Yep, i made it longer and wider, i added 7 inches to the width and 40 inches to the length, that's about as big as possible without having to slither along sideways to get in
Ken yes the points are Peco insulfrog, i'm happy useing them instead of the electrofrog type. the board is 9mm MDF, it's easy to work with and the pin's hold rock solid. I didn't put any roadbed down as i want to have the track almost level with the surrounding ground, it will look very wild and overgrown (in time)
