This building is now in
          commercial use and not easily recognized as a link with
          our industrial past. It was built by the Union Traction
          Company as a battery house/power plant for the trolleys
          on Germantown Avenue and is an example of an early
          technology that fell out of use by World War I. It served
          two functions: it acted similar to a surge tank on a car
          radiator when there was a line drop, and it provided
          extra power when needed. Direct current (d.c.)
          electricity necessary for the trolleys cannot travel over
          long distances, the limit being about six miles. Battery
          stations at strategic locations made up for the fact that
          portions of the line were far from the substation, in
          this case the Chelten Avenue Substation. The batteries
          were charged by the line in off-peak times when there was
          a line drop and were put on line at peak load
          times. 1
           
          
          The transit line at that date extended to Northwestern
          Avenue, and the ascent of the hill on Germantown Avenue
          in either direction made heavy demands on the electric
          power available. The cars of the Union Traction Company
          (later Philadelphia Rapid Transit Company in 1902, and
          then Philadelphia Transportation Company in 1939) made
          connections with the Lehigh Valley Transit Company,
          operating lines to Lehigh County, and the Schuylkill
          Valley System, extending through Montgomery County to
          Pottstown.  
          
           
          
          The battery station went out of use c.1919. Up until that
          time the traction company had generated its own power,
          but went out of the power business in the 1920s and
          turned over its power facilities to the Philadelphia
          Electric Company, obtaining the power for traction at a
          very low tariff, which continued following the
          electrification of the
          
           
          
          Subsequent use of the building has destroyed any trace of
          its original use. The building is a one-story, stuccoed
          brick commercial building recently altered and modernized
          with mansard roof and new openings. There were changes
          made in the building in 1919, but the change in use is
          not known.  A building permit in 1955 probably
          signifies the date when the building was occupied by a
          Volkswagen repair shop. Following this use, an antique
          car collection was stored in the building. In 1984 the
          present owner made renovations for commercial use, and
          three businesses are now in operation: Sherlocks (hair
          salon), Renaissance Real Estate (office), Little House on
          the Hill (developmental learning and child day care). The
          present owner is George Lapworth of Renaissance Real
          Estate.

Update May
          2007 (by
          Jane Mork Gibson):
          
          Currently called “Little House on the Hill," a
          daycare center occupies the entire building, with a play
          yard outside. It was established in 1983 and is operated
          by Carrie O’Donnell (“Miss Carrie"). George
          and Marie Lapworth own the property. A sign on the
          building provides the following information:
