McCowan station was the terminus station of Line 3 and lay just west of
McCowan Yard (completed in 1983), which stored and maintained Line 3's trains. Trains used a double crossover before the station entrance, but only one side of the station was used. In earlier years both platforms were used for line-end and westbound trains, but the double crossover allowed eastbound trains to cross over to the westbound platform, making for a more efficient system. The eastbound track was used when taking trains out of service. This allowed the operator to ensure that the train was empty with no one boarding before bringing the train to McCowan Yard. ==References==
