New Features

BART’s new train cars will feature a slew of new improvements. The cars will be:

  • Quieter:  micro-plug doors will help seal out noise
  • Cooler:  cooling systems will distribute air directly to the ceilings, making it more comfortable for standees on hot days
  • Comfortable:  padded seats will have lumbar support – and will be covered with wipeable fabric for ease of cleaning
  • Easy to use:  routes will be color coded like the BART system map, and next stop information will be readily available via automated announcements and digital screens.

 

General Interior View

 

Train Interior Layout

Based on customer feedback, the train interior layout is designed to maximize seating, openness, and comfort within the available space.

The new train design provides more handholds for shorter and mobility-impaired individuals. For taller customers, the design features a higher ceiling over the middle aisles, about four inches higher than the current BART train cars. The ceiling will be accented with indirect light.

The new train car design includes two types of seating areas to meet the diverse needs of BART customers. The train cars will have conventional seating at the ends that customers settling in for a longer trip may want to choose, while open seating areas near the doors may be preferred by riders traveling in groups. Riders with luggage, strollers or other personal items, as well as customers who want a little more legroom may also prefer the open seating areas.

As ridership grows, finding a seat on peak period trains is becoming harder. The new cars have as many seats as can fit within the available space. Having thinner seat backs will help maximize seat count, but new buffer zones for crash safety at the ends of the car, and an extra door in the middle, are limiting factors.

As a result, seat count will drop by 4.6 seats per car on average. To increase the number of seats in the fleet, BART has set a goal to obtain funding to increase the fleet to 1,000 train cars. This would increase the number of seats in the fleet by about 37.6%.

Handholds

For customers who have limited mobility or have difficulty reaching the high overhead grab bars, Bombardier has incorporated a multi-branch floor-to-ceiling pole near each doorway. The pole, which was popular with most customers during the train car model event at MacArthur station, will be offset four inches away from the wheelchair area to provide wider pathways for wheelchair users.

Seats

During initial customer feedback sessions, riders indicated cleanliness is a top priority. BART is currently replacing seat covers on the existing train cars with a non-porous, wipeable seat material that is easy to keep clean. This type of seat material has received a positive response among riders, so will continue to be used in the new train cars.

In addition, the new seats are almost 50% lighter than the current seats, which will save energy over the life of the vehicle. The new seats are fully modular, allowing for seat reconfiguration which will enable the vehicle to evolve with future rider needs. The seats use longer lasting silicone cushions that will improve life cycle sustainability. Also, the seats provide one-inch more legroom than the seats on the old trains.

Feedback from over 2,000 customers helped BART determine optimal seat dimensions for the new train cars. BART surveyed a random sample of BART riders to learn what dimensions were acceptable:

Based on feedback from the seat labs, the seats in the new train cars will have these dimensions:

Having the seats mounted higher off the floor will make it easier for customers to stand up from a seated position. Also it will add extra room underneath the seats to fit carry-on sized luggage. Read more about the seat lab results.

Over 2,500 customer tested out prototype seats in October and November 2013. The seats with a medium density seat bottom foam won out over high and low density options. Overall customer acceptance of the prototype seats was fairly high, and the seats got especially good ratings for lumbar support.

Bike Racks

Because BART trains are constantly coupled and uncoupled between runs throughout the day it is not possible to keep a dedicated "bike car" in a predictable position on each train. So instead, the current design incorporates bike racks in every car. The rack will be designed to stabilize bikes as the train moves.

Customers have raised concerns about the interaction of the bike rack with adjacent flip down seats. As a result, the flip down seats will be removed. Each bike rack has enough slots to hold up to 3 bikes.

 

Passenger Information Systems

The new cars will include six interior digital LCD screens, one next to each door, that will display the system map, next stop and transfer information, as well as travel advisories and other announcements.

Please email BART with your feedback.

 

The new train cars will also have LED screens on the ends of the cars that will display next stop information. Additional digital screens on the exterior of the cars will display route color, the train’s destination, and possibly other information.

In addition to the digital screens, many hearing-impaired riders may benefit from an induction loop system that transmits information directly to receptive hearing aids and cochlear implants. This is a feature that the Bombardier engineers are planning to develop and test.

Sight impaired passengers will benefit from automated audio announcements and a better quality PA system with interior and exterior speakers.

Doors

In anticipation of dramatic ridership growth over the next 30 years, the new train cars will have three doors on each side to make it faster and easier for passengers to get on and off trains. Two of the doors will be located in the same place as today. A third door will be located in the middle of the car.

As the new train cars are delivered over the course of a decade, BART will be running a “mixed-fleet” of new and old cars. The black tiles we have today on the platform to mark where the doors open will remain useful to demarcate the doors for both old and new trains. BART will be evaluating whether any additional markers are needed to demarcate the location of the middle doors.

micro plug doors

 

The doors on the new trains will use an entirely different technology than that used by the current trains. Currently, BART trains have pocket doors that slide into the wall when they open. These doors contribute to a noisy ride on BART because they do not adequately block out noise from outside the train and they can rattle as the train travels through tunnels.

The new doors will utilize micro-plug door technology. This means they will slide on a track outside the train, similar to a mini-van door. As they slide closed, they will pull in ¾ of an inch to seal tightly around the door frame. This “plug” will dampen the amount of noise that reaches the inside of the train, as well as providing better thermal insulation, making the cars more comfortable on very hot or cold days.
