The Old Spaghetti Factory in Sacramento. Not only does it look out over the ex-WP line, but it is in a former WP Depot. Same situation for Feather River Brewing in Oroville.

Paradiso's Deli, which I think recently closed, is / was spitting distance from the Coast Line just south of the San Jose depot. Sit in the front patio and you could hear the CalTrain parade. Had to stand to see, but you were usually too focused on your meatball sub. Used to know the owner. Awesome little deli / sandwich place.

There used to be an A&W on Alameda and Stockton in San Jose, later and for far too short a time, it became Q and Brew, a great BBQ place. Used to eat there sometimes as it looked over the north end of the San Jose depot yard. Now it is an empty lot waiting for a Whole Paycheck to be built.
