i just came back from outside where i layed down all my rails. the hole layout was 42 meters of rails. pics look not very good because of the late sun...maybe i do another layout tomorrow... our garden is not in a linear slope and every tiny little minihill made a bit of a problem. i will maybe go for a much smaller set up when playing with the kids outside...the best thing were my 1,20 meter straight rails - in 1 minute you make a lot of meters of perfect track...
