Take a walk on the Key System's C Line this Saturday, with a train aficionado named Daniel Levy. The tour sounds like a great opportunity for anyone who wants to trace the C Line and loves train lore.

This Oakland Heritage Association tour will follow early-day Key System commuters on their way to the Key ferries.

Walk past the train yard, through the Key System 40th Street Cut, and over to the old Key System station and mural at Piedmont Avenue. Then learn about the Key System’s plan to build a line though Piedmont and Oakland to San Jose, while you walk the full line. And then finish this flat walking tour on Piedmont Avenue.

Also join everyone for an optional lunch afterwards, to cap things off. This Key Line stopped operating back in 1958, when cars took over...too bad we didn't keep this mass transit in place!

When: The tour will start at 10am and end at 12:00pm, at least the part that involves walking up the Key Line. There's an optional group lunch which will likely take another hour.

Where: The tour will meet at MacArthur BART Station underpass on 40th Street. At the end of the tour, you can walk or take a bus back to that BART station.

How much: As part of the Oakland Heritage Alliance's seasonal tour, they request donations of $15/head ($10/head for members) to benefit the Alliance. Lunch is extra.

I cannot remember a time when I did not love trains. In my Trestle Glen home, I used to go exploring in my backyard, fantasizing that I would find some old Key System track. When I got older, I explored old streetcar right of ways with my dad and created a website with the photos I took (www.oberail.org).

For my Eagle Scout project, I wanted to share my love and knowledge of the Sacramento Northern Railway, so I researched, designed and installed informational signs on the Temescal and Montclair bike paths, where the trains ran.

My love of transportation turned to love of cities as I continued to explore and as I worked at AC Transit last summer. I am interested in bringing Oakland to its full potential and making public transportation an attractive alternative to the automobile.
