From a link at Gscale mad by otter 1   

 

I am amazed at how much to my untrained eye these pictures at the link .......look like the LGB models .

 

There are several photos that could just as well be a great outdoor  layout with LGB trains .

 

 

I enjoyed this link .

 

 

They look like them as they are them, much of LGB's stuff is of Austrian prototype.  Good post and good eye.  Like the "primer" version of U1 myself, and yup, LGB made a modell of it too!

 

 

Spot on Jack. They were a later development of the U lok. 

 

The class is actually Yv, making them compound.  There were three built, all by Krauss Linz, in 1896.   They were expensive and the original rear bogie design was problematic, especially in backing moves, so they were rebuilt to this current form.  The three were the only ones built due to the expense and problems compared to the "Reihe U".

 

I suggest this book if you are interested:

 

Well, since we are on the subject of the U.....

The next (natural) step after the U and Yh was the compound Uv:

And then the ultimate U, the Uh:

Superheated compound, and the early ones had the Caprotti (driveshaft to poppet) valve system!

I have the Bachmann model of the Uh in H0e, (occupation era DRG markings) but all Bachmann did was do a new shell for a U chassis....
