The only way out of Whittier is through a shared railway tunnel. They stagger the openings for vehicle and rail traffic, but it's pretty simple, just don't ride into the railtrack. There really isn't much to see in Whittier, although the Ferry ride should be spectacular if the weather stays nice.
Glad you are enjoying the trip.

To paraphrase Antoine de St-Exupery
I ride because it releases my mind from the tyranny of petty things.
