I should add that the building of 'Calverdale' saw use of the then new Peco electrofrog points and what a tremendous improvement they made. I'm sure they were the most significant reason for the near elimination of locomotive stalling.
But as the time drew near for 'Calverdale's' withdrawal from the exhibition circuit the need for another layout grew ever stronger. By this time Mark, now fourteen and a valued member of the Calverdale team was considered old enough to enter a Father/Son liaison to help build the next layout. We decided to model a Great Western type branch terminus, as this was considered neutral territory to both of us, me being a firm LMS man, and he (as it later transpired) being a diesel enthusiast (more of which later). This then became layout number four, 'Nether Stowey'.
