Thanks to the generosity of Walter Stafa who loaned me a copy of his plan book to scan, many more PRR plans are now online! Also, thanks to Pat McKinney who loaned me his plan book with about 300 plans, the earliest being from the 1890's! Also, thanks to Michael O. Brown who sent scans of some other missing plans and to Eugene Diemling who sent me a CD with many more plans that he had and Charles Crawford for filling in some holes. Lastly thanks again to Pat McKinney for loaning me even more plans to add here!
