Schienensicherungszug Blücher a new 1/144 train on its way 47/52

at the moment I try to finalize a new train model for one of the German Panzerzüge.
The waggon is very interesting as it's a combination of German and Russian train material. The main frame is a Russian waggon, built for the Russian Panzer trains. The Germans catched it and built on top a closed cabin with Russian tank turrets. For a short period it was used with a T-70 and T-34 turret, but later it changed to an Panzer IV turret.
If you look for more information, two of these wagons were part of the Sicherungszug Blücher, or Panzerzug 51.

Here some sources, where you can find more information:

And here a preview of my design. I try to get it finished for thanksgiving, what is very competitive.
