The operation recorded at this borough is a mineral plant working columbium and tantalum — columbium being the older American name for niobium. Those two are the materials of superalloys, capacitors and specialist steels.
Neither is a mine. This is a processing operation, 0.66 miles from the centre of the borough, and what it works did not come out of the ground anywhere near here.
So the freight runs inbound, up the valley from a port
Neither niobium nor tantalum is produced from United States ore at commercial scale, so what arrives is concentrate or oxide that came in through a port. This borough sits 10.5 miles west of Reading, inside a day of Philadelphia and of the New York and New Jersey docks.
That is the reverse of almost every other address on these Pennsylvania pages. The stone country around here loads out; this one takes in, which changes what the trucks on the yard were bought to do.
Everything around it loads out
Those neighbours are all outbound rock. The Denver Quarry lies about 8.7 miles south with 16 people on the books, Prescott Quarry about 11.5 miles west at Avon with twelve, and the Leesport Quarry about 11.9 miles north-east with 13.
South and south-east into Lancaster the same pattern: Hinkletown Quarry about 13.3 miles south at Blue Ball with 16, and Silver Hill Quarry about 13.6 miles south-east at Bowmansville with 16.
North-east, the Mid-Atlantic Quarry about 13.2 miles at Shoemakersville runs two people.
The scale sits a little further out
Beyond those pits the bigger plants take over. The Evansville Plant at Blandon, about 15.4 miles north-east, runs 173 people on the books, and Dyer Quarry at Birdsboro about 16.1 miles east runs 28.
Closer in, the rail is the Reading yards about 11.4 miles east, and the Mount Penn Preparation Plant about 13.4 miles south-east at Flying Hills works coal with three people.
So the working day out of this borough is a short run east into Reading or south into Lancaster, rather than a long haul in any direction.
Brakes, clutch, suspension and tyres go before the engine.
