The Cost Savings of Steam Today.

[NW Mailing List]

People who may well have looked at some of these issues are the A1 Steam 
Locomotive Trust in the UK - see limited details at 
http://www.a1steam.com/design.html - who are engaged in building and 
then operating a Peppercorn A1 steam locomotive on main line and 
preserved lines.

Tornado is close to being complete, and due to enter mainline service 
this coming September.
