In May of 1951, John Prophet took his wire recorder to Interlocking Tower XC in Erie, PA. XC sat at the junction of the New York Central's 6-track east/west main line, and the north/south P&E Branch of the PRR. This was perhaps the busiest location John ever recorded from as ore and freight trains on the Pennsy ran on a continuous basis as they made their way from two nearby freight yards to the very busy "Anchor Line Docks" that sat right on the shores of Lake Erie. Iron ore and coal were the two primary commodities being moved. In addition to regular trains, John also caught dozens of steam engines running "light" between the yards and the docks; all passing his vantage point at Tower XC... all taking shipments to the steel producing cities of Pittsburgh and elsewhere. These are some of the most spectacular recordings John made.
