The Western Railroad Museum runs their annual Scenic Express even April.  Their historic Sacramento Northern interurbans  make frequent runs though the lush springtime green hills of the Delta. The two former SN cars were supplemented by a former Salt Lake and Utah observation lounge. The museum has about five miles of former SN mainline that has been re-electrified and upgraded, and looks (to me at least) about what a well maintained interurban line probably looked like during prosperous times. The museum is about an hours drive from my house and I make the trek on two successive Saturdays.
