    So I ended up speeding, and the dynamic brake and auto brake weren't handle it as the speed was going to rapid for them to slow it down fast enough.
    Popped the emergency brake which brought me to a standstill. I waited till my EQ and BP were both 90, but it seems the brakes on the wagons are still on and the rear pressure is listed as 0.
    How do I recover from this properly?

    Wait. The BP reading you see is at the lead loco, but there is a mile or more of rubber hose to pump up. The Rear reading is the one to watch.

    Just a tip for next time, dynamics are effective up to 30mph. Dynamics should be enough to maintain your speed going downhill. If you ever need to apply automatic brake, every time you apply and increase brake force, you have to bail off independent so you can still have dynamics working. If you don't the automatic brake takes over because it's stronger and dynamics are no longer applied.

    Yeah, I can normally do it by following that procedure. I had a concentration lapse due to a phonecall, and when I looked back I was at 60MPH, well in the red lol. So slapped the Emergency brake.

    A couple of little tricks, not great driving practices, but if you want to see things for yourself they are useful and interesting to observe.

    If you're headed up hill, put the independant brake on, release the auto brake and then go watch the back of the train. At some point, it'll start rolling backwards until all the slack of the train is let out. The moment it starts moving backwards you're running free - but don't move yet, give those brakes some time to charge and definitely don't "snap" the couplers by moving until those cars have settled at any rate. Of course this requires that the stop compressed the couplers in the first place, if everything was loose nothing will really change but depending on the cars you may see the brake shoes move away from the wheels.

    If you're going down hill, release the train brake and basically "hang" on the rear of the train - as car brakes release, the loco will edge forward a coupler slack length and eventually you'll get the rear of the train released and start rolling. If the cars stopped with the couplers at their furthest apart, hold the independant brake on and then as the car brakes release you'll see them roll a small amount into the one in front and you can watch this rippling down the train.

    Bad practices because you really need to wait for that brake pipe to full charge again before you set off... but an interesting experiment to try once and see for yourself. :)

    Matt.

  7. Your brake pipe is 89 try to movie it.

    Unsure if the EOT is showing BP or not. Cannot be zero if the loco is 89. If charging might be 70? Not 0.

    After a few minutes, maybe 5, should have plenty of air to move.
     
  8. Oh if you pulled a lever you might have to put the lever back.

  9. I went on to Cajon Pass and released the brake and this what happened. Withing about 2 minutews it started rolling. Or less.

    Then I applied an emergency and waited 20 seconds then released.

    Then it started moving again about 2-3 minutes later. For exact time check the time imprint on screenshots.

    One more reply to post the post emergency brake release screenshot.

    I was on Sherman Hill, but should be the same. I waited stationary for 15 minutes and the Rear value on the screen still read 0. But I was eventually able to move and complete the service. The rear value never went back up from 0 though, so I don't know if that's a bug or not.

  11. Mt EOT has pressure so not sure what the problem with yours is.

    What platform are you on? PC/PS/Xbox?
    What route?
    And what locomotive exactly. (UP/BNSF/NS etc?)

  12. Please tell me which service? Time and service timetable number?

    What platform are you on?
     
  13. Matt, unsure if you want to bother with this (bit technical) but when reverser is in neutral or out a train movement alarm will occur and immediately dispense emergency brake application.
    Quite a bit of effort and time (and for no reward I'm guessing) to replicate the various safety systems in modern American locomotives.

    PC, Sherman Hill, UP SD70ACe.
    Can't check which service right now, but it was an Ethanol train leaving at around 11am, heading south. One of the longer ones.

  15. Ok, will have a look today sometime for you. Glad you could complete it though. Sometimes you will spend 30 minutes or an hour on a train (and that is nothing for real life drivers-you get out a book or play cards ie Trumps Yuca I forgot the popular game amongst railroaders) sitting at a siding waiting for a meet or a line closure......
    Enjoy!!
