Having (almost) finished refurbishing my deck I decided to play. Many of you are old enough to remember steam locomotive roundhouses. I am as interested in steam railway traction as I am in vintage electronics; many years ago, I was involved in a minor (very) way in the restoration of Bullied West Country Class Light Pacific 34105 “Swanage”. The “actual” locomotive below is a Hornby Stephenson’s Rocket which came out as a limited edition some 30+ years ago (I think 1979ish). It is live steam powered by butane gas which is held (mostly not held) in a small cylinder that is hidden in the faux water barrel. It was hard to get it hot enough to quit spewing gobs of oily water out of the stack however, once hot it could pull surprisingly well. There are videos on Utube showing examples pulling 3 or 4 carriages around outdoor 3 1/2″ gauge tracks in the UK. I filled the gap between the boiler tube and the sheet metal case with vermiculite (granular expanded mica) which helped things quite a bit. Anyway, here is the roundhouse:
The ‘scopes are going CW from the exit track, Tek 310, OS-8E/U, USM-32, Siemens 05, Telequipment S31, Triumph 830 (wobbulator/’scope), Tek 310A, Tek 310A. At the time, they were all fully operational.
