Believe it or not, the "Dan Patch Electric Line" was originally it's own line (the Minneapolis, St. Paul, Rochester & Dubuque Electric Traction Co.), which was powered by gas electrics. It was built in 1908 by Col. Marion Savage, who was the owner of the famous race horse, and ran from his farm (in what is now Savage, MN) to Minneapolis (Bloomington, MN... where the Mall of America is). The line was bought by the Minneapolis, Northfiled & Southern which operated the line until it was bought by the Soo Line in the early 80s. From what I can tell, the line went into receivership and the owner of the Central Warehouse Co. and the Minneapolis, Anoka and Cayuna Range bought some of the equipment from the Dan Patch Electric lines, but there doesn't seem to be any evidence that the line was ever electrified from what I can tell.
Here's a couple of blurbs on the original Dan Patch line...

The Minnesota Transit Museum has Dan Patch #100 the second gas-electric locomotive built in the US...
Locomotive #100 is interesting as it was a gas electric when it ran on the Dan Patch line, was converted to straight electric (using streetcar technology, including poles!) when it was sold to the Central Warehouse Co., continued to do so when it also worked for the Minneapolis, Anoka, & Cayuna Range. The MA&CR was aquired in 1943 by the Northern Pump Co.'s spin-off, the Northern Ordinance Co. to transport workers to and from a new plant it constructed. In 1946 the MA&CR was de-electrified, the streetcars that ran on it's system scrapped and #100 re-engined with a Waukesha diesel engine and generator. In 1964, FMC bought Northern Ordinance, including the MA&CR and two years later it was purchased from FMC by the Northern Pacific and loco #100 donated to the Minnesota Transit Museum.
So, while the Dan Patch Electric Lines may never have been electrified, engine #100 was... and then converted to diesel. And the Minneapolis, Anoka & Cyuna Range adds to the list of electric to diesel lines on our list (although it shouldn't be confused with the Dan Patch line).
Interestingly enough, the Twin Cities has been doing feasibilty studies for building commuter rail lines in the Minneapolis/St. Paul metropolitan area. One of the corridors they want to build in is the old Dan Patch Line, and the corridor will also bear the Dan Patch name.

Although, given the negative views of the line by the NIMBYs, the project may not go through. (Maybe if the line was electrified, they wouldn't complain about noise that much?) We'll have to see.
Also, Canadian Pacific has spun off the former Minneapolis, Northfield & Southern to Progressive Rail, part of which, was the original Dan Patch trackage.

So, in one sense or another, the Dan Patch Line is still in use.
Edit - did a little more surfing and found this bit about the MA&CR. I didn't think it warrented its own posting, so I added it here...
