Roger G. Burrows has written a wonderful 150-page book, rich in maps and black and white photographs, that includes the Great Northern lines in southern British Columbia, concentrating on those east of Hope. He is currently working on a volume specific to the railways of the Fraser Valley. Published by Railway Milepost Books (4398 Valencia Avenue, North Vancouver, BC, V7N 4B1, Canada), volume II (pictured) is available from that address for US$19.95.
