Smokebox: Union Pacific #119 4-4-0

[slick204]

I'm just learning to run this locomotive so I ran a quick drive with a small freight. I had auto fireman turned off. I was unable to add water to the boiler. I was getting water shooting out when I opened either feedwater pump try valve but the boiler level never went up, only down. By the time I got to the first siding out of town the bottom water gauge try valve was blowing steam! I think I had the water foot valves open, they didn't move when I clicked on them.

Any ideas why I wasn't filling the boiler? Thanks.

Maybe you should read the manual again.

OK, you managed to open the tender valves with K and L Key.

Since the injector update, which was released some time ago, you also have have to open the feedwater valves on the crosshead pumps with Shift+K and Shift+L.

If the pumps are working, you'll hear them.

If there was water shooting out of the try cocks (the ones sticking out of the pipes that go into the check valves near the front of the boiler), that means water was going into the boiler. You would also be able to hear the "clack-clack...clack-clack..." noise of the "clack" valves closing. If the boiler water level was still going down, you must have been using a lot of water to create steam. There are a couple of causes for that:

(1) running with too much cut-off. One way to check for this is to bring up the F5 HUD and look at "boiler pressure" and"steam chest pressure" (sic). If the "steam chest pressure" is constantly as high as the "boiler pressure" you probably need to shorten the cutoff (bring the reverser closer to neutral).

(2) wasting a lot of steam through the safety valves - if the safeties aren't just "feathering" but are blowing off a lot of steam (typically with the boiler pressure at 120+ psi), you can either use up more steam by lengthening the cutoff, or reduce the fire so as to generate less steam.

Another thing you can do on 119 and Buffalo is to use the live-steam injector. Make sure the injector throttle is open (do this at the start of the scenario and just leave it open). To operate the injector, open the injector water valve first, then the steam valve. To stop the injector, close the steam valve first, then the water valve. You can use the injector at the same time as the crosshead pumps.

Ah! You must have had the F4 HUD open. When the F4 HUD is closed, mouse-clicking on the tender's water valves will toggle them open/closed, but if the F4 HUD is on-screen, mouse-clicking on them doesn't work (thanks to a TS "feature"). Instead, you have to click on the "water" icon/button on the F4 HUD, which will open both of the tender's water valves at the same time. However, doing so doesn't open the locomotive's feedwater valves - you still have to do that with either the mouse (clicking on the two handles labelled "feedwater valve") or keyboard (Shift L and Shift K).

Basically, when using the F4 HUD, you would open the feedwater valves in the cab and leave them open, and click on the HUD's water button (to open the tender water valves) whenever you want to add water via the crosshead pumps. It's the opposite of what you'd do when running the loco without the F4 HUD, i.e. leaving the tender water valves (aka "foot valves") open all the time and opening the cab's feedwater valves each time you want water to reach the crosshead pumps.

There's nothing in the F4 HUD for operating the injector, so you always have to do that from the cab or using the keyboard shortcuts (Shift E to toggle the injector steam throttle, I to toggle the water and O for the steam).

Thank you both for the advice. I need to find time to go back in and check what I have open or closed. Yes, I was using the F4 HUD. I will check the feedwater valves.
So it does have an injector? The manual says it doesn't have water injectors. So I can use either the pumps or the injector? Sorry, I think I should know this.

I added the injector and the feedwater valves in the cab in an update that was released in early August and the manual was also updated accordingly. As a reminder, here's the change list from the August update:

1. Set a slightly higher speed threshold for allowing the headlight to be toggled.
   
2. Corrected the keyboard controls, R and Shift R, for adjusting the slider in the firebox that sets the desired fire mass.
   
3. Added an injector located between the left-hand driving wheels, together with the associated handles in the cab for controlling the supply of water and steam to the injector inlet pipes.
   
4. Added the front and rear damper handles protruding from the floor of the cab on the fireman's side.
   
5. Added handles for operating the feedwater check valves fitted to the pipes carrying water to the two crosshead pumps.
   
6. Added the ashpan door lever and its associated handle above the left-hand runboard, together with ash dust effect.
   
7. Relocated the blower control valve.
   
8. Corrected the texturing of the handbrake ratchet on the boxcars.
   
9. Placed the correct picture (the mountain man Jim Bridger) on the right-hand side of the sandbox.
   
10. For greater historical accuracy, removed the builder's plates from No. 119 but kept them on No. 116.
    
11. Added a shovel in the tenders.

There's been a further update, just last week, to fix the problem of parked rolling stock rolling away on a steep grade.

There is a new patch available for the UP119 sister locomotives /repaints by trainboi, representig UP No. 117, 118 and 120

This patch updates the repaints to the state of #119 like it is now (May 2019) and fixes the following:

- The names and numbers of the locos and tenders have been corrected so that they get the right names and numbers when you place them in the scenario editor.
- Like #119 the sisters have now functional injectors and the needed textures for them.
- The virtual airbrakes that have been added to all 1869 locos, to stop uncoupled coaches from running away on grades, is working now also in the repaints.
- Some textures have been added, updated or fixed.
- This package also includes some quick drive consists for freight and passenger operation.

If you already use this repaint, you have to insert a fresh copy of the geopcdx files, because these have been updated as the injector was added some month ago.
