SurvivorSean Posted December 15, 2022 Share Posted December 15, 2022 So I had some help from my chat to get me through some of the things. I eventually got going and all was going good until I slowed down. It brought me to a stop quicker than I expected and then I could never get going again. If anyone can help this would be a good learning experience. It's towards the end of the 1st hour. Link to comment Share on other sites More sharing options...
Solution Gazz292 Posted December 15, 2022 Solution Share Posted December 15, 2022 the right hand gauge isnt reading where it should... it looks to be way over at 1.6Mpa, that's the main pressure i believe, it shouldn't go over the red line at about 0.8Mpa. Not sure how you'd correct that... the safety valves on the compressor and tanks should have operated a little above 1Mpa or so, : i had accidentally turned the compressor off once flipping switches, forgot you have to press the 'compressor overload release' button to start the compressor back up, but that results in the brakes not being able to be released as the main pressure drops, right hand needle went down to about 0.5Mpa when i noticed this... but i could also tell the brakes were not releasing by left hand gauge not going back to zero, Link to comment Share on other sites More sharing options...
stronzio Posted December 15, 2022 Share Posted December 15, 2022 (edited) You overcharged the brake pipe, don't drive with the train brake in "fill" position for prolonged periods of time, just use "running". FV4 is a "dumb" valve and if used improperly you could get weird things happening, like not being able to release the brakes as it happened here (Electronically controlled brakes are less prone to this). In worst cases IRL it would be a real pain because you may need to eliminate the overcharge on each single wagon by bleeding a special reservoir and it seems you can't do it in simrail atm Also, EU07 doesn't let current flow to the motors if you have some air in the brake cylinder (the first manometer on the left) EDIT: I think that Main reservoirs on the 07 are kinda bugged and show ludicrous pressures (> 10 bar) sometimes, but it should not really affect brake operation in game as far as I know Edited December 15, 2022 by stronzio Link to comment Share on other sites More sharing options...

And definitely if the direct brake is applied, too. Link to comment Share on other sites More sharing options...

And definitely if the direct brake is applied, too. It should depend on how much air you have into the cylinder, or at least that's what I learned in maszyna... The cutoff should be like 1/2 bars and there should also be a light on the desk that turns on (or off? Can't remember atm) when you have such block I'd have to check again in game for specifics but I'm quite sure that it also happens in simrail and it is also what happened to Sean here Link to comment Share on other sites More sharing options...
Gazz292 Posted December 15, 2022 Share Posted December 15, 2022 i think the traction lock operates when over 0.35Mpa is in the cylinders, i know i cheat as use the brakes in 'initial' handle position for a few seconds to slow down when my speed has crept slightly over the speed limit, rather than wind the power wheel back to zero, brake, then apply power again, Link to comment Share on other sites More sharing options...
stronzio Posted December 15, 2022 Share Posted December 15, 2022 Ok, so I managed to check briefly: any pressure of ~0,2MPa (2 bar) in the cylinder will cut out traction, but it seems that you can't unlock it again until you go back under 0,1. Maszyna has instead only one cut-off/cut-on value set at 0,2MPa. I'm not sure who's right but that's how it seem to work on those locomotives, basically Link to comment Share on other sites More sharing options...
