My G scale is indoors, I went to G from a OO layout in 1993. What was a fair size OO layout in my small second bedroom became a a very small G layout with a single line a station with loop, three sidings & Loco Depot. A halt was added later on the single line. I operate it as I always have, my job on the railways was working out train drivers/guards workings (diagrams) So on my layout on the basis of 3 or 4 circuits per mile/km I can drive a train on any line in real time. This week I am doing the Waidhofen to Ybbsitz NG line in Austria to the 1998 timetable. In a few minutes I will be driving the 0922 Waidhofen to Ybbsitz & 0950 return with one of my LGB Rhb Railcars the nearest I can get to a 5090 unit. It will be 34 circuits & take 27 mins. I do lines from all over Europe many which have closed years ago to get a feel what it was like to drive those trains. Doug
