    Incidentally, does anyone know exactly what the "0 MI" in the top left of the display is telling us? It appears to be related to distance travelled, but it increments much too fast for it to be straight miles. Any offers?

    Why do you have DP Remote brake control disabled on all locos?

    I wondered that also.
    That's how they Spawn and I cant seem to find a way to change it.
    I assume it has to do with Distributed Power which is handled by Banking Comm?

    I was assuming it was miles but I haven't paid close enough attention to confirm that.
    It does increment But at what rate?
    Might be associated with the line of sight problem in calculating distances.

    I think Matt said on stream on Sunday that it is difficult to implement the DPU remote into the MFD so that's why it will say disabled. The easiest way to simulate DPU in the sim is though the banking comms button on the radio.

    How do you get these to work properly? The pipe only blows up at 89 which will not release the brakes to move. I have it cut in, cascader on ats on but it is not correct pressure. How do you get the brakes to full release?

    Edit: Now I have a PCS open light which now prevents me creating air, why aren't the brakes releasing?

    Actually the automatic brake already released when the rear pressure reach at least 75 psi, you can start moving. Don't apply too much power.

    The brakes on the wagons are stuck on, as soon as I start moving it will stretch the formation but it will not move. I can't even create now as I have a PCS warning light. Is this for the cascader and how does this system work?

    EDIT: I have it set to...
    Brakes lead: cut in
    CSS (Cascader Service System as I am told but don't know what it does): cut in
    ATS (???, Automatic Train Control?): cut in
    Reservoir: 90
    Train pipe: 89
    Dash switches: on on on
    The generator current showing it is under load but it only stretches the couplings and does not move the full rake.

    That's at the front, in your lead loco. What's the reading at the rear (small box, left side of the MFD under the big brake pipe readout)? That's the one you have to get up to at least 70 psi (80 is better) -- but it takes around ten minutes. Filling a mile-and-a-half-long pipe with air takes a while.

    (Note: the physics model is not quite accurate. IRL with a top-and-tail consist the pipe would be filling from the locos at both ends towards the middle, and your key gauge is the airflow meter. But that hasn't (yet) been implemented. OTOH, IRL the time to charge brakes is more like 30 minutes)

    This could also be your problem. Rear Lead Unit reverser stuck.
    https://forums.dovetailgames.com/threads/sd70ace-up-banking-comm-reversers-unsynchronized.49216/

    There is a lot to learn to get these Locos moving.
    Take your time and be patient.
    Following procedures closely will help.
    There is a lot of info about brakes on the forums if you search.

    Make sure your setting up the brakes according to procedure. (Like Pictures)
    Front Lead Unit
    Screen: Lead - Cut In
    CSS mode Cut Out (like pictures)
    ATC mode Cut Out (like pictures)

    Then if still not working turn Banking Comm off and on to reset and move reverser back and forward to reset.

    I'm not sure how you popped the Pneumatic Control Switch, but it has dumped the brake pipe and you have to recharge all over again.

    Pneumatic control switch? As in the electro-pneumatic control system a lot of older UK locomotives have where you can hear the air hissing out of the system when you push the throttle back? I was under the understanding that most US built locos had completely electronic control equipment which is why EMD locos don't seem to mind when you shut the throttle completely off as it, whereas with EE & some other builders you need to wait for the RPM to drop before putting the throttle in to off. What are the CCS and ATS for and how do you cut them out?

    The PCS (Pneumatic Control Switch) is a safety device which opens the air system if airflow exceeds a certain rate; the assumption is that you have a separation or hose rupture and the train needs to stop Right Now. However, it's possible to trip it accidentally; in TSW, which abstracts the hookup of air hoses when coupling, one can often have this happen when connecting a cut. However, in previous routes we didn't have to deal with 10-minute recharge times.

    You can't cut them in, they are presets because they don't work in game.

    ATC: Automatic Train Control.
    CSS: Cab Safety System.

    I think the CCS on the top of the box should be CSS? :)

    I do have a question about DPU, sorry if is slight off topic, and maybe a bit stupid.

    Should the rear/mid locomotive's compressor help charge the train brake? Or is that unfarovable as a rear and front PU would create a situation where the brakes are released from the ends to the center? (which I guess could be solved using the indipendent on both ends)

    Yes, it should and in RL does. However, TSW does not currently model it (they have temporized somewhat by speeding up the brake charging time to 10 minutes instead of a realistic 30, but it is still modeled as going from the front back).

    it's just the opposite it's going slower than it should. it should be 3:30 in a 107 wagon train. Will explain this more next week

    Maybe they could create screen like timetable for brake status along train.
    #001 BP-90 EQ-90 SR- 89 BC-00
    #002 BP-89 EQ-89 SR- 89 BC-00
    ...
    #100 BP-60 EQ-60 SR- 59 BC-63
    Player can scroll down to see how brakes release along trainlength
    Brake Pipe (BP) pressure rises
    Service Reserviors (SR) are filed
    Brake Cylinders (BC) are droping - releasing brakes
    You can also see which part of train have no brakes (SR 64-74) which part have limited brake ability (SR 75-85) and which is strong enought to create efective brake force (SR 86-90).
    If SR 90 Min. reduction of BP to 84 cause about 10PSI on BC,so if your SR are not charged enought and reeds for example 75 BC is just 2-3 what means almost nothing for your heavy train.
    TrainSim-Matt will such brake screen be hard to implement and used it in brake turorial for less experieced playes to gain knowledge ingame or it is not worth of devpower?

    Train Simulator 2022 has something like what your talking about.
    I set the brake on the second car. First two are the engines.
    You can also uncouple the cars. I think the little wheel turns red when there is a problem?

    No, TS don't simulate brake like TSW simugraph do. That is just handbrake setup, in TSW you can set it also...
    I remenber that MSTS have BP pressure values in wehicles in console.
