Marvel’s Spider-Man: Miles Morales has many side missions that allow players to get a break from the game’s main campaign and explore New York. These missions give a ton of rewards, new suits, and quite a bit of lore. In the Harlem trains out of service mission, you meet Uncle Davis, aka the Prowler.
Towards the end of the mission, you need to line up the trains to get them running again. This is one of the first puzzles in the game, so it can be tricky for some players out there. To line up the trains, you need to use the turntable to align them properly.
Firstly, use L1 and R1 to align the turntable along the tracks with the first train cart on it. Go back towards the start of the tunnel and pull the train towards yourself using L1 and R1 again to place it at the beginning of the tunnel. Rotate the turntable again, and this time, align it towards the track on the right. There is another train cart there; pull it onto the turntable, and rotate it to align it with the first train cart.
Finally, the last train cart is hanging just above. Use L1 and R1 to pull it down, and then rapidly press R1 to jam the gears and place it in position. Once that’s done, head back to the start of the tunnel, and Venom punch the generator to power it up. Finally, connect it to the relay nearby by shooting webs on both of them, and the subway will start running.
