Update on the steamers

[dtrainBNSF1]

Well I'm happy to report that the GS-4 is DONE I'll probably get around to submitting the mod for publication in a couple of weeks - I have to get through finals week.

Meanwhile I've already sent Berkshire mod 3.0 off for testing and I'm looking for a volunteer to test SP&S mod v2.0.

The K4s is coming along. I'm still doing speed testing to get the effectivity right which is taking a while because this loco is sensitive . It's a project for sure.

The Cab Forward is practically ready for testing. It's been a bit since I drove it last, so I'll have to see just how ready it is, but expect an announcement for testing the Cab Forward in the near future.

Billy: How's the latest simulation folder I sent you for the Big Boy treating you?

Whelp, finals are over and I'm now on vacation until June 8th. As far as the latest mods, everything seems to be coming together. I just downloaded the C&O Kanawa repaint of the Berkshire and I noticed that particulars about its physics are different from the NKP Berkshire. So I'm going to make an alternate simulation file for that loco. Also I've been looking at the Erie weathered Berk I downloaded a while back. I'm supposing that it is an Erie Class S-2 as the NKP Berk in TS2015 is an S-2. Doing a little digging around I've found that it too differs from the NKP Berks in physics, so the Erie Berks will be geting their own physics update as well.
More projects for me. I actually enjoy this hobby

As of this morning the GS-4 has been submitted for uploading to the site and sometime in the near future should be in the file library. The mod does apply to all variants of the GS-4 included in the pack from Steam. The loco features a booster which ensures 100% tractive effort up to 20mph. The loco can now travel up to 110mph (the schedule never required the loco to travel faster than 75mph).

Now I am calling for someone to test out the latest version of the SP&S E-1 loco and the SP Cab Forward. The testing will only be on SP&S 700 and the clean variant of the Cab Forward.

I just finished modifying the Pere Marquette berkshire repaint. I would like to ask for someone to try out the mod before I upload it.

Happy Memorial Day everyone!

Looks very good to me.

Looks very good to me.

Thank-you Billy

By the way, how's the Big Boy mod I sent you treating you?

[billy]

Very well !! That version, for me anyway, runs very good. Thank You.
I've been spending most of my time on the VNHRR trying to make a few steam scenarios.
but its very slow going when you can't remember what you just done or have to repeat the process over and over before it finally works.

Glad to hear that

You can get very close to the actually car count the Big Boy's pulled at that time.
And that's what I like !!!!

Check out this Challenger on Archer Hill.
Most everyone underestimates the power of the magnificent machines.
Note he running solo with no power assist.

EDIT :
Oh ,yea B,
I was messing with Cab Forward on Marias pulling extreme long and heavy and I was able to max out steam generation at 142,000.
Very similar to they way the FEF-3 does.
I had Uncle Joe here watching ( 91 year old former Illinois Central Steam Locomotive Mechanic )and he believes this is the most correct way to simulate real operations. According to him, steam generation will continue to rise as long as there is fuel and water. The cylinders will consume all that is available under heavy load and this is how they where able to move such heavy trains solo.

If we could figure out how these 2 locos are able to do this and apply it in relative terms to the others, I think the performance will get much more realistic. He said the IC Berkshires & 4-8-2 Mountains could pull as much as needed and nothing larger was required due to the relative flat ground on the IC routes.

Talk about underestimating the power of a steam locomotive! Take a look at this:

That's exactly what I'm talking about !

Here's a pic of 700 at Whitefish on an early fall morning in 1955 in a scenario I'm writing for the modified loco which I may include with the mod download if I figure out how to include scenarios. For those who have had the 700 for a while, see if you notice anything different in this shot

As far as steam production in the boiler, I calculate that with a couple of formulae mrennie gave me a while back:

theoretical maximum rate (lbs/hr) = boiler horsepower x 34.5. This product is then multiplied by .65 to take into account missing tubes, flues, etc.

1 boiler horsepower = 34.5 lbs of steam per hour

Boiler horsepower = (1/6) grate area (sq.ft) x boiler pressure (psi)

How that applies to the Cab Forward then is:

(1/6) 139sq.ft x 250psi= approx. 5791 boiler horsepower
~5791 x 34.5= 199812.5
199812.5 x .65 = 129878.125 <- This here would be the "MaxOutput" that I would put in my modified Cab Forward's sim file.

No feet dangling? Looking forward to this mod, and the scenario. Will you also release scenarios retroactively for the SP 4449, and Big Boy/Challenger?

Scenarios for the 4449, Big Boy etc. I'll probably post directly to the library.

[dtrainBNSF1]

And yes the feet are no longer dangling from the cab
