Greetings all :thumb: Quick question.. I am going to build a small minimum space HO layout with Sound and DCC and the works.. yes I know N-gauge for 30 years and now I try playing elsewhere , so call me stupid.. it will be one of the better things I have been called over the years. I am going to build the layout as a jigsaw layout, so there will be a flat base of plywood and then jigsaw pieces cut to match the depth of the track bed on top of the plywood so I can vary the scenery to change the layout.. initial plans are GTW/CN steam/diesel 1940 - 60 and UK Great Western around 1930's - 40's (Remember I said you could call me stupid? ). My first thought was to use Homasote, but when I went into my local Home Depot up in North Toronto the guy looked at me as if I had just sworn and said.. never heard of it. Sooooo is Homasote available in Toronto, and if so where. I am actually in North York/Markham, but have car will travel Regards and Thanks in advance.
