Steam loco's part 3

I've been looking through http://www.visi.com/~spookshow/locos.html which is an amazingly useful site (and one which I should add to the sidebar) for inspiration on general layouts for putting together a steam loco chassis. The best stuff comes from the brass steam locos section.

The first is a very old loco from the 1970's, with an open frame motor, and a very simple chassis. This does show that things do not need to be high tech to work. it might be nice to come up with something better than the huge arse screws holding the siderods together.

The second photo shows a more up to date loco with a can motor and enclosed gearbox. It could even be a larger scale model
