Dr Richard Furness has been interested in railways from his earliest recollections. Living close to the railway lines in the historic and industrial part of East Shropshire, he grew up to the sights, smells and sounds of the steam locomotives. He is better known as a leading international expert on flow measurement. He is currently the only person to hold Fellow Status in both the American and UK professional engineering societies in Measurement and Control. Writing books on railway-related subjects, as he has been doing for the past 15 years, is the evening job! He is the author of the successful and critically-acclaimed Poster to Poster series.
