Maybe the Brooklyn leg of the could be rerouted to Broadway and run with the to Times Square or 57 St-7 Av Depending on how much track is available. This way you don’t clog up 4 Av in Brooklyn. trains would be rerouted back to Broadway And run only to Times Sq-42 St (assuming 57 St-7 Av cannot be used to turn trains around). if necessary, reroute some trains via the line between Atlantic Av Barclays Center and Canal St 0 Quote Link to comment Share on other sites More sharing options...

When stuff like this happens, consistency is already thrown out the window. No matter how hard you try to get trains to keep a even spacing, it's just not possible. You sometimes just have to squeeze trains in wherever possible in order to not delay other trains behind you. Under what I posted, there wouldn't be any trains on 6th Avenue. You still need trains to run in Queens as well, hence why some are terminating at Court Square and heading back. Also, having all and trains terminating at Court Square together can cause congestion issues. If there's a scenario where an from the north and a from the south are both a stop away from Court Square (and there's already another train on the other track), it's best to send the down Crosstown since it'll cause less delays, especially since the isn't anywhere close to the incident location. This is why some trains are also going down Broadway. There are times where trains are laid up at the lower level of Canal on the weekend, and this is assuming that it isn't possible (and the middle track is unusable). As for the vs. scenario, it's more or less damage control. You can't have the carrying everything and running all local into upper Manhattan and Brooklyn with no , and you can't just leave 2nd Avenue without anything (and have everyone go to Lexington Ave). You could potentially have trains running approximately every 12 minutes just to reduce the tph in that segment and potential conflicts, but they'll still exist. 1 Quote Link to comment Share on other sites More sharing options...

BM5 via Woodhaven Posted June 1, 2020 Share #6310 Posted June 1, 2020 I'm going to try a variant of my previous scenario: It is a Saturday, 4:15 PM. Assume this takes place after the COVID-19 pandemic (so use regular service levels). The 8th Avenue Line is shut down from south of 59th Street to West 4th Street in both directions for necessary track work. In addition, there is signal work being done on the 60th Street tubes, so trains going from Broadway to Queens Boulevard are operating via 63rd Street instead for the weekend. An issue arises where there is a broken rail on the SB local track at West 4th Street. Reroute all trains which will be affected by this disruption, using the current weekend service pattern. Complete suspensions of any line are not acceptable, but partial suspensions if needed can be done. However, if any partial suspensions are done, have a plan for what will happen for affected trains that are currently operating within that suspended section. It might help to first make necessary reroutes based on the signal work and track work that I mentioned, and then reroute trains based on incident at 7th Avenue. A max constraint of 16 tph is allowed on any individual QBL track and 6th Avenue track, with the exception of the SB express track on the 6th Avenue line south of 34th Street, For reference: - 6 tph - 5 tph - 5 tph - 5 tph - 5 tph - 6 tph - 6 tph - 5 tph 0 Quote Link to comment Share on other sites More sharing options...

B61In2002 Posted June 5, 2020 Share #6319 Posted June 5, 2020 Ok at first I thought this was simple but its not, so I'm gonna go with the 2 ways I see service going. (Please note: you never said 72, 86, 96 were in service.) Option 1: service stays the same, 96 - Coney Island. trains still take over 6 Av Lcl, and run between 21 St - QB and Metropolitan Av. trains run 179 - Coney Island via 53rd. stays the same, and trains run between Forest Hills and Church Av. Option 2: Post MannyB repairs and post SAS, service on the letter lines look like this: 207 - Far Rockaway or Lefferts Blvd, CPW Lcl late nights Coney Island - 21 St QB via West End & 6th Av Exp, all times. Brighton Beach - 205 St. CPW Lcl, late nights 2 Av - 205 via CPW Exp. 168 - Euclid. Peak rush hour service to/from 205 St. Weekends 205 - Euclid. No service late nights. Coney Island - 96 St via Brighton & Broadway. Coney Island - Dimtars Blvd. Select PM rush hour trains to 21 St - QB or 96 St. Late nights via tunnel. 95 Street - Forest Hills. Late night service Whitehall - 95. service between Dimtars - Whitehall. Rush hour service to 86 St or Bay Pkwy . No weekend or late night service. Option 3: becomes 6 Av Lcl between 21 St - QB and LES - 2 Av. If low ridership, becomes . runs 71 Av - Church Av full time. Now, I'm gonna take inspiration from the person with the Q99 profile pic, and create my own monstrosity. : The portal between Grant Av and 80 St collapsed. : the switches at Prospect Park and Kings Hwy have jammed, so the local track can only be operated by the . : In The Bronx, a work train ran out of power north of 149 St (upper level) blocking the switches there. South of 149 St, a SB train has slammed its emergency brakes on, blocking the center and SB tracks. (Track work at 138 St required trains to run on the center track between 149 and 125. : a train derailed at City Hall. : the switch is jammed at Main St. All trains exiting the station from the WB track automatically are switched to the center track. Furthermore, a work train is stuck at 111 St trying to enter the yard, blocking the EB track. : a SB has derailed just before the 36 St station, blocking both SB tracks. The relay track is still available. :There is track work being done on the Williamsburg Bridge, and a truck has rammed into a pillar at Myrtle Av-Broadway. : a NB train has stalled on the junction outside 36 St trying to go from the express to local track. Track work is being done on the SB side with the Junction that connects the to West End. : 2 Church Av bound trains rammed into each other at Classon Av. The uptown tracks on the 6th Av Line are under repairs between Rockefeller Center and W 4 St. (The junctions are still available.) The downtown tracks on the Broadway Line south of 57 St and north of Canal St (upper level) are also under repair. You can only run so many trains on 8th Av, so improvise! 0 Quote Link to comment Share on other sites More sharing options...

I'll ignore the foaming but respond as to why this would not work: For this to work, not only would the have to share the tracks with the on Central Park West, but with the between Columbus Circle and 42nd Street, and then with the to Downtown. All of this switching would cause delays on the , plus delays on the due to the being delayed. Terminating it at 57th Street would cause less delays than your ridiculous solution. And I didn't even talk about how illogical and moronic it would be to send the to somewhere where it clearly shouldn't be. Doing so would make its route longer than it currently is when it goes to Queens, which would require you to either add additional trains or increase headways.

A northbound train has derailed at the Dekalb Interlocking, blocking all northbound tracks (except the Montague St tunnel) A got stuck on the switch diverging the southbound track to Borough Hall & the Inner Loop track, and a train has stalled on the Outer Loop South Ferry station. The train derailed at 3 Av - 149 St, blocking both tracks. A 5 year old decided to play with the emergency breaks, and now the SB train stalled on the switch between the local and express tracks between Franklin and Nostrand Av. A randomly rerouted northbound stalls on the switch outside Columbus Circle. The derails at Brodway Junction. A stalled blocks the merger between the Canarsie and Jamaica lines. The is blocking BOTH northbound local tracks at West 4th St. Reroute away! (I'd LOVE to see your awnsers to these ones. Also, keep in mind the era, this was pre Chyrstie St connection but post Loop Service. 0 Quote Link to comment Share on other sites More sharing options...
