Steam & Excursion > SP 4449, anybody know where this one is?

SP 4449 under signal bridge
On Saturday, April 25, 1981, SP GS4 4449 went from Portland, OR, to Klamath Falls, OR, as part of its journey to Railfair 1981, the Grand Opening of the California State Railroad Museum in Sacramento, CA. SP 9338, an SD45T-2, traveled with it from Oakridge to Klamath Falls. I lost my notes from that trip, so I don't know where this photo was taken. It's somewhere between Oakridge and Klamath Falls.

I hope you like this post:

Yes. But, where is it?

Looks like Chemult OR.

If it is Chemult it can only be at the end of the siding south of town. Was there a signal bridge there? Not one now.

Thanks for posting the photo!

Agree W. Chemult. Signal bridge and a slight rise to one side of the track, maybe a curve and also road access. Compare with the photos of the signals in this webpage:

Amazing days, lots to see.

Thanks, those photos confirm the one time existence of a signal bridge at the south end of the siding, I'm fully on board with Chemult.

Hey folks thanks so much for the comments. As Colin Smith said, "this is most definitely the Chemult, OR signal bridge, now known under UP as 'CP VP502 Chemult'."

Nice pic!!

Is this picture from April 1981 also from Chemult?  Clearly a different signal bridge, but other features seem similar to the first picture.  From the pix on the redoveryellow.com site, I would guess  right at CP VP493 Yamsay.

Note the difference in the "draft intensity' of the two exhaust ( smoke) patterns;
comparing Photo 1 to Photo 2.

Photo 2 is with a virtually-closed throttle,  no draft at all from the cylinders.
Low draft always means low oxygen content, so even a little too much fuel 
and you've got too much freed-up carbon from the fire ---- but, adding more 
fuel simply makes for more unburnable, released carbon-chains.

What's needed is more OXYGEN, but there's no commensurate draft,
even with a wide-open 'blower-valve'.  The engineer, and the train + track grades
determine the draft rate into the firebox.  The fireman has little control over the 
available combustion-oxygen.

The  "blower valve"  is controlled in the cab by the fireman --- and is used when standing,
to keep flames and fumes out of the cab.  A full-open blower valve only approximates
about 3% to 5% of the draft from the pistons!

So, the effect you're seeing in both photos is a fireman, behind in 
his firing skills, so he's trying to play 'catch-up' --- by adding too much fuel
for the available oxygen...but, lack of air draft is working against him....
adding more fuel is making things worse-er, NOT better!

( For you 'valve-gear fans': in photo 2, note that the Walschaert valve gear is set
  with the radius-rod set very near the center-pivot of the Walschaert ( curved)
  "reverse-link).
