Burlington Northern Santa Fe Railway Heritage started in 1849 with the opening of the Aurora Branch Railroad in Illinois from Aurora to Chicago's west side. This grew into the Chicago, Burlington & Quincy, which in a 1970 merger with several railroads became the Burlington Northern Railroad. A 1995 merger of the Burlington Northern Railroad with the Santa Fe Railway created the Burlington Northern-Santa Fe Railway, the largest railroad in North America at that time. This book carefully covers the heritage of this very successful railroad.
