specific action. When stopped for an extended period, I believe it is common practice to raise the front pantograph. I followed that procedure at Katowice with no issue. However, doing so at Sosnowiec Glowny is what caused the train failure. I repeated the procedure today and, viewing from the outside, observed that attempting to raise the front pantographs (F key) actually caused the rear pantographs to lower. There is something specific to Sosnowiec Glowny that causes that anomalous behaviour since, as stated, the same action at Katowice resulted in the front pantographs being raised as expected.
tanawat8814 Posted December 11, 2023 Author Posted December 11, 2023 A further follow-up after more testing. The issue seems not to be related to the location, but rather to how many times the front pantographs have been raised / lowered. 2 or 3 times seems fine but on the next attempt, the rear pantographs go down and there seems no way to recover. 1
chromatix Posted January 1 Posted January 1 That sounds very much as through you're running out of air pressure. Did you enable the converters and compressors? On this train you have to do that by hand.
tanawat8814 Posted January 2 Author Posted January 2 No, I just tried again. You can check yourself without having to do the whole scenario. I set up the cab, double checking that converter and compressor were on. Rather than starting to drive, switch to outside view (move to see all pantographs). Then: F to raise front panto (works correctly) Ctrl F to lower front panto (works correctly) Repeat above sequence a further 3 times (all work correctly) Now try a fifth time to raise the front panto (F) > causes lower pantos to drop with no obvious way to recover. In case you are thinking it is unreasonable (too much air load) to test in this way, I should add that when I came across the problem originally, it was after trying to raise the front pantographs at a station stop. There had been plenty of time for the air pressure to replenish.
