Data from DeGolyer, Volume 8, p 189. See also Baldwin Locomotive Works, Illustrated Catalogue of Locomotives, 2nd Edition (Philadelphia, Pa: J B Lippincott & Co, 1881), pp. 138-142. Works number was 4287 in March 1878.
Although built for the C & A and initially in that railroad's service, this locomotive had an unusual history. It shuttled back and forth over the 6 3/4 miles (10.9 km) between Camden and Haddonfield, 11 3/4 miles (18.9 km) between Camden and Lakeside, and 19 miles (30.6 km) Camden-Atco for about 20 years. Baldwin's Illustrated Catalogue included tables of repairs and running costs for the John Lucas. Superintendent F A Lister's 15 September 1880 commentary reported that the daily run mileage averaged 143 miles (230 km) or 33,261 miles (53,550 km) in 1878 and 34,907 miles (56,200 km) in 1879. Average speed was 20 mph (32 kph). Coal consumption averaged 3,984 lb (1,807 kg) per day and a tank load of water sufficed for pulling two cars over 20 miles. According to [
