Steam & Excursion > Bill Gwinn Photos (5) - NYC

(Bill Gwinn Photos (4) can be see in Nostalgia and History.) Here are two more photos taken with Bill's box cameras.
1.) NYC 3136 (A 4-8-2 Mohawk/The NYC name for a Mountain) is in the NYC Collinwood facility in Cleveland, Ohio on September 6, 1953.
2,) NYC 5446 is in Collinwood Yard in Cleveland on September 6, 1953.

Thank you for more pics of "my" railroad, the New York Central.

Nice stuff.  Dumb question. How did Mohawk get that name on NYC?

Maybe from the Mohawk Indian Tribe? Isn't there also a Mohawk River?

Mountain would not be a good name for an engine on a railroad advertised
as The Water Level Route.

Named after Rivers....
Like in "Hudson",  "Niagara", "Mohawk", erc.

The NYC and West Shore mains followed the Mohawk River west from the Hudson Valley in New York State.

Yes, named for rivers, and here is a Niagara from my Vollrath collection.

Cool pics, thanks for posting.

What do you call those drivers on the 3100 series 4-8-2?  Are they considered bok pox (SP?) or disc.  Any more pictures of those L-4's.  Really like the "I mean business" look of those engines.
Greg

Scullin Disc.

Agreed..

Apparently, after several years of service the Scullins developed cracks
in their castings --- Boxpoks were used to replace the Scullins.
Interestingly, 'Boxpok' was a trade name 'contraction'  from 'Box Spoke'.

If you examine closely the driver-center casting there are several ( closed)
rectangular 'boxes' that form hollow 'spokes' around the wheel circumference ...
.the whole wheel is a lighter arrangement than the old 'wagon wheel' spokes
of earlier driver centers.  The Boxpok design also gave a stronger, more uniform
support ( around the whole wheel-center) to the warmed-up, & expanded driver-tires
as they shrank, when cooled, onto the driver centers.

So, I use 'BoxSpoke' when talking about those driver centers.

W.

( The driver tire ring-like burners that you see warming up the steel tires,
   are only used to 'warm' the tires --- 90% of the expansion is achieved 
   under 325F ... the manufactured tires are hardened, and heat-treated
   at the factory, so you don't want to loose that heat-treatment by over-heating
   at the time of application of the tire to the wheel center.

   That also corresponds to the caution of applying driver brakes to wheels
    fitted with shrunk-on driver tires.  Just a few revolutions of friction from
     the driver brakes can heat-up, and possibly loosen the driver tires.

    Engines moved over the MainLines, without cars (for braking purposes) ,
     are limited to 25mph, or slower ( fears of the loose-tire syndrome).
      
     With even just 1 or 2 trailing cars, you can run the 'train' at track speed,
       by using the cars' brakes for stopping..).

Thanks.  I sorta knew what I was talking about but didn't remember the correct wording.  Anyway I like those types of driving wheels.  Weren't there some that were solid as well, or nearly solid on the NYC?
Streamlined Hudson, maybe?
Greg

Yes,
the Scullin Steel driver centers were nearly 'solid', disk-like,
in appearance ( with only a few 'port holes'), and many were painted white.  

Those were the ones that seemed to be vulnerable
to developing cracks, after a couple of years of service.

I don't know of any locos, on display today, that have Scullin 'disk'
driver centers.

W.

Here is a NY Central Hudson with the disc drivers.

Thanks NYC man.  Those are really nice looking drivers.  I thought they were on those hudsons.  I got to see a bit of NYC steam circa 55-57, in the Cincinnati area mainly. Dad has a movie clip of me getting a cab ride in an 0-6-0 at Riverside.  I was about 4-5 at the time. I do remember doubleheading from Riverside to Sunman, IN as we chased many of those.  Dad rode the Riley to Chicago with Hudsons before they were gone. Loved those big tenders on the NYC power.

Concerning those Scullin Drivers, I remember being on the New York Central during the winter of 1963/1964 with the EMD GP35-DD35-DD35-GP35 Demonstrator set. Every chance I got, I talked with the "old head" Engineers that would have been Engineers and/or Firemen back in the steam days. I remember more than one of the men, expounding on the performance and ride qualities of the Hudsons, especially at high speeds. One man, who was a promoted Engineer on steam, but preferred to exercise his seniority as a Fireman on passenger assignments, said that those damned "disc drive wheels" would "scream & howl" even over the exhaust sound at speeds over 75 MPH! Lots of men complained but, nothing was ever done to "fix them". 

Interesting!....
You think that was "wind-noise" ( from those few holes),  Jack?
Act almost like a flute?

At 70-MPH, for a Hudson, that's about 300 RPMs

Most likely, i.e. air pressure/wind circulating in and out of those holes.
