MacArthur station was built with cross-platform interchanges in mind.
There are two island platforms and four tracks.
Platforms 1 and 2 serve the Richmond-Fremont line and the Richmond-Daly City/Millbrae line; Platform 1 goes Northbound towards Richmond, and Platform 2 goes Southbound towards  Berryessa/North San José and Daly City/Millbrae.
Platforms 3 and 4 serve the Antioch–SFO/Millbrae line; Platform 3 goes Northbound toward Pittsburg/Bay Point, and Platform 4 goes Southbound toward SFO/Millbrae.
Connections between the lines are timed for Southbound passengers between Platforms 2 and 4.
This is not the case for Northbound passengers, as a timed transfer point already exists further south at 19th Street Station.
MacArthur tends to be crowded in the morning due to high transfer volume between two lines where only a few people get off while many are trying to board.
Southbound trains converge to single track towards downtown Oakland, and San Francisco bound trains are given priority when departing in that direction.
