Description

This list intends to be a starting point for the exchange of information about steam locomotives, specially from the technical point of view: this technology is disappearing but at the same time, new developments are made...

Typically, it should offer information about...
* tips for rebuilding steam locomotives and/or sub-assemblies and parts,
* sources for this technology,
* information about new solutions for modernizing existing steam locomotives,
* emerging renewable energy sources for use in these locomotives (see current experiments and ECOVAPOR XXI event in July 1999 in Cuba, etc...),
* just history... or books about it...
* why not drawings, shop manuals ?
* we expect to centralize sources for documents written by L.D. Porta and others...
* the growing success of tourism-oriented steam train operations, what it implies in terms of steam traction,
* "steam related events": "specials" or "Plandampf",
* records of steam locomotive rebuilding and/or modernizing,
* records of new construction (!),
* existing survivors, either "still in operation" or waiting for... better days (?),
* etc...

Some fun too: we hope that we will talk about Garratt's and Mallet's, about weird things like Golwe's ... or Shay's.

Information about other reciprocating steam machines are welcome...

Primarily full-size "1/1 scale" units but steam technology applied to miniature steam (live steam) is OK too: additionally, they are attractive test-beds for the development of "1/1 scale" solutions...

Business-oriented messages are OK (provided they are in relation with "steam" topics...).

Messages should primarily be written in english but other languages are OK, provided they use the same letters/signs...: if you post a message in e.g. french or german, please add some english translation or summary...

Re Large Valves,ATSF 2-10-4s and Valve Setting
Gday All Not one of you have mentioned the Port area or width either on its own or in conjunction with Cyl Vol or Piston area. Lap and Lead are meaningless
