Authorities say the Atlanta Streetcar has been involved in two crashes with vehicles while being tested before next month's expected launch. Streetcar spokeswoman Sharon Gain tells FOX 5 News that a car and the streetcar collided Sunday near Centennial Olympic Park. She said the driver tried to pass the streetcar while it was turning during a test run. Last week, a driver was accused of hitting the streetcar on Ellis Street. No series injuries were reported in either crash.
