Uh, not exactly . . . .a small economic event
called the Depression intervened.  Those plans
were made in '29.

Actually, they could have, just as the ERIE's
2-8-8-8-2's spent their lives pushing up hills.

I believe that 3985 is "limited" to 79 mph.  As
long as anybody's looking.  The Challenger class
was a speed-demon class, and generally misused by
almost all the railroads that had them.  The D&H
did run them fast once they got up the hills.

Those are good examples.  And yes, they did run
fast enough to 'not bog down' the rest of the
railroad.  The UP painted some of the Challengers
in the two-tone gray in part because they were
used on passenger trains.

It's true, Paul, that many articulateds were
slow-speed machines, but that was because, as Tom
B infers, they had small drivers, which do limit
practical speeds, and also because many of them
were compound machines.  That doesn't
>>automatically<< make them slow, but it
contributes to it.

Certainly, the DL&W could have used articulateds,
either for pushing up the hills out of Scranton,
or for high-speed running in the flats west of
Binghamton . . . .or both.  Probably not with the
same machines, but both.  But, they had pretty
good power as it was, with the 4-8-2s, and the
Poconos, so they had no need . . .
