All, Next on my list is contruction of the station platforms. I have two different scenarios. a single platform on a single track which is required to be straight and constructed on a flat surface. The other is an island platform, again on a flat surface, with one side straight and the other curved. Australian platform prototypes are the height of the carraige door level. How should I build the platform up? what should I use? timber? construct the edges and fill with plaster? Remember I need a specific height. 9/16" above the railhead. (NMRA Standard S7) And what should I surface the platform with to get a good surface to work with? Thanks, TOOT!
