Oh, something I discovered while trying to work out what track I will need for the new part of the old layout. The radii on Hornby track is anything but accurate. 438mm turned out to be closer to 447mm. 505 is actually 514mm. No wonder my old layout was all over the place. That and my approach of " drop the track on the board, connect them and you are good to go", didnt help. I know most (if not all) on here, probably use Peco track, but just a word to the wise if any newbies go with the ol Hornby.
