Hi, Yes the Bachmann spectrum range is good but the prices here are steep. they have a lot of detail, and have spring trucks as well. Some of the details not well fixed- and can come off -the axleboxes have covers for example, .and they have been known to be loose inside the box.
With all their detail they MAY be best on an inside layout, whereas the older 1/22.5 stock is very strong, and can stand a lot of heavy use - they are also very good for parts for scratchbuilding!
You ask about buildings 1/20th buildings are quite large, and also expensive - I build my own and have to reduce the length of them, the rest is scratch built. I use PVC solid foam and plasticard?PVC strip (from PVC window suppliers) for detail work. The roof can be finished off in a variety of ways. Rather than repeat myself there is a building of mine described in the buildings section, a couple more are approaching completion at the minute as well.
The work is quite easy - the plans are a bit more difficult, I have some books from the USA with plans in them.
Also I would suggest that you possibly ask your local newsagent to get for you the American bi-monthly magazine 'Garden Railways which will give you more information on the USA scene. Plans ocasionally turn up in there as well, and there are web links for buildings and much more as well.
Logging is also covered in the magazine 'Tall timber', and the Australian magazine Narrow Gauge DownUnder.
Both are availabkle from Camden Miniature Steam Services' (

Yours Peter.
