Connecting the rail designers, builders, and operators in Southern California FOR OVER 25 YEARS

The Railway Association of Southern California was formed in 1996 for the purpose of bringing together railroad professionals in the Southern California area, dedicated to promoting the diverse professions within the railroad industry and sponsoring fellowship among railroad professionals.

In the 25 years since incorporation, our membership has grown to over 300 individual members attending monthly events ranging from luncheons to seminars to site visits covering railway design, construction, and operation in Southern California.
