The difference: Whereas the weekend service picks up riders every 20 minutes, the weekday program will provide service every 15 minutes, SamTrans says.
With the launch of "Route ECR," SamTrans will eliminate the existing routes 390 and 391, which weren't interchangeable at some locations and ran only every 40 minutes, SamTrans spokeswoman Jayme Ackemann said.
"With the new Route ECR service, SamTrans expects to provide mainline service that is easier to understand, more reliable, more convenient and more frequent," Ms. Ackemann said. All buses will pick up riders at the same stops, "so customers won't have to worry about whether they are on the right bus," she said.
The El Camino corridor has the heaviest bus ridership — 50 percent of all riders — in San Mateo County, she said.
With the change, bus travel to San Francisco, now available on the Route 391 bus, will end. The cost savings from that move will allow SamTrans to "invest more heavily in its Peninsula service," running every bus into Palo Alto, Ms. Ackemann said. To get to San Francisco, riders will have to use Route 292, Caltrain, Muni or BART.
