OUTSTANDING
Thanks, HaJo !!
Hi Klaus, Thanks a lot for your comments and points 
Hi hänschen, Thanks! Yes, It turns out to be... very big... (maybe too big) Still trying to find the best place to put it. 
Congratulation, this is the best steam locomotive model I have seen over the past years.
Many thanks for showing us your construction report.
Hi René, thankys a lot for your kind words and very glad to know you enjoy the build.
Amazing pics of your black beauty! I love this incredible firehorse!
Many thanks for this report and two years of practise one of the finest arts of papercraft I have ever seen!
If you come back with a new Projekt, I will be your guest again... of course!
But now lets celebrate your great masterpiece!
With kind regards from good old germany!
Hi Matthias, Really glad to know you like the build. Surely, I will be starting something, but I'm considering something smaller next time. 
One can't say it better...
Hi Fiete, haha, Thanks a lot !
With few words, a masterpiece! I like it
Hi Robson, Thanks a lot !
Hi Reinhard,
Thanks !

this is, without a doubt, one of the highest quality models i've ever seen on our forum with a construction report to match. Thanks to the slight sepia tint some of those photos could easily be confused with an old postcard from maybe the 50s-60s.
I applaud your skill and truly hope that this won't be your last locomotive. But no matter what you decide to tackle next, i'll certainly be watching!
Hi Johannes, Thanks for your comment. I cannot be sure when, but I also hope I make another locomotive in the future. Anyways, I'm thinking about some model that is relatively smaller than locomotive
Wow, Thanks a lot, Christoph !
Great to know you liked the build and pictures. Thanks Henryk !
Hi Peter, Thanks a lot for your comment !
Hi All,
Thanks a lot for your support so far.
Let me share a bit more pictures.
Perhaps some of you have noticed and wondered about the locomotive numbers 307 and 110. Initially at the beginning of the build, like I did when I was building Py-27, I was concerned about the possibility of failure and thus constructed two locomotive frames. Later on, I changed my plan and decided to build two Ty-2s for my daughters, even though I am uncertain if they will want the locomotives in the future. Nevertheless, I find comfort in knowing that I have created something for them with my own hands.

And followings are the size comparison with my previous models.

Thanks a lot.
Have great days.
