I have been producing railroad map books since 1998, beginning with Western Washington. Since then, coverage has expanded to cover twelve western states! The company and website were established in 2002 and the maps increased in popularity. I began using the business name Sonrisa Publications in 2003 as distribution of the books become more widespread.
All books are produced using USGS state base maps as a starting point. Specific railroad information culled from current timetables and news stories is then overlaid the base maps to bring into focus today's railroading. - Dave Cooley
