The operative working phrase witrh these Steam Locos is “fast passenger.” You can bet if the speed limits allow it Steve Lee and Ross Rowland will let them roll at track speed. Having chased the 3985 and 844 here in Kansas. They Will roll at track speed![tup][tup][:D]
The factor I’ve seen was 1.1, as in approx. max. speed (in MPH) = 1.1 x driver diam. (in inches). So, for 72" drivers, it wold be 79 or 80 MPH, which seems about right.
I’m pretty sure 614 was for fast freight, not passenger, esp. on C&O - a coal road. Plus, I understand that the T-614 was rebuilt for freight use, not passenger. Modern ten-coupled passenger power was rare, aside from maybe UP’s 4-10-2’s and 4-12-2’s. More common was 8-coupled, like Northerns (4-8-4) and Mountains (4-8-2). Both UP & AT&SF used 4-8-4’s as their fast passenger power, even though they too had larger (ATSF also had 2-10-4’s).
The C&O Greenbriers (4-8-4s, but never call them “Northerns”!) were in fact built as passenger locomotives.
C&O used its 2-10-4s (the 3000 series) and 2-12-6s (the 1600 series [;)]) for coal trains, though the latter probably could have handled passenger as well without problems.
"Open mouth, insert foot . . . ", or, as Roseanne Rosannadanna (the late Gilda Radner) used to say on Saturday Night Live: “Nevermind.” [:I]
Well, at least my reasoning was pretty close. And thanks for pointing that out - I learned something new: 614 is a 4-8-4, not a 2-10-4 - for some reason, I really thought it was. Oh well. And nice to know there’s yet another 4-8-4 in the land.
If you’ve never stood alongside a mainline facing an oncoming train doing 60, 70, or even 80, you can’t realize the sensation. Been there, done that. It’s imposing, even frightening.
CSX runs through the Utica station at track speed most of the time. For intermodals, that’s 60. You step back, even if you’ve already stepped back.
Seeing a big Northern (or Greenbrier, or FEF, or GS) bearing down on you at speed is certainly an intimidating experience.
