Did you know that the train tracks in South Orange were originally at street level? In 1914, the process began to elevate the tracks.
Here is a wonderful collection of photographs of the train stations, courtesy of the Steamtown National Historic Site Archives. The collection also includes photos of other stations along the train line.
There are also archives available at the New Jersey Historical Society in Newark http://www.jerseyhistory.org/, and the New Jersey State archives are located in Trenton. Contact the NJ State Historic Preservation office to find out the location of the state archives in Trenton http://www.nj.gov/dep/hpo/. The State Historic Preservation office publishes a booklet with further information which pertains to researching the history of your property. In addition, the South Orange Historical & Preservation Society, a village-wide preservation group, also publishes a similar pamphlet.
