Test Train

I was getting on the F train the other day and observed what I thought to be a test train. I was at Kings Hwy, and in the middle track was a 7 train consist. I noticed a wire that went out one of the windows and went below the body of the car.

Anybody know what it was about?

Thanks

what kind of stock was it?

Maybe it was an former revenue now work service car R33/36 combo

Nah, it was definetly a current "7" train. Some of the cars had that History Channel stripping that some of them have. I have viewed it a few more times since my orginal post.

oh, the R62A's.
they were probably doing some diagnostic testing...
