There are a couple of older Kalmbach books that are worth keeping an eye out for ...

Easy-to-build Model Railroad Structures  Edited by Willard V. Anderson printings 1958, 1960,1963

very basic structures - aimed at HO modelers but with good drawings - some labelled with prototype dimensions; some not

Scratchbuilding & Kitbashing Model Railroad Stations  Edited by Bob Hayden 1978

just what it sounds like- lots of station plans from old MRR mags

Also, keep an eye out for copies of standards books.  I recently picked up a copy of the Virginian Building Standards.  These books are available from many historical societies and are filled with blue prints labelled with prototype dimensions.

Cheers,

I actually had the first book you mentioned, but it seems to have grown legs and walked away.......

Thanks for the info.

Model Railroad structures from A to Z By Wayne Wesolowski is one of the better scratch building refernces, it was out of print for years but I see Carstens (Railroad Model Craftsman)has it on their website again. It has project plans and sugested technique's. Otherwise unitl we get scratch building articles here, take a look at the index of model railroad articles at http://index.mrmag.com/ and punch in "scratchbuild building" as the keywords. Most of the articles are availible as a reprint for a modest fee, if the magazine is still in buisness. It may be a challenge to convert some of them to modern materials, but some of the old techniques still work well.

Good luck and post pictures
