75 years ago LA was simply bursting with trains, so much so that it was decided the region needed a Union station to consolidate tracks under one roof. This Saturday Union Station celebrates its 75th anniversary with a big public party. And an exhibit opens at Los Angeles Central Library together with a book Los Angeles: Union Station. Marlyn Musicant curated the exhibit and edited the book. It turns out the process of getting the now beloved station built was fraught with hostilities, delays and downright racism.
