I had a go with building a platform from 2mm sheets & 3x10mm Balsa Wood sticks. For some formal recommendations regarding platforms sizes and clearance see my earlier platform article and NEM102/103 for clearances.
Pitfalls & recommendations for platform clearances
My own recommendation for clearances, if you are not running steam locs, is to run with the widest trains and in sharper curves also with the longest carriages before building. However, if you intend to run steam engines – as I found out, they may have the cylinders and drivers stick out further than anything else and then, because the manufacturer has given each axle quite some play to deal with tiny curves, the loc can stick outside even the already wide official clearance profile (about 7mm from the outside rail).
Luckily Balsa wood is easy to cut with a sharp knife so you can correct it all somewhat if you do get into trouble.
