Facing south, the rail crossing is not acting as it should, clearly:

Not reacting to a power source directly next to it like the redstone block or redstone torch. It is, however, reacting to one if the torch is placed next to the first redstone torch, and stays reacting when deleting the torch after placing it again. (Nothing below the crossing of course)

-Edit: I placed the blocks etc in the order the pictures come up (for me). If there is a confusion with the order, their names are dated on the second (as they were screenshots).
