Years back, when state bond money was used to purchase the right-of-way (ROW), a letter roughly described the width of the ROW. Keep in mind that 52 feet is all that is needed for three tracks, and 68 feet is all that is needed for FOUR tracks.

"This letter agreement sets forth the terms and conditions pursuant to which the Peninsula Corridor Study Joint Powers Board ("JPB") and Southern Pacific Transportation Company ("SP" or "SPT") will purchase certain SP properties in San Francisco, San Mateo, Alameda and Santa Clara Counties for passenger commute operations."
