Three L's.
A New Lots Ave-bound 3 train (Kawasaki R62, 1983-1985) is seen flying over Livonia Ave station, where three L trains can be seen below - two R143s (Kawasaki, 2001-2003) and one R160A (Alstom, 2005-2010). The close headways of the L trains are due to the Communications-Based Train Control (CBTC) and Automatic Train Operation (ATO) systems installed on the line.
