Have a look at ge_rik line where he has a short 32mm feeder line to a quarry loader on his 45mm line.Should I now admit something sacrilegious? Further thoughts on the replacement raised layout have brought up the possibility of 32mm rather than 45mm!!! Definitely not giving up 45mm but I have a very large collection of O gauge plus some SM32 which these days rarely gets an outing. Please do not suggest dual gauge as I really desire simplicity. Still need to work out how to have both but now PIGSEAR has been pulled up the push to proceed has strengthened.
Wish me luck
