By photoshop I was refering to the clone stamp tool you used and thought maybe you were hiding something good.
The hidden is not (very) interesting. You can see all in the last photo (it's a right curve). In the first photo the rails are not assembled (looked wrong).
Thank you for your interesting details (about your grandfather)!
What grade is that train going up? looks steep.
Yes, you are right. The brigde is not yet finished and unfortunately our garden is very steep. Also this loco with only one motor can't pull 10 wagons! It's only for the photo.
I will also use two cabooses in my train !!!!
That's the reason why I put 2 cabooses in this train. (and also cause I have 2).
