That's a huge roundhouse...just like their late steam engines which I love. I have a Q2, T-1, J1-a and S-1. I first remember seeing a Q as a model in the mid-50s at a long-gone train store in Philly, Les Meyers. It was (I think) a Max Gray O'scale model and it burned itself into my 10-year old brain. The T-1 was imprinted in my impressionable brain since the demonstrator version was beautifully drawn in George J. Zaffo's Big Book of Real Locomotives where the pictures were all huge pull-outs. In that book also was the GG-1 and the Alco PA Santa Fe. Nuff said! No wonder I had to have these engines on my layout as an adult. I had no choice. It was out of my control.
The decision to have or not have a roundhouse was made long ago when I first designed the layout. By leaving the center open for access precluded having the roundhouse. So now I'm stuck with a conventional diesel style design. Luckily, I have enough ways to turn steam engines around without having to pick them up and manhandle them.
