Hi. Does anyone have the tech specs for this Loco? I downloaded it from Steam Train workz into 2012 but it needs a new e-spec to run in 12, hence the need for the specifications. They are not on wikipedia where one can usually find them nor can I find them on the two major D&RGW historical and enthusiasts web sites. Is there anyone out there who would have it or know where to get them? e. g. driver wheel size, Tractive effort, cylinder size firebox etc. Someone has made a nice job of the loco itself It would be a shame if we cant get it to run/sound OK in t12. Cheers

Edit: Forgot to ask, What cab are you using on the K11? Is it Bens original USRA cabin and does your addition to the e-spec fix the t12 problems with it or are you using another cab also?

Thanks to any of you that have looked. I think I have a lot of the specs now after a day on the internet. It seems to be a remake of the Ben Neal loco NYC K-11 and while it is not on wikipedia either, there are one or two sites that have bits of info on it that I can pull together. Seems strange that a loco type of which many were built does not have a lot of info on it out there. Cheers
 
Steamlocomotive.com is always to first place to check. K-11 specs are on this page.

The steam section (below) works OK for me with the K-11, although it could use some tweaking of values used for the firebox-heating-surface-area and max-fire-temperature containers. It's a slight modification of results obtained using Billegulla's enginespec spreadsheet. However, it probably doesn't reflect real world specifications for the prototype K-11 locomotive in regards to boiler or firebox size.

EDITED/UPDATED: The config below actually works better than what I posted earlier...

Thanks. While I ws playing around trying to find the info I downloaded the NYC K11 from Ben's website as well. Aftre discussing it with Bill69, I finished up putting the Blue comet e-spec and Auran cab in the D&RGW P-44, with the Billegulla sound and it goes well in t12. Im going to modify the K-11 the same way however I'll put put your spec in the K11. Cheers
