Train-ing the young

Bayside’s Lenny Grasso shares a mass transit moment with grandson Sebastian, 3, as he explains the train signal lights from the 221st Street overpass of the Long Island Rail Road. “He loves the trains - we come here all the time.” Grasso said. At 30 pounds, Sebastian “isn’t much of a load,” grandpa says, “but if he gets much bigger, we’ll have to bring a chair for him to stand on.”
