The first locomotives of the MacArthur design that Baldwin Locomotive Works built were USA 190–200 for the WP&YR, which makes them unique. This initial 1942 sales order to Baldwin for 60 MacArthur gauge locomotives was for India's extensive meter-gauge railway system. The first eleven were diverted to the WP&YR as gauge, the next 15 went to India as meter gauge, another 20 went to Queensland Rail as gauge, and the remaining 14 were meter gauge for India where the order was destined before the Alaskan and Australian diversions.
