The powerhouse is fantastic!  Rose Brick has done a great job in re-using an old structure.  Mr. Oliver would be proud.

There are also some Oliver buildings left south of Sample Street on South Walnut Street.  If you leave Rose Brick, go south on Chapin to Sample.  Merge right onto Sample and at the next stoplight is Walnut Street.  Turn left (south) and before you get to the railroad tracks on the west side of Walnut is a large building that is now called the Icebox (its an indoor ice skating rink), that was part of the Oliver's #2 factory (along with the large building just north of the Icebox).  

If I am not mistaken, and some of the guys here can chime in if I am wrong, is where they manufactured transmissions for some models of Oliver tractors and built the Oliver 44(?)(Super?) and Oliver 99 (Super?) and manufactured tillage equipment at these buildings.

So, South Bend had two Oliver factories, the original Oliver Chilled Plow Company (plant #1) and the plant on South Walnut (plant #2).

If anybody can correct my information, please feel free to do so.

Hope this helps.  Glad you're visiting South Bend...Welcome!
