MU consist logic

[NW Mailing List]

Sounds like the time when I was assigned to ride the Roadrunner (piggyback between Brooklyn Yard at East St. Louis and Landers at Chicago) and we came out of Brooklyn with two F7s and about thirty pigs.  Boody Hill south of Decrater  was conquered at 27 MPH (the Roadrunner was allowed 65).

Great story, Harry. Thanks!

  Carl:
  Most (but not all) engine assignments were  made
  at a service facility.  Basically, what came in for
  service was dispatched as is, but engines bad ordered or
  due maintenenace would be cut out and replaced
  by other units. The outbound engine crews didn't
  get to choose. 

  But there was more to it than just comfort.  In the
  mid-70s, there was a comparison made between
  a computerized train simulation and an actual run.
  The experiment was made on the Fostoria District--
  that part of the Lake Erie Division between Bellevue
  and Fort Wayne.  There very few grades, a sixty-mile
  tangent with two correcting curves so slight they were
  visually hard to detect, and a maximum authorized
  speed of 60 MPH.

  One of the first trains tested was TC-3, a run-through to
  the Union Pacific.  In rank of symbol superiority, TC-3 came
  right behind the all-TOFC trains, AP-1 and AP-2.

  On test day, the service track assigned three ex-Wabash
  3400s -- GP7s and GP9s.  So while the Terminal Supt.
  would go to "8" on the Richter scale if TC-3 was delayed,
  the symbol left Bellevue on time with jam-up tonnage.
  Crossing the Fostoria District, the train balanced at
  22 MPH -- meaning  in Run 8,  on the flat-as-a-pancake
  profile, 22 MPH was all it could "git".       Harry Bundy
