I am setting up my O27 train set for the first time since I was a kid, but now I have the resources to do it right. The layout I have set up is about 8 ft by 12 ft. There are 3 loops(50 straight pieces 35 curved) and 12-14 switches. I purchased an 80 watt transformer to power it, but it is clearly not enough. I need to know how much power I am going to need before I start purchasing more equipment.
Thanks
Dave
