My grandpa's huge selfmade model railway.

Today I want to show you my grandpa's huge model railway.
He has been building it for the last 40 years. All the trains, tracks and accessoires would have a original value of 250.000$ today!
Unfortunatly he is thinking about to sell the whole thing, because his eyes are too bad now for playing with it. That's the reason why I originally made these pictures.
But first I want to share it with the steem community. Take a look at all these details! I love it since I was a child. Maybe more fans of it are out there :)
