Phases

  • Phase I – no phase changes were made. Production lasted just 13 months and only 35 units were built for two customers. Nevertheless, it is easy to find convenient spotting differences between the Southern Pacific and New York Central units that have survived multiple owners over the decades. SP units had dynamic brakes, which the New York Central did not use. These are evident in the two small rectangular intake openings in the side of the hood above the prime mover. Air was exhausted on either end of the associated roof hatch. Southern Pacific units had the largest capacity fuel tanks available, which only the second New York Central order had. The end handrails on SP units have squared off braces on either side of the gangway, while the NYC units had ones mounted on 45 degree angles. The SP units used a standard Alco teardrop shaped buffer (coupler box), while the NYC engines had built up welded plate ones.
