Jimmy Lisle!!
I assume you run between Roanoke & Shenandoah?-- do you work V90/V91 regularly?? Is it a shorthaul or thru freight?? Bet it's a pretty run; particularly during the fall of the year.? My wife does home health care and has a patient in Vesuvius; along South River Rd.? We came out @ Beuna Vista.
My e-mail address is DaleD1acont at aol.com if you want to talk "shop" sometimes.? Have a safe trip and keep 'em on the rails.

Hey Guys,
Y'all certainly have an active and most interesting website.? I'm an engineer on
CSX (old A-Line) running between Acca?& Florence, SC.? Our ranks of SD40s in the
"8000" series are really thinning out.? My younger?brothers who catch them cuss
'em like a hound dog but they know little about what a significant unit they're
aboard.
Anyway, I know it's not news to?you guys but I noticed a bunch of apparently
rebuilt NS SD40s pushing up the old PRR grade west of Gallitzin, PA.? I live in
Waynesboro, VA?and was wondering if there was anywhere else that NS uses SD40s
in significant numbers to make the effort to photograph.? Got some vacation time
in Oct. that I'd like to see some SD40s in action.
Thank you very much.

Dale,
I had a dream trip just the other day. Went up to Shenandoah on the V90 with
three, yes three, I said count 'em THREE SD40-2's. Then caught the V91 back the
next day with the same units. What a treat it was to have a train where the
units actually responded to the throttle!
Keep an eye out on the "Valley" and around Waynesboro for the V90/V91. It
usually has a mixed bag of odd ball units, especially GP38-2's, but, SD40's
have been used on this train quite frequently.

Superheaters and Throttle LinkageOne thing not covered in this discussion so far
is the effect on the throttle linkage of boiler longitudinal expansion and
contraction because of temperature changes for the situation where the throttle
in the cab would be latched in the "off" position, so I'll post some comments
for the experts to take pot shots at.
Differential changes in length between the throttle rods and the boiler as the
latter heats up or cools down while the throttle is latched in the "off"
position in the cab could c
ause the throttle valve to be either pressed harder
on its seat, or to be raised slightly from its seat. In the latter case, steam
could seep into the cylinders causing an unattended locomotive to "walk away."
There are many tales about instances where this occurred. This possibility is
one reason that heavy chains were placed on the rails fore and aft of one or
more driving wheels on parked steam locomotives in shops and servicing areas.
Throttle rods passing through the boiler probably were the least affected by
boiler expansion and contaction inasmuch as the throttle rods should experience
essentially the same temperature changes as the boiler and have essentially the
same expansion and contraction.
It seems to me that the throttle rods on the Ms and Ws that went from the cab
over top of the boiler to the steam dome would have been the most affected by
boiler length changes because they were exposed only to ambient temperatures.
Front end throttle linkages on the exterior of a boiler had a compensating lever
located about mid length of the boiler. This lever was pivoted at its center, so
any expansion or contraction of the boiler length would simply change the angle
of the lever slightly without changing the force on the throttle seat.

Subject: Re: Superheaters and Throttle Linkage
Bill -
The As, E2s, E3s, Js (including at least one of the J 4-4-2s) K 4-8-2s,
selected Ms and M-1s, all M-2s, all S-1 and S-1a 0-8-0s, selected W-2s, all Ys
except the Y-1s, and all Zs were equipped with superheaters.
Suggest you consult the revised edition of Bud Jeffries' GIANT OF STEAM; Bud
has the numbers of the Ms and Ws that had superheaters. W-2 778 pictured in
August Thieme's book has a superheater.
The presence of a linkage to the front end only denotes the presence of a
front-end throttle; most of those used by the N&W were American Multiples whi
ch
were located in the superheater header. Some Y-5s used a Bradford front-end
throttle which was in a dome ahead of the stack.
All the others had the throttle located in the steam dome; the K-1s used an
external throttle rod going from the cab to the side of the steam dome. The
others had the throttle rod going into the boiler through a packing gland in the
back ot the boiler head, and up to the dome. Ms and Ws had the throttle rod
going into the back of the steam dome above the boiler top from the linkage
inside the cab, because the engineer didn't sit behind the rear of the firebox;
he sat beside it and the throttle was up on the side/top of the boiler.
Engines with superheaters did NOT usually have a front-end throttle, but
engines with front-end throttles had superheaters.

Subject: Superheaters and Throttle Linkage
I was looking at the picture of Y-3a 2077 on the August page of the NWHS
2009 Classic Calendar and noticed that it didn't have the throttle linkage on
the engineer's side to the smokebox like the Y-6's and and A's. After doing a
little bit of research I discovered that locomotives with a superheater usually
had a front-end throttle which I hadn't heard of previously. The linkage on
the Y-6's and A's apparently go to such a front-end throttle. I guess this
means that the Y-3's, or at least this one, were not superheated. I think that
the actual throttle valve in a non front-end throttle situation was located in
one of the domes; in the case of the Y-3a, I would guess that it would be the
2nd dome back from the stack. The dome just behind the stack appears to be a
sand dome. My questions: how did the linkage get from the cab to the dome that
had the throttle - nothing is apparent in the photo. Also, which N&W engines
were superheated? Were the J's? Were the K2a'
s? Were the K1's.?
Thanks,
Bill Mason
