The Altoona Association of Model Railroaders was founded in 1949 coinciding with the City of Altoona’s Centennial Celebration. We have grown to house a very large collection of PRR builder’s plates and number boards from steam and first generation diesel from all over the country. Our layout is approx. 20'x50' combining O-scale two rail and HO. We also maintain a library dating to mid 1850's. There is something to please every modeler, railfan, and “tag along.”
