SAN FRANCISCO (AP) — A group of mostly black women filed a racial discrimination lawsuit Thursday after they were removed from a train that tours Napa Valley wineries, saying it was humiliating to be thrown off a rail car when loud and inebriated white passengers were allowed to stay. The wine train issued an apology after the women were ejected, promising additional training for employees on cultural diversity and sensitivity and free passes for a future trip. Katherine Neal, 85, the oldest woman in the group, said she was reminded of when she was about 12 and a store clerk asked her to eat her ice cream outside while white families ate inside.
