W train service is suspended in both directions Wednesday morning as MTA crews worked on “urgent” track maintenance, the transit agency said.

The track maintenance is being done near the Lexington Av/59 St. stop, according to the MTA.

Straphangers are being encouraged to N, Q or R lines while construction work is being completed — although all three lines are currently running with delays, the MTA said.

Meanwhile, northbound 2 and 3 trains are also delayed while NYPD responds to someone being disruptive on a train at 135 St.

Southbound 2‌ trains are running express from E 180 St to 3 Av-149 St while the transit agency addresses a signal problem near 174 St, the MTA said.

And finally, southbound 5 trains are running with delays while they share tracks with rerouted trains.
