Tap, tap, tap. Is this thing on? The last few weeks have been exceedingly busy, and regular updates should resume shortly. In the meantime, it’s W Train Monday.

As the Second Ave. Subway slowly crawls to an opening — not on time unless the MTA picks up the pace of testing by a considerable amount, the agency’s Independent Engineering Consultant said two weeks ago — Monday’s commute brings with it a milestone of sorts as a new old train line resumes operations between Queens and Manhattan. The endearingly kitschy signs have been hanging up in N, Q and R trains, and the signage throughout the system has been updated for the impending return of the W train.

As train rebirths go, this one could be more exciting, and the early November return for the W is a nature of the way MTA crews put in for shifts months ahead of time. Although the Second Ave. Subway may open in early 2017 instead of late 2016, the new Transit shifts start tomorrow, and any delay in restoring W service would have resulted in trains that needed to run but no crews to operate them. The W, meanwhile, comes back before the Q is rerouted to the Upper East Side to ensure Astoria has nearly the same level of service as it currently enjoys with the Q and N trains. We’ll come back to the “nearly” element shortly.

For the rail-watchers among us, MTA spokesman Kevin Ortiz tweeted out the details of the W train’s first runs on Monday:

W returns! 1st s/b trip of the day leaves Ditmars at 6:53am. 1st n/b trip leaves Whitehall St at 7:06am.

For those interested in the day-to-day operations of a subway train that hasn’t graced the rails since 2010, the details are less glamorous. The W trains will operate on weekdays only between approximately 7 a.m. and 11 p.m., making all local stops between Astoria-Ditmars Boulevard and Whitehall St. (with one or two unannounced trains operating into Brooklyn to reach the Coney Island Yards). The N will now be express in Manhattan during weekdays but with a stop at 49th St. as all Q trains make express stops along Broadway, terminating at 57th-Broadway until the Second Ave. subway opens. The R train, meanwhile, will get a nice service boost as late-night service will be extended from 36th St. in Brooklyn to Whiltehall St.

This is a whole lot of shuffling around the edges for the big moment within the next few months when the Q begins to run to 96th St. and 2nd Ave., but it will cost Astoria a few trains per day. The MTA assures me that Queens’ peak-hour service will not be reduced, but the off-peak frequency will be slightly lower. This move comes at a time when the MTA has been encouraging more off-peak ridership and is driven by the fact that W trains lay up in Manhattan or Brooklyn, a lengthy ride away from the northern terminus in Astoria.

DNAInfo’s Jeanmarie Evelly reported on the service reduction last week. The scheduling shift means approximately 20 fewer trains per day to and from Astoria:

Frequency of service during rush hours will remain the same, with N/W trains from Astoria into Manhattan running every 4.3 minutes — about 14 trains an hour, the maximum the line can handle — between 8 and 10 a.m., the same as current N/Q service.

In the evenings, N/W trains from Manhattan into Astoria will run about every 4.3 minutes between 5 and 6 p.m. and every 4.5 minutes between 6 and 7 p.m., the same as N/Q trains run now, according to the MTA. Trains will run less frequently from Astoria into Manhattan from 5 to 7 a.m. and 10 p.m. to midnight, and from Manhattan into Astoria from 6 to 8 a.m. and between 11 p.m. to midnight, the timetables show.

The MTA says it will track ridership numbers on the N/Q/W lines in the coming months and make schedule changes if needed.

This is an unfortunate reality of infrastructure decisions made over 100 years ago, but it also highlights how the MTA has often been less than honest about the nature of the service changes. The agency had repeated assuaged Astoria residents service would not be cut, but it’s clear that the area will see fewer trains (and longer waits) during off-hour periods of low ridership. How the area responds — and the limitations of the MTA’s available rolling stock — will dictate what happens next.

Meanwhile, as the W begins its resurrection ride in a few hours, the Second Ave. Subway moves ever so slowly to becoming a reality.

Despite repeated concerns from the MTA’s independent engineering consultant that the Second Ave. Subway may not open on time in December, the agency is doubling down on its commitment to launch this long-awaited line before 2016 is over. Still, a recent crosstown trip on the M86 showed me that a lot of work remains to be completed as fall heads toward winter, but with the W train’s return on the horizon, New York City is slowly and inexorably moving toward the debut of the city’s greatest urban legend.

First up, as you can see from atop this post, the MTA is priming the pump for the W train. I spotted that poster on a Q train, and many of my Twitter followers have sent in images of the W’s return. The signage describing service patterns, as you can see, remains as incomprehensible to the untrained eye as ever.

The train, which serves as a part-time Broadway local with service to Astoria was lost to the 2010 service cuts, and with the Q destined for 2nd Ave. and 96th St., the W will pick up the load. In addition to the return of the W, the R train will service Whitehall Station during the late-night hours. The new service patterns begin in two weeks as all Q trains will terminate at 57th St.-7th Ave. until the Second Ave. Subway opens.

And what of construction? No end of an MTA project would be complete without construction mishaps, the Second Ave. Subway is obliging us in that regard as well. As Dan Rivoli of the Daily News reported over the weekend, some segments of the new tunnels were too small and workers had to shave down parts of the curves in order to fit 75-foot-long subway cars. MTA officials assured the public that the work has been complete and tests continue (though it’s unclear how this engineering mishap occurred in the first place).

“There is no change to the anticipated date Second Avenue will be open. Tests are conducted as part of the overall process to get the tunnel ready and are done precisely so that we know what adjustments may be needed. Training runs are now being made regularly with 75-foot cars,” MTA spokesperson Beth DeFalco said to the News.

And finally, as the MTA comes face to face with the reality of a December opening date, the agency is willing to admit on the record what the whispers have said for a few months: The Second Ave. Subway may “open” “on time” by having trains skip the 72nd St. station. Emma Fitzsimmons, in a profile of the subway line for The Times, had more:

The authority’s credibility is on the line — not just to meet the deadline, but also to deliver a high-quality project. The city’s first new subway station in a quarter-century opened last year at Hudson Yards on the Far West Side of Manhattan. Several months later, major leaks appeared.

Mr. Prendergast has not ruled out opening the new line, but temporarily bypassing 72nd Street if that station is not yet ready. After a board meeting last month, he said trains had temporarily bypassed stations after the bombing in Chelsea on Sept. 17. Mr. Prendergast said last week that it was too early to discuss skipping stations and that he was focused on making sure they were all ready on time. “We haven’t given up on anything at this point,” he said.

For the MTA, such an arrangement would be a departure from the norm as MTA Capital Construction must certify an entire project complete for New York City Transit to begin operations. If the feds, however, are willing to permit service to some stations as crews complete 72nd St., it’s possible that the Q will make three of its four stops for the first few months. With Gov. Cuomo a driving force behind the push for a December opening date, even the culture an an institution as slow to change at the MTA could shift to permit some early subway rides to 96th St., 86th St. and 63rd St. without service to 72nd St.

The countdown continues apace.

Via the tireless Max Diamond (better known to the internet as DJ Hammers) comes proof that yes, Virginia, there is a Second Ave. Subway. The eagle-eyed videographer spotted a series of test trains running north past the 63rd St. station on Lexington, a future transfer point between the Second Avenue’s Q train and the F train. Take a peek:

The test trains are a key element in prepping the line for its eventually opening as they run to ensure proper clearances in stations and tunnels (including gaps between the train and platform, as we saw at South Ferry in 2009), a functional signal system and a power stress test, as one worker noted on Instagram. This is certainly good news for those New Yorkers, like my dad, who have long since stated that they won’t believe the Second Ave. Subway exists until they actually ride a train, but it’s not clear if this good news for the MTA’s slowly shrinking timeline. As recently as two weeks ago, the agency’s own consultants noted that the pace of testing is still lagging behind the line’s planned opening prior to the end of 2016.

For now, though, trains are starting to roll without passengers. It’s a first step toward finalizing the first segment of a subway line over 80 years in the making.
