Standard Time:
Up until the National Railway Time Convention adopted a National Time Standard in 1883, each railroad company maintained its own standard time with little coordination with other companies. In the late 1870s, the Union Pacific Railway operated its trains across six different time standards.
The National Time Standard was based on a national time hour set by zones separated by the 7th, 90th, 105th and 120th meridians west of the Greenwich, England prime. This standard, still in use today, was legalized by Congress in 1918. |
