It has produced some of the world's most beautiful engines - and its clean and energy-efficient qualities may now bring it to the fore again. Lyndon Shearman and Derek Rayner present an evening of news and films on the comeback of steam in various countries, on rail and also road, in this year's festival.

This will be on Friday 3 September, the night before the Vintage Rally, which will feature Lyndon's 150-year-old steam engine, 'Little Dragon', which he had adapted to burn logs.

Lyndon and Derek will be reporting on a range of initiatives from around the world- from Europe, America and India. They will be joined by Dennis Whittaker, one of the crew of the steam launch Gondola, operated by the National Trust on Coniston Water in Cumbria. Once operating on imported coal, she now burns logs made of compressed sawdust.

The evening, organised by Orkney Vintage Club, is being held in association with Old Glory magazine. Old Glory is Britain's best-selling steam and vintage magazine, featuring many aspects of national transport and industrial heritage. We'll be posting up more details, plus photographs, here.
