I suggest a Southern Pacific Coast Railroad That runs from Santa Cruz to Oakland in 1939. The rail ended in 1940 due to mudslides and wash-outs. There were 8 tunnels running through the Santa Cruz moutains. One Summit tunnel at Wright Station been dynamited in 1942 due to WW2. After the war, it resumed in 1947 through 1959 where the Daylight train been running.
