I have been working for some time on a major announcement regarding the Onondaga Cutoff - and today, I can say with excitement that a full-length article on the layout will be published in Model Railroad Planning 2018!
Model Railroad Planning is a special edition, produced by the publisher of Model Railroader, once each year. It focuses on layout planning and construction, and that's exactly the angle that is taken with my article, which will be published in early January.
It's available for sale at https://kalmbachhobbystore.com/product/special-issue/vt-mrp180101-c
Best wishes for a happy and healthy New Year!
