The success of the M1 Mountain-type locomotives prompted the Pennsylvania Railroad to order 100 more locomotives of the 4-8-2 wheel arrangement in 1930, though several upgrades were incorporated in the new machines. The new locomotives became the M1a class and had a longer wheelbase than the M1’s due to the addition of the Worthington feedwater heater.  They also received the new larger class 210F75 tenders, which became known as the coast-to-coast tenders.  The first 50 M1a locomotives (#6700 – 6749) were built by Baldwin; Juniata Shops (later known as Altoona Works) built the next 25 M1a’s (#6750-6774), and the remaining 25 were built by Lima and numbered 6775-6799.

Starting in 1946, 41 of the M1a’s received further improvements by increasing the boiler pressure and the addition of circulators to the firebox.  The improved M1a’s became the M1b class.  The best way to tell them apart is to look for the circulators on the firebox, above the running boards – those round objects in a diagonal line that look like wash-out plugs.

The PRR 4-8-2’s were considered to be the finest of the Pennsy’s steam locomotives. They were designed as dual service locomotives and were put to the test hauling passenger trains, general freight, and in the end even the heavy ore trains, which there were never intended to pull.  They did it all in style!
