The blower is used when the locomotive is at a standstill as it draws the fire. When the locomotive is running it isn’t required as the exhaust gases passing up through the chimney is enough to draw the fire.
Hi, I am sorry to bother you again, I have two more questions about the train operation , 1. As the train starts to run , should I leave the water bypass valve open or closed ? 2. How to empty the water left in the boiler after finishing each running ? Thank you Best regards @@neilbottle6662
@zhengyangwang9713 That's ok, we all have to start somewhere so I don't mind the questions. The water bypass generally depends on the amount of water in the sight gauge glass. If it's full up to the top nut open the bypass, if it's 1/2 or 3/4 you can leave it closed for a few laps so it feeds water in but you have to try and balance the water and steam pressure because when cold water goes in it lowers the pressure. I find when running for an hour I will only open the bypass a few times for a couple of laps or when it starts priming which is when water starts getting ejected out the chimney. When you've finished steaming, at the bottom of the sight gauge glass there is a copper pipe and a handle, all you have to do is turn the handle and it will eject the water and steam from the boiler, to avoid it going in the cab I usually put a small piece of silicone tubing (like that used for nitro engines) on the pipe and then open it so it drains away from the engine but be careful as it's hot and could scorch you easily.
Hi, should I open the blower or close it while it is running ? The manual said close it , but I don't understand why . Thanks
