In 1978, the MTDB successfully negotiated with SP to purchase the SD&AE for $18.1 million, including the $1.3 million required to restore the hurricane-damaged freight line. This was a dual-intent decision, to preserve both rail freight services to the Imperial Valley, and to preserve available right-of-way for future transit use. In light of cheaper light-rail options identified in the MTDB and San Diego County studies, more expensive options such as a proposed $325 million rail-rapid transit line on a new right-of-way to the border seemed less competitive. There was agreement that using the SD&AE right-of-way and light rail technology was more economical and practical than a new rail-rapid transit line.
