Hcsader CW is correct after i saw your 2nd picture of wiring.
If you want to see if motor spins as it should counter clockwise it is easier to put back on track activate whistle and observe from the top which way the armature is spinning. If whistle button is near you to otherwise just apply 12 volts to track and push up on relay plate using toothpick or with finger gently push down on the little tab located on the bottom in the back of the relay it will then activate.
Also i believe CW is correct and since wires are correct its probably still leaking air.
