NEW YORK (CBSNewYork) — There is a big sign of progress on the Second Avenue Subway – trains are actually running on the line now.

But you can’t ride them yet.

As WCBS 880’s Alex Silverman reported, the Metropolitan Transportation Authority said the Second Avenue subway – which will be used for a new route for the Q Train – is still on track to open on New Year’s Eve.

Many are likely to say they will believe it when they see it, but now, there is something to see.

A spokesman confirmed that trains are now running on the line as a test, and they are visible from the stairway at the 63rd Street and Lexington Avenue transfer point.

Transit enthusiast DJ Hammers posted video of the test to YouTube over the weekend.

The trains have weights in the cars, apparently to simulate the weight of some of the passengers.
