Location: Alex Brown & Sons Foundation Gallery 

The railroads were an important influence on the standardization and development of time zones across the nation because precision timekeeping was essential in maintaining the safety of the railways. Learn how Webb C. Ball developed precision timekeeping by exploring the collection of 21 clocks and 12 pocket watches that were used by conductors and engineers on the B&O Railroad lines. The exhibition provides deeper knowledge of the B&O Time Service Department, which handled the repairs and adjustments for the railway clocks, and gives guests a chance to test their knowledge of the U.S. time zones by adjusting manual clocks to match the regional time zones.
