No railroad content, you say. Well, it is thanks to these Call Boxes that the following photos were made possible. My last job was with the Service Authority for Freeway Emergencies, or SAFE, Although SAFE had substantial funding, it was very small (while I worked there, 1996 through 1998, my boss and I were the only full-time employees), so it was made part of the Los Angeles County Metropolitan Transportation Authority, commonly known as the MTA.
