What were the names of the two trains that met face to face for the first time at Promontory Summit Utah?
Don’t know of any names having been given to the trains, but the CPRR engine was the Jupiter and the UPRR Engine was #119. There is an eyewitness account of the CPRR train trip from Sacramento to Promontory Summit by Dr. Stillman, and David Bain’s Book Empire Express includes a description of the trip on the UPRR train. Another FAQ also relates to the first trains.
