Hoping that I can find a reason for us to go down to Southampton this weekend so I can slope off for a while to Eurotrack. I would very much like to see this layout and it looks as though there may be a few other good ones there this year.
When using a razor saw, you really want to be holding down the track with a wood block slotted to grip the rails. Certainly used to be possible to buy such blocks but not difficult to make your own.
