|Called "Revolution", this is
a proposed steam locomotive design for
heritage service in the UK. Emphasis is on
low cost/high reliability rather than
maximum performance and thermal efficiency.
The intention is to first build a 10-1/4"
gauge demonstration/test locomotive before
building full-size locomotives. Some parts
have been completed for the 10-1/4" engine.
