Drawbridge tender walking to work on the Norfolk Southern (ex-Nickel Plate Road) drawbridge spanning the Cuyahoga River in Cleveland, Ohio, in March 2005. In the background are Terminal Tower, a shopping mall that was once the cityís main rail passenger terminal, and Key Tower, headquarters of Key Bank and the tallest building in Cleveland. Most drawbridges are staffed 24/7/365 in eight-hour shifts by on-site tenders who coordinate train and boat movements. Their jobs can range from hectic to mundane depending on traffic levels. The Nickel Plate Drawbridge in Cleveland is high enough that only the largest boats require a lift, only one to two in a typical day. It is quite possible that no lifts will be required during this workerís shift, while only two to four trains will likely pass. Throughout its history, railroading has required long, sometimes monotonous hours of work to ensure safe operations.
