Dear all,
I have a Roundhouse Lady Ann locomotive which has 'Simplified Walschaerts valve gear'.
In regards to the 5 inch gauge Welshpool Resita I'm building, would it be ok to use a simplified Walschaerts gear on a larger model?
From the basics I understand that it can't be notched up so I'm looking for some advice.
Any ideas will be much appreciated 
Regards,
Tom
