Would have to agree with Geoff here. Neither compressed air or steam is
completely danger free.
One word: shrapnel. There have been a rash of SCUBA tanks that were
manufactured from a specific alloy that have been known to explode with some
horrific results. The tanks have all been properly vi
I have seen two "half breed" (that's what the owner called them) engines in
my time. They were both steam engines that were converted to burn diesel (or
maybe gas. can't remember for sure). I know that one of them was a Corliss
engine, the other I don't recall. Both of them were large mill engin
Steve,
Your explanation of the compounding system was spot on. You mentioned
the loss of volume due to cooling between primary exhaust and secondary
intake. Early on, the exhaust steam was send straight to the low-pressure
cylinders, but that was apparently problematic. This was solved by r

May I recommend to you the B&O "Grasshopper"? It was a very early
engine, using a twin walking beam design. Aster built a nice little live steam
model of it
Hey Trot,
Thanks for the heads up on the article. Interesting to say the least.
Especially since I'm currently getting around 12 MPG city, 16 MPG hwy.
I've seen compressed air (SCUBA tank) used for an underwater scooter once. It
too was nothing more than a steam engine. It never gained popula

Re your comments on air explosions, not so TrotFox, me boy, an

Vance,
There are now a few models of airplane and at least two types of car that
do the same. From what I've seen they work really well. Can't comment on
noise or efficiency because I'm only going on the hobby shop owner's

I think that you should contact the National Railway Historical Society
and let them know about these plans and drawings. I am sure that they would
most likely be interested in them. You may even have a local chapter in your
area.
It would surely be a shame if they wound up i
While brousing through a well worn copy of N.K. Harris' Model Statonary

Regarding SaltyChief's statement: "Take a look at the old three cylinder
marine engines. They had three different sized cylinders with the exhaust
from one cylinder feeding the next
cylinder. To use the exhaust from one set of cylinders to power another set
they have to be different sizes."
There was (or still is) a compressed air driven loco in Disneyland--my
company, Ingersoll Rand provided the air compressor. I don't recall whether
it was diesel or gas powered. Incidentally, it only travelled a short

After many months of searching I have finally found a copy of N.K.

everyone tells me it will be.

When it's back to it's original configuration it will be two mainlines of 45mm
gauge. They will each have a passing siding of about 100 feet in length (the
overall length of each loop is close to 500 feet) with only one cross over
where you enter the inside mainline from the yard.
