Dumb question….but why is Caltrain adding more signals?

In December 2012, Caltrain started construction of the second phase of the Signal Optimization Project to place into service additional signals in the cities of San Mateo and Redwood City.

Lead Agency: Caltrain

Contractors: Transit Constructors LP

Project Limits: San Mateo to Menlo Park

Construction Cost: $549,000

Began Construction: December 2012

Completed Construction: May 2013

Caltrain is already spending one-quarter of a billion dollars on a new PTC system. PTC cab signalling largely eliminates the need for trackside signals. Not having to spend money on maintaining trackside signals was supposed to be one of the benefits of the PTC system.

And no, this isn’t because of some stupid FRA rule. The FRA has signed off on signal removal by other railroads with PTC.
