In 1849, PRR officials developed plans to construct a repair facility at a town newly established for this purpose, Altoona.[1] In time, additional PRR repair facilities were located in Harrisburg, Pittsburgh, Renovo and Mifflin, and the Altoona Works expanded in adjacent Juniata.Inventor Alexander Graham Bell sent two assistants to the Altoona shops in 1875 to study the feasibility of installing telephone lines.During World War II, PRR facilities (including the Altoona Shops) were on target lists of German saboteurs involved in Operation Pastorius.[8] By 1945, the Altoona Works had grown to be one of the largest repair and construction facilities for locomotives and cars in the world.
