There is a siding in this area between 7th street and Church street. Here is the relevant description from the San Bernardino County Transit Authority Redlands Passenger Rail Project (RPRP) Environmental Impact Statement Addendum 2 (page 5, or page 110 of the packet consisting of addendums 1, 2 and 3)
"Refinement No. 6 – Downtown Metrolink Siding: In tandem with Refinement No.
5, SBCTA is proposing to place the Metrolink siding (for train turns) in downtown
Redlands. This refinement would involve placement of a two stage, siding track in the
eastern portion of downtown Redlands. The proposed siding track would extend
approximately 600 feet and be located east of 9th Street and west of Church Street. "
