What voltage are BART trains?
What voltage are BART trains? Third-rail power is about 80% of all power that BART consumes. Traction power engineers deal with voltages up to 34,500 volts alternating current, and 1000 volts direct current at up to 10,000 amperes.
What energy source does BART use?
BART trains are 100% electric, with over 97% of that power coming from zero and low-carbon sources including solar and hydro energy.
What happens to old BART trains?
The majority of the old cars will be recycled. The Fleet Disposition Team will manage the process, including selecting which parts should be harvested from retired vehicles and choosing which cars with the highest failure rates get retired first.
Why are BART trains so loud?
Like most trains, BART wheels are tied together with rigid axels and no differentials. This means the wheels always rotate at the same speed, even around corners. Because the inner radius is smaller, there is less distance to travel, which can cause a slippage between the wheels and track, which is noisy.
How much electricity do electric trains use?
The data in the NTD 2011 demonstrated an average energy consumption of 13.57 kWh/V ·mi (8.48 kWh/V · km).
How much power does BART use?
BART is one of the largest consumers of electric power in Northern California, using about 370,000 megawatt hours (MWh) of electricity annually, which is on scale with a small city's annual consumption.
Why isn t BART 24 hours?
Q: Why doesn't BART run 24/7 or at least later on Friday and Saturday nights? A: The short window of time when BART isn't in operation is used for essential nightly track maintenance to help keep BART safe and reliable.
Do BART trains have power outlets?
BART's new and upgraded train cars, which they've dubbed the Fleet of the Future, don't include a feature found near some seats on their older cars: outlets.
What is the top speed of a BART train?
BART has 8 DMU train cars which each have a seating capacity of 104. 70 mph maximum; 35 mph average, including 20-second station stops. For BART to Antioch DMU trains, the maximum speed is 75 mph; 60 mph average.
How often is BART cleaned?
They occur every 450 hours a car is in service. If a car is not scheduled for a thorough clean on a given night, it will get a standard clean. Depending on time constraints, cleaners may sweep cars for debris, disinfect seats and poles, scrub graffiti, spray hanging straps with disinfectant, and mop the floor.
Is BART making money?
Factoring in these new state budget funds, assuming MTC commissioners adopt the staff recommendation in mid-November 2023, BART must now solve a $326M deficit before FY28. It was previously $678M. BART would then face and annual operating deficit of $264M starting in FY28.
How much horsepower does a BART train have?
The operator cab windshield is a high-impact glass similar to that used on commercial aircraft. Propulsion is provided by four 150-HP, air-cooled, electric traction motors - one per axle.
Are the new BART trains quieter?
Testing has shown a drop of as many as 20 decibels in sound intensity. One way to think about the difference is if the decibel level of riding on a BART train with the old wheel profile and rail sounded like standing near a lawnmower the new system is more like being next to a dishwasher.
Are the new BART trains faster?
Q9: Will the new cars be faster? A: No. The new cars have a maximum speed of 80 miles per hour. To go faster than that, changes would need to be made, not only to the rail car propulsion systems, but also to other BART infrastructure.
Do trains run on AC or DC?
DC motors are used on trains is because of their high torque and good speed control. Compared to AC motors, DC motors can provide industry applications with a fine balance of strong starting torque and controllable speed for seamless yet precise performance.
What kind of trains does BART use?
The BART to Antioch extension DMU trains run on standard gauge rail. BART has 669 legacy revenue vehicles comprised of 59 A2 cars, 389 B2 cars, 150 C1 cars and 80 C2 cars in the fleet. Car seating capacity - 72 in both the Rohr-built A- and B-Cars, and 64 in C-Cars and C2-Cars.
