From Infogalactic: the planetary knowledge core
As a publicity stunt, the express train called the Transcontinental Express arrived in San Francisco, California, via the First Transcontinental Railroad on 4 June 1876, only 83 hours and 39 minutes after having left New York City. The feat was reported widely in US newspapers.
