Baldwin's builder's photo shows a small transitional freight Ten-wheeler design that cost the railroad $7,300. It featured a coned boiler with the large steam dome on the thicker rear course and just ahead of the firebox, which sat down between the frames. A smaller sand dome occupied the space between the leading coupled axle and the bogie truck. An extended smoke box served as base for a tall, thin capped stack and a large headlight. Guaranteed performance included the ability to haul 205-210 tons of trailing load up a 1 1/2% grade and around curves with a minimum 300 ft radius. The railroad ran from Perth Amboy along 12.5 miles to New Brunswick, NJ on 60-b (30 kg) rail. After a relatively short career, the 4 came under the scrapper's torch in 1914-1915 (sources differ).
