Like most everyone else I have limited space but lots of desire..I am 52 (I still can't believe it !!) and need and use reading glass's..My interest is in passenger trains with of course looong cars...I have an area for a layout approx. 4x12 or less to share half of a sewing room...(Spacemouse you have been quite an inspiration for me !!) The advice I am looking for is for my first real layout, I researched and found the Dec 94 edition of ModelRailRoader to build the Soo Red Wing Division,in HO..But again, passenger is my "druthers"..With the limited area to 18/22 inch radius would I be better off in N to accomodate those longer radius's for passenger cars and depots .??
