One set of controls turns on the steam, and the other turns on the water. There are four controls - two for each injector. EXHAUST steam injectors make use of the exhaust steam after you've run it through the cylinders, which is great as it wasn't going to do anything else anyway except chuff out the chimney - but of course this is only available once you're running at enough speed to actually have exhaust steam. This is steam that's available all the time but it will cost you boiler pressure. LIVE steam injectors use LIVE steam from the boiler. There are two kinds of Injector generally. If we start out with a boiler with plenty of boiling hot steam in it and we start injecting cold water, this condenses the steam and the boiler pressure is reduced - this is something to be very aware of as you proceed. In Train Simulator you never get that low (hopefully) and mechnical pumps aren't generally implemented. For info, at low boiler pressures when you have no steam to use, real steam engines have mechanical pumps to get water in, then they use injectors once steam is available. Injectors work by using Steam to force the water in - there's lots of info on the web about how they work. Water starts in the tank (or the tender) and we use something called an Injector to take water at normal atmospheric pressure and inject it in to the very high pressure environment inside the boiler.
It starts out as water and we need to convert it in to Steam. When you want to be clever, you can learn to turn off blowers and dampers and cut back your steam generation rate to allow the boiler to decrease in pressure as you come in to stations - nobody likes it when the safety valves kick off in a platform If the damper(s) are open then you will get a steam generation boost. Opening the Damper allows air to flow up from underneath the fire and through it - which is obviously a great benefit to feeding the fire. Starting this will give you a steam generation boost.ĭamper - Below the fire there is a grate, and below that there is a door (or two as in the case of the J94). As far as I can tell, there is no "cost" to you for stoking at any point so you can simple keep an eye on the fire mass percentage and stoke up if you need to at any point.īlower - When the blower is turned on it will force air up the chimney, this has the effect of drawing air up from the fire and feeding it. If the fire starts at 66% then I will usually go with running the fire from say 62% to 70%. I usually go with whatever the *starting* value is, so on the coal button it says "2.5 tons, 66%" - the 2.5 tons is how much is in the bunker / tender, the 66% is the size of your fire mass. How do you know what the ideal value is? The techie way is to look at the engine blueprint, it's in there. What does effective mean - it means steam generation.
The fire mass has an "ideal" value, at this ideal value the fire is most effective, if you are above or below it the fire becomes less effective. That's complex enough for us at the moment.
In Train Simulator it's a simple fire mass value, as you stoke it goes up and as you run the engine it goes down. In a real steam engine there is a fine art to loading on coal such as what size of coal lumps and where on the fire to put it. Stoking - this really is the simple act of adding more coal to the fire. As you get more proficient you'll learn to cut back your steam generation at the right times.Ĭreating a Fire - Train Simulator offers a number of controls here, these are: That's the key here, it's not simply a case of "as much as possible all the time", but let's get to that detail as we go, to start with if you can get it creating as much as possible then the worst that happens is you're continually blowing the safety valves and that's just noisy and a waste of steam. Your goal here is to create a fire that will provide the right amount of steam at the right time.
