Very clever in how you have modified a clear tunnel to a mountain tunnel entrance. And it looks like you are using subway tunnels stood on their ends as high rise buildings...right? Is there more modifications coming for the station? What are your other Advance mods you are planning? This engine looks very familiar to me. Have I seen your work elsewhere?
Yes I have a facebook group which some will be familiar with. As for planned mods. I have in mind......
an Intercity 125 and maybe a JNR DD51 both in Advance. Details will follow.
I have a Virgin Express awaiting plastic surgery (get it?) to turn into a Pip and Emma but I need another motored side of the train because both Pip and Emma are powered.
