Thought exercise - steam VFT

[dbromage@fang.omni.com.au (David Bromage)]

Here's an interesting paper exercise. Suppose a multi squillionaire had
decided to build a 200mph train between Melbourne and Sydney in the late
40s or early 50s with the technology available at the time. 

What sort of steam locomotive would have been required for such a service?

I've done some rough calculations, and yes I think it could have been
done, at least with today's hindsight about what did and didn't work.
You do need be a bit unconventional in your thinking, but the design is
not really all that radical.

Go grab the Tuplin, Cox and Nock books, a calculator and lots of paper,
then post your thoughts.

Cheers
