Post WWII era. See the end of the streetcar lines, the National City Lines take-over, and the continuation of the bridge trains until 1958. We review the similar NCL takeovers of some other large and famous electric lines that all seemed to be targeted for replacement by buses at the expense of rails.
Revisit all the lines from A to F in the years remembered by most. Highlights include the former Sacramento Northern electric interurban trains that ran on the C-line until 1941 and the freight operations that continued until 1957. See the Key System's yards, work equipment and shops.
