A new minicomputer at Union Pacific's Omaha headquarters produces, stores and retrieves signal department drawings within seconds of entry. At present 5 drafting stations are equipped with dual 19-in CRT screens tied in with the minicomputer. Production of the signal drafting section is expected to triple as a result of the new installation.
