Compiled from handwritten notes, dating from 1978-1988.

Most of this information was transcribed from handwritten notes taken while doing research in the files of UP's engineering department during 1982-1983, then compiled as a computer file in 1988, with additions through September 1994.

The notes from the early 1980s were completed prior to the closure of UP's engineering office in Salt Lake City in about 1984. All files and most personnel were moved to Omaha in 1983-1984. The office was located in the Utah Division offices in the former depot annex building, just south of Union Pacific's Salt Lake City depot. The building was demolished in 1999 to make room for The Gateway Project.
