It was on this date 150 years ago that the golden spike was driven at Promontory Summit UT thus completing the first transcontinental railroad. It's amazing to think about how far transportation has come in those 150 years. Of course I'm a train nut, so I love reading and hearing about how trains have changed our history. We don't even think about going between New York and LA, but imagine if you had to sail around the tip of South America to do it. Perhaps you could trek across the isthmus of Panama to cut out some time, but you had to hope you didn't get malaria or yellow fever in the process. Maybe one day we'll have Supertrain that can get us from New York to LA in only 36 hours!
