Thanks for adding me as a new member of this great community.
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.
