I will be 76 this month. Got my first train set when I was 6, even believed in Santa then, it was a Hornby 0 gauge set that ran on a wet lead acid battery, had to take it to the local post office to get it recharged. My last model train was an N gauge set that took up most of the garage, couldn't even get the car in. My working life was in engineering, working on everything from sewing machines to ships. Bought my first personal computer in 1972 and kept updating until last year, my current computer is Win 7 64bit with 8gigs Ram and 2gigs Dram. I retired at 70 and am enjoying the life of leisure. My first Trainz 1.1 was found in a bargain bin in The Warehouse and though I kept updating I always waited till at least the first update was available. I still sometimes work on preserved steam locos here in NZ and find Trainz keeps my mind active. My favourite pastime in Trainz is getting the AI to do what I want it to do, I have been working on a prototype route for some time now but get a bit bored with it and branch out to other activities, so I don't know if it will ever get finished.
Cheers,
