Caltrain’s oversized bicycle policy proposal

Caltrain is considering a rule that would ban oversized bicycles longer than six feet and with tires wider than three inches. They say it’s an attempt to address rider complaints about space and maneuverability inside train cars.

The agency reports seeing about 7,600 bicyclists on board each weekday. Ridership in February jumped by 30.4% compared to last year.

Officials point out that large e-bikes and cargo bikes take up more space. This makes it tougher for people to get through seats, aisles, and doors, especially during rush hour in Marin towns like San Rafael, Novato, and Larkspur.

Caltrain says bulky bikes and extra accessories can block aisles and make it harder to reach seats and exits. Riders with compact bikes might find this helpful, but critics—especially parents riding with kids on modified bikes—worry the rule would disrupt their routines and single out certain groups.

Caltrain keeps saying this is a discussion starter, not a done deal. They want feedback from the public and the Bicycle and Active Transportation Advisory Committee (BATAC) before making any decisions.

On the operations side, Caltrain offers about 500 bike lockers at its stations. That helps some folks, but it’s not enough for everyone in Marin.

For commuters in places like Tiburon, Corte Madera, San Anselmo, and Fairfax, lockers just don’t work for multi-day trips or families hauling gear. Many Marin County riders, especially those biking to San Rafael or Mill Valley as part of a longer trip, can’t just drive or stash a second bike at home—it’s expensive or they just don’t have the space.

Public input and listening sessions

Caltrain’s public information officer, Dan Lieberman, says the agency wants a real conversation with the bike community before changing anything. They’re hoping to get practical feedback from riders who rely on bikes to reach Caltrain stations in Marin and beyond, from Novato to Sausalito, where a lot of people connect to ferries or buses.

They’re calling this a starter discussion—not a final rule—and want input from BATAC and the public.

The Bicycle and Active Transportation Advisory Committee (BATAC) is holding a public meeting on March 19 at 5:45 p.m. in San Carlos. There’s an option to join virtually or send in comments ahead of time.

Marin residents who ride to stations in San Rafael, Novato, or Larkspur might want to show up and share what it’s like dealing with crowded trains, stairs, and station access—especially with kids or bulky bikes in tow.

Caltrain says they’ll weigh BATAC’s recommendations and public input as they work out the policy details. For Marin County families and commuters who depend on bikes to reach Larkspur Landing, the headlands near Mill Valley, or ferries from Sausalito, it’s a tricky balance between safety, efficiency, and accessibility on packed trains.

How Marin riders can weigh in and what to expect

With the March meeting coming up, Marin cyclists have a few things to think about. Here’s how they can get involved:

Identify your use case—Are you riding a cargo bike, a big e-bike, or just your usual commuter? Think about how often you actually need more space on trains connecting Marin towns like San Anselmo or Novato.
Assess station access—Picture your routine to get to San Rafael or Larkspur stations. Would lockers or some other storage option make your life easier?
Share safety concerns—Notice any trouble getting around crowded train cars, tricky doorways, or exits? This hits especially hard for families with kids in places like Corte Madera and Fairfax.
Suggest practical alternatives—Got ideas for dedicated bike spots, better signage, or maybe more flexible size rules that still keep everyone safe? Toss them into the mix.
Provide location-specific context—How would these changes hit riders in coastal or hillside Marin, from Pacifica to Greenbrae? What about those traveling the 4th and 5th corridors near the 101?

If you ride anywhere from Mill Valley to Novato, keep an eye on BATAC updates. Consider sending in your thoughts before the March 19 meeting.

Caltrain wants to hear from people who rely on trains, bikes, buses, and ferries to get around Marin’s beautiful but often packed commute routes. It’s your chance to help shape what comes next.
