Weather permitting, NESCo's CMO and Project Engineer, along with several trained volunteer members, will be gridding and ultra-sonic testing 470's firebox wrapper and boiler, all day, October 20th. Oiling, greasing, and polishing of journal bearings will continue at that time. Visitors are welcome, but may not enter the fenced area due to safety concerns. NESCo Board officials will be on hand to answer questions from the press and public. Additional volunteer workers are not required to perform work at this time.
