Well, Cubsfrea came the closest. The wye track is the most common method. It's a triangular track with three switches. Now this is for turning locomotives since the entire train would be too long. Say you drew a triangle on a piece of paper with one side of the paper marked as east, and the other side as west. The leading end or cab end of the locomotive enters the wye from the east, Then goes to the second switch, then to the third switch on the west, now the locomotive is facing the opposite direction.
To remove grit or sand that may be under the shells, you'll need a pot big enough to hold the mussels. Dissolve about 1/4 cup salt in 2 cups warm water and then add 2 tablespoons cornmeal or flour. Add the mussels and enough cold water to cover them. Soak for 2 hours or overnight in the refrigerator. The mussels will actually take in the grain and expel the grit or sand.
Step 3: Check for Dead Ones. Mussels, clams, and other bivalves tend to gape open when they're dead, but not all gaping mussels are dead yet. Some of them are just relaxing (or perhaps stressing, if it's possible for bivalves to do such a thing).tep 1: Rinse and Scrub as Necessary. Place your mussels in a colander or bowl in the sink and run them under cold water. Rinse them to get rid of any debris or seaweed on their outer shells. If you feel any muddy spots, rub them off under the water, but you're very unlikely to with farm-raised mussels.
