This long Christmas weekend, from 10:45 PM Friday, December 21 to 5:00 AM Tuesday, December 26, there will be no 2 and 3 train service (meaning no service at Clark Street or on the 2/3 platforms at Borough Hall), which will be a fact of life every weekend until sometime next summer. As usual, during the absence of 2/3 service, 4 and 5 (5 trains don’t usually serve Brooklyn on weekends) will provide alternate service to and into Brooklyn. Apart from that, there are no planned cancellations, route diversions, or station skips directly affecting service at any local stations during the holiday weekend nor during the following work week: Tuesday, December 26 to Friday, December 29.
For planned service changes that may affect travel on other parts of the system, either during the weekend or the following week, and for unplanned disruptions, see MTA Info.
