Thread: P42 Speedometer

  1. #1

    Default P42 Speedometer

    Does the real p42 speedometer stop at 80 mph? Seeing as how amtraks go faster than that, I was wondering if 3dts made a mistake with the display.

    Usually max track speeds on the rails usually don't exceed 80 mph unless the track itself can handle high speeds which I think is set at 90 and above. Most locomotives nowadays use displays so of course it can exceed 80 unless governed.

    Tyman,

    If I'm not wrong, it's not a mistake... Run8 Team probably decided, so far, to use in the P42 the same MFD screen of ES44DC. I guess (that's just my humble thought) that create a new and prototypical SIS (MFD in Run 8) would take a lot of programming and of course would last months, and right now isn't worth in face of other priority stuffs on the works.

    ES44DC's max speed is 75MPH, and its speedometer marks up to 80 MPH, as per the real engine manual of operation. I don't have (yet) the P42 manual, so I cannot say what its speedometer markers show (anyway the digital display shows the current speed).

    What I know is that max allowed speed for passengers trains in Mojave Sub (either BNSF and UP) is 70 MPH.

    Needles Sub is 167.8 miles long. The max allowed speed for passengers' trains are in total (more or less):
    Main 1 (Westwards): 90 MPH, 91 miles; 79 MPH, 76 miles.
    Main 2 (Eastwards): 90 MPH, 64 miles; 79 MPH, 104 miles.
    Main 3: only 79 MPH, 10 miles.

    Cheers,
    Doc.

    The actual P42DC speedometer goes up to 120mph.

    A little fuzzy, but it does indeed go up to 120.
