J and M weekends: mid-October to late November

MTA officials warned that J and M trains will be disrupted over five weekends between the middle of October and late November 2026 while crews replace aging switches, amNY reports. The affected tracks run elevated through Brooklyn and Queens. If you are staying near those lines or using them for weekend plans, add 20-30 minutes and check the MTA app or station posters for the specific weekend pattern. These are service changes, not a full system shutdown, but a diverted or slower J or M can eat into a morning.
