One of the interesting features of the plant was that all apparatus, except the air drills, was electrically operated, the combined motor capacity of the crushers and air compressors being about 500 hp. Another interesting feature was the use of manganese steel for the conveyor buckets, and for the inner shelves of the screens. This type of reinforcement has proved very effective in reducing the frequency and total cost of renewals.[1]
The cost of delivering crushed stone from the Fairview quarry alongside of any job within a radius of 20 miles averaged 47 cents per cubic yard, but was lowered to 38 cents per cubic yard by changing to rail-car haulage. Both figures include labour, power, maintenance of line and track equipment and general expenses.
The economy was effected by making use of returning empty cars for the distribution of supplies from Passaic Wharf.
The operation of this quarry has proved satisfactory to the Public Service Railway of New Jersey from two important standpoints:
- It has produced a considerable saving over the cost per cubic yard, but more important still, it has eliminated all dependence upon outside quarries.
- Consequently, track work had no longer to be delayed because of the failure of contractors to make deliveries.
It was planned in autumn 1911, to operate the quarry through the winter months, so that plenty of crushed rock would be available for spring operations, and even for sale to outside parties.
The quarry was in charge of a superintendent, who reported to the superintendent of Maintenance of Way. He was assisted by a clerk, a general electrician, a machinist, a dynamo man and a boss driller. About eighty-five men are employed during the busy season.[1]
