It's pretty rare for tagged-up subway trains to make it out of the rail yards, but sometimes they do slip through. This morning, a 4 train that emerged at the Woodlawn stop in Bronx was covered in graffiti.

Reader Jose Donneys spotted the trains after 8 a.m., noting, "NYPD and MTA seemed pretty pissed about it!" He adds that subway was returned to the yards immediately and it took about 10 minutes for a new (non-tagged) train to arrive.

While it's unclear who is behind the tagging, most graffiti on subways is made by Europeans. Our in-house expert, Jake Dobkin, explained earlier this year, "Europeans do love to come to NYC and try to get up on a train. Most New York writers don't, because they know how quickly the trains will get buffed."
