Robert, It seems most "sims" aren't really simulators at all, but simply layout design platforms. The steam sims I've seen also aren't simulators, but merely "skins" that are operated more like model trains, with very simple controls. Basically no difference between running a steam engine or a diesel. You don't need to know anything about how a steam locomotive operates--you just press the "go" button and you are on your way!

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? 'If you are too hasty and jump at conclusions, you may be wrong; better not know anything about it than know it wrong. Therefore, take time enough at first to learn it right; you will never regret it." --Charles McShane, "Classic American Locomotives," 1909

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

Disney Steam Locomotive Simulator

My good friend and collaborator, Preston Nirattisai (who did most of the drawings in my two books on the Disneyland Railroad), has been working over the past three years to develop a computer simulation of the operation of two of the Disney steam locomotives (demo below if you don't want to read all this). This isn't you're everyday steam simulator. It's designed to be as accurate as possible--every valve, lever and gauge works as it's intended. As Preston told me, he doesn't want this to be...

Looks very neat, but I doubt I have the discipline to learn how to really run a steam engine properly to enjoy it fully. I looked at some shots of the video, am I correct in noting that it will not be using the park perimeter as the scenery? Looked very nicely done either way. -Dave

I got the computer game Planet Coaster last year and there are two very nice steam train rides in it, with track that you can make any layout with, but no switches, just a loop layout with multiple stations possible. I also have Trainz 2012, a very good train sim to build routes with. K&L Trainz has a nice collection of payware steam.

Steve, I am surprised that YOU , of all people, would say that! You are most definitely not putting cold water in. Much to the contrary, the water is very hot. The loss of pressure is that you are using boiler pressure to operate the injector.

Seems it's available today! (when I checked earlier yesterday it wasn't yet) Not a bad deal, IMO. I need to get a faster computer! I'd love to see them someday offer more modern versions of the park scenery, but reading everything that went into doing even the original 1955/56 view makes it sound like it would get very intense very quickly from a design standpoint with all the drawings needing to be done. (and probably also need even a faster computer to keep up to run it!)...

Re: Disney Steam Locomotive Simulator

Yep, it has everything to do with the injector! The boiler pressure through the injector does not go back into the boiler. The boiler pressure turns the water into velocity, via the injector, and that is what forces the water past the check valve into the boiler. Now, almost all of the HEAT from the steam used to work the injector is retained in the feedwater and that is what DOES go back into the boiler! So let's go back to your incorrect temperature scenario. Remember that WATER is going...

Nice response and answer, Steve. An additional point about injectors is, the water volume can be throttled back, so that the injector (regardless of type & size) is only "dribbling" water into the boiler. During such use of the injector when the engine is working lightly, with sufficient fire in the firebox, the boiler pressure does NOT DROP. Now, concerning feedwater systems, first the Worthington "open type" ( type S and SA), there is NO "limiting feature" to prevent either the Fireman...

ARE YOU KIDDING ME BIG JIM?? Have you ever once even operated an injector? I don't have to believe in any myths. I have the EXPERIENCE! An open safety valve will release far more steam than my little injector, but I can probably lower the pressure faster using the injector than the safety will. WHY IS THAT?? Why do you think the check valve is placed so far forward on the boiler on most engines? Would the fact that injecting cooler water into the boiler farther away from the firebox will...

Right. I've had to use the big Nathan injector on both 4449 and 844 over the years during long down grade operations (remember, the Worthington Feedwater System should NOT be used when the throttle is closed down to just a drift), and when the Worthing System had a malfunction. Although sometimes a bit temperamental (bad water usually causes internal mineral build-up), the Elesco Exhaust Steam Injector on Challenger 3985 can be used at any time, even when sitting on display.

So, Steve, if your engine that has 380° water had a FWH and it was introducing that same 200° colder water, it wouldn't lose pressure? Maybe you need to use some common sense and have a long think about what you are saying instead of believing the myth that you so fervently want to hold on to! Now let's see, even at 380° - 200° equals 180°. I am not sticking any part of my body in that RELATIVELY COLD WATER!!! You really do need to go dig out your ICS books and re-educate yourself. Again Hot...

What’s your point? That the water injected into the boiler is heated by the injector? Conceded. That the steam used to inject the water is what causes the pressure to drop? Hogwash.

Oops, I forgot about trickling the water in--something I've had to do when I'm caught with my pants down, charging up-grade, water level dropping, and pressure dropping. Trickling water in will (hopefully) keep my water level at least steady, while not dropping the pressure precipitously.

Now, exactly how many steam locomotives have you fired, Big Jim? I'm guessing the answer to that is none, 'cause pretty much everything you wrote above is incorrect, or confused, or mistaken. I have never operated an engine with a feedwater heater, so unlike you, I won't presume to know precisely how they function beyond the basics. Hot Water can address those issues. I have, however, fired two engines with Sellers injectors, one for the last seven years (and one stationary boiler, with a...

"To prevent or stop the engine from blowing off, the supply of water (not steam--SMD) should be increased or the damper dropped." --Kirkman, Locomotive Fireman and Engineer's Handbook, 1906 "At ordinary working pressures, the difference between the temperature of the water in the boiler and the water of the entering feedwater is about 200 degrees F. When the engine is working the circulation is rapid and the temperatures soon equalize, but if the engine is standing, the temperatures equalize...

Steve, I haven't moved the goal post. Most of what you have said trying to defend your position merely defends mine. I also don't understand why you don't see how comparing the injector and feedwater heater is relevant. The relevence is that each is introducing water to the boiler at about the same temperature. Now, remembering that the Worthington system is an "open" system, the water supplied is near 212° +/-. Have you ever heard anyone say that water supplied by the FWH is "Cold"? Is your...

Big Jim, please stop moving the goal post, and defend, if you can, these statements: "The loss of pressure is that you are using boiler pressure to operate the injector."

I can tell you--and I know you already know this--that book learning can take you only so far. Before I put my hand on an injector or blower valve or atomizer, I had done the book reading. I knew all about the...

Hot water says........Since you have never actually worked on, nor with, a steam locomotive, there is obviously no sense in discussing boiler pressures and injectors with you any more. Really?

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?

Just getting into this thread. The simulator looks pretty interesting. This engine looks just slightly simpler than the one I used to operate so I will probably look into this program. And yes, from personal experience, using the injector to add water to the boiler will lower the pressure.

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

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...
