This is my first 00 gauge micro layout. The dimensions are: 41cm x 65cm. The radius for these very tight curves is only...175mm !  I cut the rail with my standard side cutting pliers...and it works well for me. I cleaned the end of the rails with a small file before fitting the fishplates. Just one Hornby 0-4-0 steam loco with three short wheelbase wagons. And that's all ! No need for DCC, so it's only a very basic DC controller. I'm very happy with the result. I just wanted to prove to myself that I am able to build a very small layout with flexi-track. Right now, I have no idea for the scenery. But I'm working hard on it.
