The NRHS was founded in 1935
by a group of rail historians.
It has since grown from 40 founding members
to include over 13,000 men and women
of all ages and professions
in every state and many foreign countries,
making it the nation’s largest
rail preservation and historical society.
The original society was formed
as a consolidation of two of the earliest railfan clubs in the US,
the Lancaster (PA) Railway & Locomotive Historical Society
and the Interstate Trolley Club of Trenton NJ.
The official goal of the new society:
«to preserve steam and electric railway historical material;
to encourage the building of model railways;
to secure data on the history of transportation;
and to encourage rail transportation.»
