Train aficionados -- some of whom had waited hours for the opportunity -- snap photos of the Union Pacific steam engine Big Boy No. 4014 at the Kennedy Road railroad crossing in the town of Grove on Thursday afternoon. The engine, on a coast to coast tour as part of the nation's 250th anniversary this summer, passed through the northeast corner of Allegany County on the Norfolk Southern line, past Swain and Canaseraga before heading to Steuben County.
