Platforms and tracks Future expansion Link Union Station With the number of trains using Union Station expanding, the stub-end layout of trackage is limiting the station's capacity. Trains can only enter or exit from the north side of the station. The configuration forces trains without cab-cars to slowly reverse in or out of the station and trains heading to or from the south to make a near-180 degree turn. Compounding the problem, is that while the station has 14 boarding tracks, multiple trains must squeeze onto just 5 tracks. Originally, there were more tracks at "the throat", but Metrolink had some removed to allow for faster speeds along the curves in and out of the station to improve efficiency as they enter or exit the station. This choke-point can delay arriving trains as they are forced to wait outside of the station to allow a departing train to exit the station. Departures are usually given priority, to free up platforms and to keep them from experiencing delays along their route. Therefore, Metro has proposed the Link Union Station (Link US, formerly named Southern California Regional Interconnector) Project, which would extend tracks 3–10 as run-through tracks, which will exit Union Station and cross over the El Monte Busway and US Route 101/Santa Ana Fwy on a long, elevated "S-curve" that will tie into the existing tracks along the Los Angeles River. The plan also includes tracks along the river
