Seeing the cab forward posts regarding gearing, I wanted to post a picture with some questions.

I started a generic thread so as not to hijack the gearing post.

I am by no means even fluent on old 2 rail.

The picture shows a CLW cast PA,PB set I redid from rust and corrosion on top.  Second is a DM&IR Yellowstone of unknown origin.  Third is a Lobaugh cab forward as bought (is this one of the 12 to 24 known to exist) it is missing a ladder on the cab.  Is this a correct tender?  It did come off ebay.  Last is  a GMC 2-6-6-4 I changed the front end on and painted.  Finally the custom cab forward wood box if it helps identify.

Any info is new info to me.

Thanks

Hi Everyone.  Since I posted I have not had time to respond or take some more pics.  Tomorrow looks to be no better.  I will get some undersides of both the Cab Forward and the Yellowstone.

Does anyone have an idea on the manuf. of the yellowstone.

Thanks

We can guess, but again better photos - a shot of the locomotive, then a shot of the tender, then from underneath.  My guess right now is Lobaugh parts, but basically scratchbuilt.

The Lobaugh tender may be "correct" but it is not Lobaugh.  At least not from here.

I am familiar with the Lobaugh, Hines and some other old O manufacturer's names.  Who (or what) was Jablemann?  I have tried searching and not had any luck.

My Cab forward is (I think) an AC12, the Lobaugh pics I found was an AC8.  Was an AC12 made as well?

Any of you guys that really know this stuff considered doing a reference guide?  I'd sure be in for one.

Thanks

 

 

You could make the AC-8 kit into a -10,11, or 12 with piping and cab changes.  But yours is not a Lobaugh.  It is possible it was made by some other famous builder, say, for the Treasure Island layout.  I have a photo of that one somewhere; I will check.

Otto Jabelmann was the UP Vice President - Research,  who supervised the modern Challenger project with the Centipede tender.  Arthur Fetters was the General Engineer - Motive Power when the earlier Challengers were developed.  Now the two UP Challengers are referred to as Fetters or Jabelmann.

The postwar Lobaugh Challenger tender came with annealed etched sides.  Gentle finger pressure will cause them to buckle.  You can see the etched Lobaugh data plate on those.

 

Hello Bob ..nice photo of the cab forward ...however ..the layouts at Treasure Island were 2 rail ....  none of those funny outside 3rd rail sweeps ..see below for Cab Forward running at Treasure Island ...and Lobaugh catalog illustration ...Cheers Carey

That is a much better quality model.  The photo was given to me by Bud Cantlay (RIP), who told me he was there.  He was 20 years older than me, so he would have been 17 or so.  I just assumed . . .

One thing I have not assumed - Lobaugh never produced the GS-3, although a trailing truck casting was advertised.  

The locomotive in your photo is not Lobaugh, since production did not start until December 1941.  Possible it was a pilot model, I suppose.
