Modern steam

In practise

No steam locomotive ever built included all the available proven techniques to maximize its performance in service.
This fact, more than any other factor, is what lead to the downfall of world steam.



That all this is more than just theory is proved numerous concrete cases. I don't pretend to be complete in the following list I will extend it in due course.
The links lead to more cases.

South Africa rebuilds a Class 25 with great effect (SAR Class 26).

2006 - Mount Washington Railway converts one of its old rack steam locomotive to bio fuel firing making it effectively the worlds first bio-diesel steam locomotive.
Today - There is still a small group of dedicated engineer involved in improvement of the Stephensonian steam locomotive. In 2006 a conference in York  was held. Jos Koopmans presented his theses on improvements of the exhaust
    Detailed plans exists to create new steam locomotive based on these modern concepts
  - Development of an entirely new class 5AT
  - Building a fully new Peppercorn A1, a class of which all members have been cut up in 1966
  - Today DLM, a dissociation of former SLM, under Roger Waller strives for building new steam locomotives

These developments are more than just nostalgia. They hyper modern machines
