PREORDER NOW – EXPECTED DELIVERY OCTOBER 2017
In 1930, the celebrated success of the M1 Mountain-type locomotives prompted the Pennsylvania Railroad to order 100 more locomotives of the 4-8-2 wheel arrangement. 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 new larger tenders, class 210F75, which became known as the coast-to-coast tenders.
