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
