Why this matters: Both of these routes build in 15-20 minutes of downtime into their schedules to wirelessly recharge battery electric buses at BART. However, the battery electric buses break down so often that they rarely ever run. If County Connection could just run diesel buses instead of battery electric buses, or charge the battery electric buses more quickly, or run a full day's service on an overnight charge they could reduce scheduled headways and run bus service more frequently.

Other bus agencies that have reduced headways from 45 to 30 minutes (the 5 bus) or from 15 to 10 minutes (the 4 bus) have seen ridership increases of 10-25% on those routes.

Diesel "Wasted Time" at BART

The Route 4 schedule allocates 40-minute round trips, but actual driving time is only 23 minutes. The extra 17 minutes per round trip is designed for BEB wireless charging at Walnut Creek BART. Diesel buses don't need this charging time but must wait anyway.

427 diesel trips

Hours wasted (365 days)

16678 diesel trips

Potential impact: If diesel buses could run without the 17-minute charging dwell, the wasted time from the past year could have provided approximately 6163 additional one-way trips.

Route 4 Round Trip Times: Before vs After Route Change

County Connection changed the Route 4 path on March 29, 2026. Scheduled round trip: 23 min (before) → 25 min (after). Dashed vertical lines show the scheduled round-trip time for each period.

Methodology: Round trip time is measured using GPS tracking data from the 511.org API. We define a geographic polygon around the Walnut Creek BART bus area, then measure the elapsed time from when a bus departs (leaves the polygon) to when it returns (re-enters the polygon) on the same day. Trips shorter than 10 minutes or longer than 90 minutes are excluded as outliers.
