While you’re at it – there was also the Street underfeed stoker that was rather unsuccessfully put on the first PRR K4s – souring PRR on subsequent stoker use to the point they left stokers off the K5s as built, one of the dumbest of the dumb things a railroad did in that era…
Apart from the short-lived “G” Class Garretts amongst whose faults were an over complicated mechanical stoker, the NZR relied on firemen and shovel power, so due to Ed and others, I’ve learnt a lot, and have come to the conclusion that the “G” Class mechanical stokers must have been real doozies!
[^o)] Hmmm, 900 and something views and no one’s taking up Eds offer.
Ok, so what were the “Detroit”, “Manitowoc”, “Windsor” and “Pere Marquette 10”?
Judgeing from the position of the equipment, especially where those pipes are pointing, and the fact that it is winter, my best guess is those are switch heaters!
I think I’m supposed to ask a question now right?
How about what do “Stampede”, “Stevens”, and “Snoqualmie” have to do with railroads?
P.S. I’m not 100% sure if I’m following the rules correctly here, so if I’m not please let me know!
What, and when, was the first fixed rail crossing of the Mississippi River?
(Isn’t that silver box some kind of power derail, or perhaps an ‘occupancy sensor’ or axle counting device? It isn’t placed where it would do any good as a switch heater, it has a head reminiscent of a typical motor drive, and I see no tanks or lines for the fuel necessary in such a location for a heater. Note the large number of tie bars to the movable points, indicating either heavy loads or preservation of high-speed geometry…)
I considered the previously posted image being a derail, but it seems to me that they are not connected to the points, to me it looks like the switch rod heads off to the left out of the photo…
Occupancy detector seems possible… I don’t really know how they work…
I honestly have no idea what it is, these where just the reasons I didn’t say switch machine (that was actually my first idea!). I honestly can’t wait till the poster of that question responds! I don’t really care if I’m right, I just REALLY want to know the answer!
I checked out that link on switch heaters, very cool! They would make a nice detail for the more modern railroads, I wonder if anyone has done one on a model railroad?
Of course, this also means Isaac gets the next question… oh wait, he did. Carry on!
That thing would make a nifty set of detail castings for modelers. One piece for the box, one for the ‘manifold’, two for the directional heads… clean out a crib and glue it on down; doesn’t even seem to require detail painting.
Sorry for the late response, I got involved with a project and never got back to this. 1936 is indeed the correct build date for the first UP Challenger. If anyone is interested in more info on Camelback locos, this Wikipedia artical is where I got my information from. https://en.wikipedia.org/wiki/Camelback_locomotive This should be a fun and interesting thread if we can keep it going. I really like trivia, that’s why Jeopardy is one of my favourite tv shows.
I was going for now, and I didn’t count Caltrain or other mainly transit railroads. My mistake. I guess I was aiming at freight-carrying railroads, but that’s not what I said.
