On Friday 5th October, John Hind (Chairman of the 5AT Group) supported by Mike Horne (Secretary of the Group) made a presentation to the 1st International Congress of the World Association of Tourist Trams and Trains (WATTRAIN) held at the National Rail Museum in York.  John's presentation was titled ‘Steaming into the future with Sustainability’.

The presentation outlined the origins of the 5AT Group and what it had achieved with respect to 5AT Project and how the knowledge and experience gained from the work can be put to future use both in the building of new improved and more efficient designs of steam locomotive, and in the development of improvements to existing designs through the application of the Fundamental Design Calculations (FDCs) that were produced by David Wardale for the 5AT.

John spoke specifically about the possibilities of reducing emissions and operating costs, for instance through the use of improved exhaust systems (such as the Lempor) and improved valve and piston rings and piston/valve rod glands to reduce steam consumption (through improved steam tightness) and increased component life.

John also outlined the preliminary trials that the 5AT Group had recently undertaken to assess the viability of a number of (solid) bio-fuels in miniature locomotive fireboxes, with a view to reducing emissions, and perhaps even implementing carbon-neutral combustion.

John concluded his presentation by revealing the plans that have been put in place for a joint undertaking between the 5AT Group and the Heritage Railway Association (HRA) to conduct a survey of steam loco owners and operators including all HRA members, to assess where the industry sees its greatest technical challenges over the next 25 years, and to help the 5AT Group to plan how it might most effectively target its efforts towards the future sustainability of the heritage steam traction.
