BART COMMUNICATIONS-BASED TRAIN CONTROL (CBTC) PROJECT
SF Bay Area, CA

The BART CBTC Project is all about modernizing the way trains run in the Bay Area. Right now, BART still uses an old-school signaling system from the 1970s, which limits how many trains can run and how flexible the system can be. With CBTC (Communications-Based Train Control), trains will be able to talk to the control center in real time, allowing them to run closer together safely. That means fewer delays, more frequent trains, and a smoother ride for passengers.

​

One of the biggest benefits of CBTC is that it will help reduce overcrowding, especially during rush hour. The current system relies on fixed sections of track to detect train positions, but CBTC constantly tracks each train’s exact location and speed. This means BART can run more trains per hour—potentially 30-40% more—helping to cut down on wait times and improve reliability. On top of that, the system comes with built-in safety features that help prevent accidents and make operations more efficient.

​

This is a big project that will take several years to fully roll out, and BART has to do it in phases to avoid major service disruptions. The agency is working with experts to design and install the new system, and while it’s a big investment, it’s a necessary one to keep up with growing demand. Once CBTC is fully in place, passengers will notice a big difference—smoother, more predictable trips and a transit system that’s built to handle the future.
