WKMG, Channel 6 in Orlando, is reporting that at around 2 am Sunday morning, a monorail (reported as Pink) collided into Monorail Purple which was not moving at the time at the Ticket and Transportation Center, killing the driver on impact. No other injuries have been reported and no further details are currently available.
