Prior to the Northridge earthquake in 1994 the Metrolink line terminated at the Santa Clarita station. Future plans to eventually extend the line north to the Antelope Valley were immediately expedited following the earthquake by the Southern California Regional Rail Authority in order to help relieve the traffic bottleneck caused by the collapse of the south-bound connector of State Route 14 to the south-bound interstate 5 in the Newhall Pass. The passenger platform and automobile parking lot for the Via Princessa station were constructed by the United States Army Corps of Engineers in a matter of days following the earthquake. In October 2008 a permanent building containing public restrooms and an office for station security officers was constructed. This building replaced temporary facilities that had served the station since it was first established.
22 Metrolink trains now serve the station on weekday along with 12 more on Saturday and Sunday. Sunday service began in September 2007. Weekday Metrolink service runs primarily at peak hours in the peak direction of travel while weekend departures and arrivals are fairly evenly spaced throughout the day.
City of Santa Clarita Transit provides very limited direct local bus service to the station. The trips are timed to meet the trains, in the morning hours 5 trips from Canyon Country drop off passengers at the station and in the afternoon 4 trips to Canyon Country pick up passengers at the station. All passengers on the midday trains or going to the communities of Newhall and Friendly Valley must use the bus stops on Sierra Highway at Via Princessa, approximately 0.3 miles away.
