BART also has a new fleet of 775 train cars being incorporated into service with improved digital screens and dynamic system mapping, more doors, and new wheels to reduce noise by 50%. There are also station modernization programs and multiple TOD projects being built and proposed on BART-owned property adjacent to the stations. So far, over 4000 units have been completed with another 2000 more in the pipeline. BART extension to SJ has been slow, but I'm not sure how that's different than any other transit extensions currently underway in the US. Then we've also got the Muni Central Subway extension and the new Van Ness BRT line. Obviously there could be a lot more done. A second Transbay Tube, a Geary subway line either BART or Muni, a Dumbarton rail crossing, and completed HSR are all on the bucket list, but that's obviously limited by the amount of funding is received and our nation's miserly attitude towards transit investment, not a Bay Area specific fault. |
SF will gain a lot from the opening of the Central Subway and Caltrain electrification.

The Expo Line only runs in mixed traffic between DT LA and USC, a distance of 1-2 miles, on trackwork shared in part with the above-mentioned Blue Line. There has been a lot of chatter regarding improvements to this section. The Green Line is pretty much the only light rail in the United States that is completely grade-separated. |

If BART has 15 min. headways, that's pretty impressive for U.S. standards.
BART is functionally a commuter rail line. Living somewhere like Hayward and having a train every 15 min. to Oakland or SF is pretty good. Washington Metro is more of a hybrid subway/commuter rail line, so should have somewhat shorter headways. |

^ there's often bound to be a few places on most systems where an at-grade street crossing or two occur.
hell, even on chicago's heavy rail el system, 4 of the lines (purple, yellow, brown, and pink) have some at-grade street crossing at their extremities. in fact, i live right at the spot where the brown line transitions from steel elevated structure to running at grade. my local el stop is one of the unusual at-grade ones right at an at-grade street crossing. https://www.chicago-l.org/stations/i...rockwell12.jpg source: https://www.chicago-l.org/stations/rockwell.html and i grew up in suburban wilmette a couple blocks away from an at-grade street crossing at the very end of the purple line. i guess i just have a thing for that sort of thing. i wonder if any of the other heavy rail rapid transit system in the US have any at-grade street crossings? |

I'll give credit for the Regional Connector, but Crenshaw Line construction is a disaster. Crenshaw began construction in 2014, is only 8.5 miles long, and has a street running section/grade crossings. San Diego's Mid Coast Trolley broke ground a full two years later, is 11 miles long, is fully grade separated, and opened on time and on budget in November. Meanwhile, Crenshaw is still under construction and over budget. |

15 minutes both directions is great for a hybrid rapid transit/commuter rail, S-Bahn type of system. It is a one-of-a-kind system in North America, not comparable to anything else.

2000 residential TOD units in the pipeline for a system with as much ridership as BART isn't a lot. And how much of the TOD is office space? Office TOD generates more ridership than residential TOD. But with big corporations moving out, not moving to, the Bay Area, I doubt there'll be lots of office TOD popping up near BART stations soon. San Diego Trolley has very little TOD outside of Downtown currently. But they have a whopping 10,000 residential TOD units and 2.6 million sq ft office space approved or under construction on the Green Line alone, and that's not counting downtown Projects. That's astonishing for a smaller, slower growing metro area. |

https://cs.trains.com/trn/f/742/t/156685.aspx The LIRR definitely has third rail crossings, but it's not rapid transit. |

Muni Metro (light rail) also has new trains, 68 of which are currently in service, with another 181 incoming in the next 3 years for a total of 249 new train cars. Muni buses are already quite new with their biodiesel-electric hybrid buses (all built 2013-newer with most being built 2015-on) and New Flyer Industries electric trolley (all 2015-newer), and they're testing a small fleet of battery-electric buses to see if it is viable to have an all-electric bus fleet by 2035. As for office TOD, so far over 500,000 sq ft has been completed, with another 2.04 million sq ft in the pipeline. |

Yes, bus and light rail lines frequently have 15 minute or better frequencies, even in moderate density corridors. |
Quote:
If you take a train from Penn Station to Babylon, or a train from Grand Central to North White Plains, you'll never have a crossing. In fact for most of the main lines, you're never at grade. You're on an elevated structure, an embankment or a trench. In the postwar decades, they converted the busiest lines to rapid transit-level infrastructure. |

From the rider's perspective, smaller, more frequent trains offer more convenience than bigger, less frequent trains. |
The term frequent means different things in different contexts. From the rider's perspective, it's also about the speed of the route and distance covered. I'd be fine waiting 15 minutes for a fast train to go 30 miles across the metro area but I'd rather just walk than wait 15 minutes for a service to go 1 mile within the nabe. In other words, I'd consider the 15 min service frequent in one case and infrequent in another. That has nothing to do with whether it's light or heavy rail though.
