    Media coverage about turnbacks never goes deep enough, stopping with where and who’s complaining.

    Paul Rose at SFMTA, at least in the quoted portions, explains how Muni is trying to deal with it, but still not going down into why the addition of JKLMN trains tricking up passengers is helping.

    Much of what’s causing the bunching and need for turnbacks – and where a big share of derailment and switching problems happen – is the Fourth and King intersection, where the T-line is temporarily making a turn to merge from the Third Street Corridor onto the Embarcadero.

    When completed, the T-Third Street line will cross the intersection north-south, the N-Judah will cross east-west, and without having to turn both Muni and car traffic can share the same phases. That’s also when the complete different station platform designs will start making sense: N-Judah stops will have the curvy roves, T-Third stops have the angly ones and the bright green poles.

    Until then, there is an extra turn phase every single time a T-Third street train turns, from third street alignment onto the Embarcadero alignment. They often come in quick succession when inbound and outbound trains around almost at the same time, but not close they can share the same turn phase. Every time a T-line train gets caught waiting behind an N-Judah is another delay. And because the inbound T-line track crosses over the outbound N-line track, that’s an additional chance of delay for both lines in all directions.

    Had it not been for the delays, the Central Subway would be open – or nearly so – and this problem would largely sort itself out.

    Something else that would really help that a lot of readers here would like yo se happen is to remove the traffic inducing freeway on/off ramp that touches down just about at Fourth and King.

    “Had it not been for the delays, the Central Subway would be open – or nearly so – and this problem would largely sort itself out.”

    Which delays?

  • SteveS

    Fourth and King is undoubtedly the worst offender, but Muni still has to fix signal priority on the entire line if it’s ever to become anywhere near as efficient as the bus service it replaced.

  • mikesonn

    100% agree

  • Does anybody know the status of signal priority near 4th and king? It is maddening to sit at the light waiting for all the cars while Caltrain departure time approaches

  • Jamison Wieser

    As you very well know, the Third Street Light Rail Project is much different today that first conceived about two decades ago and the Subway portion went through a major redesign well into construction of the surface phase.

    Current status: cars >>>>> transit

  • mikesonn

    Either way, that turn was planned for (and not as a short stopgap) so it shouldn’t be the complete fail that it is.

    So the reason why Muni’s utterly insane and inefficient and actively dangerous (4th/King is nothing but dangerous, and isn’t going to change, ever) and slow and costly “light” rail cluterfuck is .. to piss away another TWO BILLION public dollars building a subway line that nobody will ride but will handsomely reward the engineering/construction mafiosi?

    That’s a simply marvellous solution to “a big share of derailments” … especially when the intersection and trackwork and service “plan” in question was “designed” and “implemented” by exactly the same cast of rent-seeking hanger-on consultant failures and worthless negative-achievement agency lifers who are behind the guaranteed-to-crater Central Subway.

    The solution to being in over your head in a collapsing hole is … to keep digging.

    CHUG THE KOOL-AID! Mmmmmmm.

    Oh come off it Jamison. Shut up and be grateful that the MTA lets us prols have any trains at all. From the BG:

    Rose explained in an email. “These trains are J, K, L, M, and N trains that travel in service as T-Third trains to the yard and accept passengers all the way to the last stop before the yard – 23rd Street. The alternative is to have the trains travel ‘not in service’ to the yard from the subway and accept no passengers.”
