The benchwork is modular, based on the Battleframe series of modular games table bases by Back 2 Base-ix, though if I was to try again I would NOT have a layout this small modular, with nothing to align the track but the flatness of the tabletop.The magnets used to connect these things are strong, but have this annoying tendency to not fit in the holes correctly. It would also reduce disconnection of track.
The underlay is 1000 gsm paper, as I cannot get any cork sheet.
The track is all Peco.
The plan is from a supplement from Railway Modeller, altered as I didn't feel like trying to build a sector plate my first time, and to fit the track features into the modules better.
I still think I should use insulating joiners to join the left end module tracks as the gap seems too wide, the wagons can run over it but even with some weight in them and at low speeds it will not look terribly convincing.
Suppose I should just call it a "chainsaw", for now...
