Previous rail service in Redlands included the Pacific Electric "Red Car" trolley system and the Atchison, Topeka and Santa Fe Railway.
The PE's San Bernardino line served Redlands from Los Angeles by way of its Eastern District, which opened in 1905 and was abandoned in 1937.
Extant infrastructure includes the PE right of way, the ATSF's Redlands depot and the Redlands Trolley Barn.

Proposals for a restored passenger rail connection between San Bernardino and Redlands were made as early as the 1990s, with the service originally projected to start in 1995.
This date has progressively been delayed to 2013, 2015, and 2018.

By 2011, the estimated cost of construction had dropped to an estimate of between $130 million and $150 million.
The first contract for the project was awarded on November 2, 2011, by SANBAG to HDR, Inc. for engineering and environmental services.
The contract was an amendment to an existing contract for HDR to work on a separate project in the region, the extension of the San Bernardino Line to a new terminus at the San Bernardino Transit Center.
 Work was initially expected to begin in late 2012 or 2013, with the estimated start of service ranging from 2015 to as late as 2018.

The project encountered further delays, including the U.S. federal government's shutdown in October 2013, after which point the construction was slated to begin in fall of 2016.
In February 2014, the project was delayed again, when a San Bernardino Associated Governments (SANBAG) document said that "construction is planned to begin in late 2015 with operation in 2018."
In 2015, SANBAG officials said the line was expected to be complete and operating in 2020.
By July 2016, construction was planned to begin in 2017 and service in 2020.
In July 2016, the project received an additional $8.6 million from the U.S. Department of Transportation in the eighth round of the TIGER grant program.

The service was officially dubbed Arrow in November 2016.
The San Bernardino Association of Governments is expected to seek bids for mainline track rehabilitation valued at $132.3 million in January 2019.
