Work continues on a $2.8-million project to add additional signals to the Caltrain signal system.

A $2.1-million project to improve the radio communications system that operates the signals and switches on the railroad tracks is underway. The project will add a second radio channel, which will increase the system's capacity. Work will take place Oct. 17-23 between the hours of 7:00 p.m. and 4 a.m. at several locations near San Francisco and the Diridon and Tamien stations in San Jose.
