Here we see four different subway services-(B)(D)(N)(Q) crossing one another on the Manhattan Bridge between Brooklyn & Manhattan.
- Rolling stocks consist of: R46/R68/A's/R160
Just to note, unfortunately only 2 R160's were captured in this video considering that this fleet as some what depleted from (N)&(Q) lines to the Queens Blvd Line due to CBTC.

From a personal stand point, this particular bridge takes on alot of pressure from both trains & vehicular traffic. Enjoy the train rumbles.
