Thread: Definition of Empties

  1. #1

    Default Definition of Empties

    Z-ALTNBY is shown on the MFD to have about 1/2 loads and 1/2 empties. However, visually, all the well
    cars have double stack containers, and all the pigs have trailers.

    So how do we define an "empty" for the sake of max intermodal operating speeds?

    Clearly, a train of empty
    well cars qualifies as a bare table, i.e. an empty string, thus max speed is thereby limited to 55 mph.

    However, if a train has a mixture of empty and loaded containers or trailers, can this train still be run at the
    max authorized 70 mph?

    In other words: Can I run Z-ALTNBY at 70 or 55?

    My understanding is the loads/empties doesn't matter for purposes of IM speeds, as long as the trucks are modern ones, as all Run8 cars are,at least, that is what the real RR'ers on the DAMS server said in interpreting the timetable rules

    I have been told that a professional on the BNSF says I am wrong. My understanding came from discussing the issue on DAMS with some real world RRer's, at least one of whom worked on another BNSF sub.
