TELECOMMUNICATIONS RESEARCH IN THE UNITED STATES AND SELECTED FOREIGN COUNTRIES: A PRELIMINARY SURVEY

A preliminary investigation has been carried out on the command and control of rail transportation, both in the U.S. and overseas. An overriding consideration of rail transportation is safety, both for reasons of preservation of human life and for the high cost of a failure in potential damage to property. As such, railway signaling has evolved not only in a "fail-safe" mode, but in one where innovation must pass a series of slowly ascending levels of trial before being generally accepted in the industry. The second consideration is that of low R&D funding levels. In recent years gross investment in rail transportation has been low as the high technology fields of air and space have preoccupied governments.
