Well i might give it a try, i think last time me and my granddad tried a 2nd layer (was many years ago) most of locos we had were tender driver and just couldnt coupe with a 2nd layer. If i do a 2nd layer i will certainly have to alter that one abit as that would come over the lift up section.
You certainly make a good point about illusion aspect which i have noticed when going to exhibition, cheers for the input John
Well tomorrow will be a busy day! now just have to make a list of what extra track i need!
