Instead of waiting in traffic for hours, wouldn't a low stress, quick, and convenient option by train be a better solution for travel? Imagine a future with a faster, more connected train system that provides people with safe, efficient, equitable, and affordable travel whether going to work, school, to visit family, or for fun. Picture the possibilities with convenient access and improved train service to connect to desired destinations across the Northern California Megaregion. There are many different factors that make up train service and ultimately, it’s the service provided that creates the passenger experience. 

Link21 的服務改進包括:

  • Reliability:  timely departure and arrival
  • Faster travel times:  quicker arrival to  your destination
  • Frequency:  more trip options and shorter wait times
  • 便利:  更直接的出行和更便捷的換乘
  • More capacity and resiliency:  service redundancy to reduce crowding and maintain travel options during service disruptions
  • Equity:  increased train service access for communities that have been marginalized, the transit dependent, and access to important destinations
  • Longer hours:  extended service on nights and weekends (Requires policy decision/action by BART)
  • Clean and green travel: Shifting travel away from congested freeways and increasing ridership on future zero emission trains  
  • Markets and connections: better service to existing or new stations and easier connections between train services

A foundational goal of Link21 is to transform the passenger experience and one important way to do this is to improve service, one of four building blocks for Link21 concepts in addition to markets, train technology, and infrastructure. We have been engaging with residents and agency stakeholders across the Megaregion to better understand travel needs. In response to what we have heard, we have identified Link21  concepts  that are designed to add service frequency, potential new connections, travel time savings, more direct trips, and better transfers between Regional Rail and BART. A new train crossing between San Francisco and Oakland provides service redundancy and reliability by allowing trains to continue operating, should one crossing temporarily be taken out of service. A new crossing makes the existing megaregional train system function better, while also offering riders new or improved service.

所有考量中的 Link21 概念都改善了現有的服務,且每個都提供有價值的福利,創造了更好的接入、連接和可靠性。 Link21 專注於在核心灣區提供更多城市 | 地鐵服務,並改善長途乘客的城際 | 快車服務。 請詳細瞭解這兩種重要的服務類型,以滿足您的出行需求:

城市 | 地鐵


A type of service for short to medium trips that operates within metro regions at higher frequencies and medium average speeds. BART provides this service today. Caltrain will provide this type of service with its modern electrified trains starting in fall 2024.

  • 更多班次的列車(每 2-10 分鐘一班)
  • 車站之間停靠站更多/距離更短(相距 1-5 英里)
  • 中等平均速度

Intercity | Express  


一種中長途出行服務,以較低頻的車次和較高的平均速度連接地區以及城際和農村社區。 Capitol Corridor、Amtrak、San Joaquins、Altamont Corridor Express 以及其他業者在通常由私人貨運鐵路擁有的共享軌道上提供該項服務。

  • 班次較少的列車(每 30 分鐘-1 小時以上)
  • 車站之間停靠站更少/距離更長(相距 5 英里以上)
  • 更高的平均速度,縮短行程時間

Link21 is looking to enhance these service types within key corridors and better connect the standard-gauge (Regional Rail) and broad-gauge (BART) train systems. Determining which train technology will go in the crossing is based on the desired service outcomes and markets to which we wish to connect. 

Service Trade-offs

The reality about designing train service is that some service features can’t occur simultaneously. Here are just a couple examples of trade-offs the Link21 Team is considering through its planning process:


Service to many stations expands access to more areas. But since the train is starting and stopping more often, it takes longer to get where you want to go. Express service gets you to your destination faster, but has limited stops that might not fit your needs. Caltrain has both express and all-stop service. A system can have both, but not all stations have the same types of service.


We all like the idea of boarding a train once and taking it straight to our final destination (what we call a one-seat ride). However, a system that only has one-seat rides will be more limited in  providing frequent train  service  on the busiest routes.

If every station offered a one-seat ride to every destination across Northern California, segments  carrying the most routes would have more trains than they could carry. Trains on those routes wouldn’t be able to operate with enough frequency, riders would need to wait longer, and once onboard, experience more crowding.

The alternative is to design  train routes and  transfers  together so that it’s quick and easy to  change between trains on routes that run frequently. A rider’s overall travel time may be shorter because  they can catch a train that comes sooner.

We recognize transfers can be difficult for some riders so we’re exploring opportunities to improve ease of travel for riders, including seamless transfers, short walking distances, and accessible stations.



Standard-gauge (Regional Rail) train technology  can provide riders with two different types of service with one crossing: Urban | Metro and Intercity | Express service. This option creates opportunity for a better Oakland transfer station between BART and Regional Rail as well as bringing new Urban | Metro service to stations in the East Bay that do not have it today.

See examples of how standard-gauge (Regional Rail) technology in the crossing could transform and improve today’s trips:

區域鐵路 - Sacramento / Stockton

來自 Sacramento / Stockton 地區的乘客可以:

  • 可選擇直接單座乘車選項(無需換乘)前往舊金山,然後沿著 Peninsula 繼續前行(需要換乘)
  • 直接前往屋崙(奧克蘭)市中心的 BART 車站
區域鐵路 - 屋崙(奧克蘭)
  • 增加 San Francisco Peninsula 和 Richmond 之間或南至 Coliseum 站點/屋崙(奧克蘭)機場連接線之間區域鐵路軌道的城際|地鐵服務
  • 屋崙(奧克蘭)市中心區域鐵路和 BART 之間的直接換乘
  • 對 Coliseum 站點區域鐵路、BART 和屋崙(奧克蘭)機場交匯點之間的換乘體驗進行了改進
  • 服務於 Alameda 新市場
區域鐵路 - 舊金山
  • 不排除未來延伸/連接至舊金山西部鐵路線的可能性
  • 與 Sales Force 換乘中心的連接便宜您訪問其他鐵路服務,包括透過市中心鐵路延伸項目的 Caltrain,為乘客提供往返於舊金山 Peninsula / Silicon Valley 與 East Bay、Sacramento 和 Northern San Joaquin Valleys 之間更短、更便捷的出行
鐵路通道的寬軌 (BART) 列車技術

Broad-gauge (BART) train technology provides riders with more Urban | Metro service within the existing BART system and improved frequency of service on the East Bay lines. This option creates opportunity for a better Oakland transfer station at Jack London Square between BART and Regional Rail.

See examples of how broad-gauge (BART) technology providing Urban | Metro service in the new crossing could transform and improve today’s trips:

BART - Sacramento / Stockton

來自 Sacramento / Stockton 地區的乘客將在 Oakland Jack London 站點換乘 BART 前往舊金山和 Peninsula。

BART - 屋崙(奧克蘭)
  • 新 Oakland Jack London 站點的 BART 和地面區域鐵路站點,方便兩個系統之間的換乘
  • 服務於 Alameda 新市場
  • 對 Coliseum 區域鐵路站點和 Coliseum/屋崙(奧克蘭)機場連線 BART 之間的行人連接進行了改進
BART - 舊金山
  • 服務 Mission Bay / SOMA 地區的新市場
  • 將在未來 4th / Townsend 站點的 BART 和區域鐵路之間新增換乘服務
  • 不排除未來延伸/連接至舊金山西部鐵路線的可能性
