Western Pacific GP20

[Geep20]

Awesome addition for the Feather River route. I was just wondering the other day what happened to this GP20 model since it has probably been finished for quite some time and was shown around the time the marketplace schemes were added.

Now if only the ATSF version would magically appear somewhere to buy I would be a happy camper.

Sales of the ATSF version are unlikely as it would be a BNSF licensed product.

Yay, this loco will have an advanced startup like the one from reppo Something we need on more engines!

Did you read anything about advanced braking?

I did not, but I quickly read through it so not saying there won't be.

I have the Repo SP GP20 and I think it was one of the first if not the first to use scripted braking. It works better than Mikes version actually.
@Buzz Yes, after I posted last night, I did some more research on that and found out what you were saying.
Even if W.P. or the museum hadn't made the change, the U.P. probably would have required it for running on their tracks, which happens from time to time.

Ya I know this all too well, but one can dream that MAYBE the repaint shows up on some other website at some point. Not necessarily through DTG.

You mean aside from the fact it doesn't have brake pipe length propagation, the right release or application rates, or actuation? Yeah works great.

or independent brake bail-off

or break-in-two detection with PCS ...


I could go on

I all know is they work smoothly.
I have a problem when using Mikes engines in which I try to grab the brake lever in the HUD and the lever frequently refuses to move in any direction. It just "vibrates" for lack of a better word.
Some engines have the same problem with the Dynamic brakes when trying to move out of setup, even after 20 or 30 seconds.
The U30Bs that come with Feather River are really bad with the scripted brakes doing as they please. I've moved the train brake to release them more than a few times and they just don't want to release. The lever just "vibrates" up and down a bit and refuses to move.

I think I may have experienced that too, try moving the mouse in the opposite direction from the intended movement of the lever, I'm pretty sure I've seen some behave like the axis is reversed, it may have been different equipment but still worth a shot.

* I see you said HUD, it happened to me in the cab.

That's the simulation of the detents in the brake quadrant. You're supposed to let go of the lever for half a second before moving it again. The lever isn't meant to be able to move smoothly from one extreme to the other, because real brake levers don't. It's also designed to help you avoid moving the train brake lever beyond full service application and all the way to emergency without even feeling the detents that are there precisely to allow the engineer to feel the limits of each zone and stop that from happening. Without the simulated detents, you'd be able to slide the lever in any direction, and amount, and you'd have to rely entirely on looking at the percentage travel indicated on the HUD. If you weren't using the HUD at all, but using the keyboard and/or the mouse to work the lever in the cab, it would be even more difficult.

All of this was explained in detail in the manuals for the FEF-3 and Connie, which also simulate brake quadrant detents, but unfortunately it doesn't seem to be in any of the diesel manuals, which is a great pity (because I find myself having to explain this stuff over and over again).

That's because the lever has stopped at another detent before "Release". You have to let go for a moment, then continue. This is designed to help you avoid releasing the brakes accidentally when you only meant to move the handle from the application zone to lap.

[mrennie]

It's a real pity that none of this stuff about detents is described in the manuals.

The full set of detents where the script prevents you from passing the detent without pausing are as follows:

Automatic train brake:

- At "Initial Reduction" when moving towards the "Application" zone

- At "Full Service" when moving towards "Emergency"

- At "Hold/Lapped" when moving towards "Release"

Independent brake:

- At "Release" (the 20% position on the HUD's lever) when heading towards the "Bail off" position. Also, it's spring-loaded, so if you're in Bail-Off and let go of the lever, it'll spring back to "Release".

My issue was something completely different then, I don't recall the loco I was driving but it had nothing to do with detents, I'm pretty sure it was an older release without advanced braking though. Using cab controls if I 'pulled' the mouse towards me as the model was designed the lever bounced a bit and did nothing, if I 'pushed' the mouse away the lever moved towards me and the brakes applied. I've run into the same thing with sunvisors sometimes too.

Yep, that's a different problem entirely. Maybe something to do with the axis being inverted?

Definitely a first day purchase for me. Reppo is one of the best locomotive modelers around.
