Twenty-two locomotives were built at the PRR's Altoona Works (now owned by Norfolk Southern); six in 1893 with {{convert|78|in|mm|0|adj=on}} driving wheels, and sixteen in 1894 with {{convert|80|in|mm|0|adj=on}} drivers, classified D14a.[3] Later, all sixteen class D14a were rebuilt to class D14b with {{convert|68|in|mm|0|adj=on}} drivers for secondary service after they were replaced in top-flight express service, while three of the six class D14 were similarly rebuilt to class D14c.[3] References1. ^1 2 3 4 {{cite web |url = http://prr.railfan.net/diagrams/PRRdiagrams.html?diag=d14_oldp.gif&sel=ste&sz=sm&fr= |title = PRR D14 Diagram |work = PRR.Railfan.net |author = Pennsylvania Railroad |accessdate = 2007-12-31}} {{Commons category|Pennsylvania Railroad D14}}{{PRR locomotives}}2. ^{{cite book |title = Pennsy Power: Steam and Electric Locomotives of the Pennsylvania Railroad, 1900–1957 |author1=Staufer, Alvin F. |author2=Pennypacker, Bert |lastauthoramp=yes |publisher = Staufer |year = 1962 |lccn = 62020878}} 3. ^1 2 3 4 5 {{cite web |title = PRR Steam Roster |url = http://www.northeast.railfan.net/prr_steam2.html |author = Chamberlin, Clint |work = Northeast Rails |accessdate = 2007-12-30}} 5 : 4-4-0 locomotives|Pennsylvania Railroad locomotives|Railway locomotives introduced in 1893|Scrapped locomotives|Standard gauge locomotives of the United States |
