BIG JIM,

Question; how do explain putting on the injector (say a Nathan 4000), quickly throttling back the water so that only a VERY small amount of water is "dribbled" into the boiler. The boiler steam pressure does NOT drop, because there is very minimal water going into the boiler. Why doesn't the boiler pressure drop, what with all that steam being used through the injector?

I believe that the Nathan 4000 is a double jet injector or "Inspirator". This type of injector can supply water at a higher temperature (above 212°) than an ordinary injector. It has the ability to supply water, not only with a water supply valve, but also with a steam regulation valve. In this case with a low amount of water being desired, the amount of steam needed would be proportional.

Merry Christmas, Steve

Nope.

Merry Christmas to you.

How about a Sellers 6.5? An injector from the folks that basically brought the injector to the railroads in the 1860s? It's not an inspirator. It's an injector. Old-school.

Please please PLEASE explain how I can open the water valve, pull the steam valve FULL, COMPLETELY, ALL-THE-WAY OPEN, allowing dry steam from the top of the steam dome into the injector and from there into the boiler, and then, before hardly any water gets injected, turn the water valve closed until just a very slight trickle is going into the boiler, but the steam valve is still WIDE OPEN. And yet...

...The boiler pressure does not do down, in complete contradiction to your unsupported, completely preposterous and unfounded theory.

Next you'll tell me that opening the blowdown will cause the pressure to drop significantly because of all the heated water that's being released.

Big Jim?

I'm waiting. It's been four days. Either for an explanation, or an apology.

I would never claim to be an expert in diesel operation; why do you claim to an expert in steam?

Steve,
I said "Merry Christmas" to you. 
Now, since you insist on being so insolent and immature in thinking that I must explain or report back to you in a certain amount of time as if I have nothing better to do this Christmas season, I am only going to ask that you take your own above advice. And, I'll leave it at that. 

HAPPY NEW YEAR Steve

And I said "Merry Christmas" to you.  I didn't know "Merry Christmas" meant "Shut up." Report back when you're ready. Or can.

And of course, Happy New Year to you and yours. And you know I mean that sincerely.

Okay, now back to that Disney Steam Locomotive Simulator................

HAPPY NEW YEAR!

Since he was "backed into a corner", and obviously was NOT about to admit he was/is in error, I wouldn't expect any different sort of come-back.

And of course, Happy New Year to you and yours. And you know I mean that sincerely.

Here's the first review I've seen from someone not necessarily experienced with steam locomotive operation. Alex gives some good third-party feedback.
