## B15 Service Upgraded from 24 September

The Área Metropolitana de Barcelona (AMB) has upgraded the B15 urban bus service in Santa Coloma de Gramenet, with increased frequencies and new vehicles introduced from Thursday 24 September. Under the changes, the B15 bus will now run every 12 minutes from 7am to 9pm on weekdays (excluding August), a reduction of three minutes from the previous interval. On Saturdays and during August weekdays, the service will run every 15 minutes. The improvement is made possible by the addition of six new accessible microbuses, which renew the fleet and enhance comfort for passengers, including those with reduced mobility.

## Full Route Coverage and Market Links Maintained

The B15 continues to connect key neighbourhoods across Santa Coloma, running between Les Oliveres and Montigalà, serving nearly all districts in the municipality. The line retains its existing route and supplementary services for local markets: additional itineraries operate on working Thursdays in the Singuerlín neighbourhood and on working Saturdays in El Fondo.

> “We maintain constant coordination with the AMB and the operator to monitor service and incidents, leading to improvements like today’s for the B15,”

, Mireia González, Mayor of Santa Coloma de Gramenet

> “Actions like this reflect the AMB’s commitment to improving metropolitan bus services, making public transport more connected, accessible and sustainable,”

, Carlos Cordón, Vice President for Mobility, Transport and Sustainability at the AMB

## Wider Metropolitan Upgrades Underway

The B15 upgrade forms part of a broader AMB strategy to strengthen public transport across the metropolitan area. Similar improvements are being rolled out in other municipalities, including Viladecans, as part of ongoing efforts to enhance connectivity and service reliability. Further details on the B15 service and other AMB transport initiatives are available via the [official AMB mobility website](https://www.amb.cat/es/web/mobilitat/actualitat/noticies/detall/-/noticia/mes-bus-metropolita-i-mes-connexions/31622565/11704?ref=barna.news).
