Monson 3 and 4's Throttles
« on: July 03, 2024, 01:44:04 PM »
Reading through older newsletters (specifically for the 2-foot Musings by Ellis Walker) he brings up Monson 3 and 4's throttles and that when they arrived to Edaville they had quote "simple screw-type steam heat radiator valves, in place of conventional throttles." From the March/April 2015 edition of the newsletter. He also mentions lack of proof for this being the case.

I guess my question boils down to if this was *likely* to have been the case. Were other Vulcan engines built with this arrangement, or was this just rumor rooted in pure myth? Could it have also been a temporary addition when the engines were first restored to run at Edaville? Is there any evidence to this being the case on either engine?

Dante, the very last correspondence I had with Ellis involved this subject. I am trusting to recollection only as I write this, but I thought his question had to do with piping from the steam dome of one of the locomotives. I sent him a photo of (I believe Monson no. 3's) steam dome, which showed proper (code) piping arrangement. I cannot imagine a radiator valve being substituted for a throttle, passing muster with an inspector. Would such a radiator valve work? Perhaps...
Wanted: Copies of correspondence and photographs from "first generation narrow gage railfans" such as Linwood Moody, Dick Andrews, Lawrence Brown, Ellis Atwood, H.T. Crittenden and others. Interested in all two foot (U.S.) rail operations, common carrier, industrial/mill and park/museum.
