 From there, it follows the Cinderford valley northward through Upper Soudley, Cinderford Bridge and Bilson to Churchway.In 1811-12 there was an attempt to excavate a tunnel under the River Severn, apparently as an extension to the railway.The tunnel began on the bank between Bullo Pill and Newnham, and was intended to emerge on the far side near Arlingham.
