SERVANT OR MASTER?
Railroads are again at the forefront of applications of new electronic data processing technology. While minicomputer and microprocessor applications are growing at a faster rate than very large mainframe computer installations, a survey by AAR Data Systems Division shows that the number of midsize mainframes is actually declining. This indicates that railroads are turning from slower medium size computers to either large units with high capacity or to minis which can perform specialized tasks at slower speed and involving only limited capacity. Minis are applied in centralized traffic control, signaling and engineering design; microprocessors may be teamed with minicomputers in applications such as CTC. While the problem of rapid obsolescence of semiconductor devices is one which the industry is struggling with, the labor-saving potential promises continued growth in use of such devices.
