Thanks for your response Brian, much appreciated
Already gathered that the society appeared to be the only other option, but I didn't renew my society subscription this year (a conscious decision), so can't use Scalefour stores at the moment, although given the recent Exactoscale announcement (managed to get an order in today!), I will now have to reconsider.
Back to C&L, if you look at the 1m length option, the website states rail only half metre lengths. I'll give him a ring.
Kicking myself though as I got some bits off him at Wigan, but didn't plan or even think far enough ahead !!
