Presently, I am modeling a modern freight/passenger type layout. Nothing remotely European about my railroad. However, I did a modern European railroad in "G" gauge and had 5 modern Taurus locomotives. Two of which ran counter opposing. I had one 8 foot track and one 6 foot track. The Piko Taurus can run minimum 6 foot and is quite impressive when pulling a modern consist of German freight cars. I had some of the best of the best as far as that goes. Piko, LGB.
I wanted to model in O, but found little in the way of really modern. I even had one ICE (Inner City Express) high speed train in G on that layout. It was really quite impressive. With snow covered fur trees it looked like a typical Austrian/ German ski village scene.
I love all trains period regardless of where they originate from.
