TL;DR: In this article, the effect of the noise interference with the speech transmission is reduced by eliminating the high peaks of noise of very short duration and depending upon the persistence of sensation of speech in the ear to bridge the gaps.
Abstract: IN TRANSMITTING speech over radiotelephone circuits there are a number of conventional methods of increasing the signal with respect to the noise. Examples of such methods are the use of higher power, directive antennas, diversity reception, and filters to narrow the received frequency band. In addition, there are other methods of a special character which reduce the effect of the noise interference with the speech transmission. One example of such a device limits the noise interference by eliminating the high peaks of noise of very short duration and depending upon the persistence of sensation of speech in the ear to bridge the gaps. Another method diminishes the noise in intervals of no speech. This is the method which will be discussed here.

TL;DR: In this article, a typical train installation operating through a highway channel is described, where a coin box is used on the train for radio-telephone service, and the arrangements for this purpose are also described.
Abstract: Experimental public radio-telephone service for train passengers was inaugurated by the Bell Telephone System several years ago. Initial installations operated in conjunction with a series of urban mobile base stations. More recently, highway mobile systems have been used for this service, and this paper describes a typical train installation operating through a highway channel. All of these early systems utilized an attendant on the train. The cost of providing an attendant has, in some cases, been found excessive. Consequently, experiments have been initiated in which a coin box is used on the train. The arrangements for this purpose are also described.

TL;DR: The connection of ordinary telephone systems by means of long radiotelephone links presents some unique and interesting technical problems that require voice-operated switching devices to suppress echoes and singing.
Abstract: The vodas is used in radiotelephony to switch the voice paths rapidly to and fro, and thus prevent echoes and singing that would otherwise occur at unpredictable times. It is also used to save privacy apparatus by permitting the use of the same apparatus for both directions of transmission. The performance characteristics of the electromagnetic relays used in the vodas are very suitable in that they have small operating and constant releasing times. Improved performance of the voice-operated relays in the presence of line noise can be secured by the use of a syllabic type of vodas which discriminates between the characteristic voltage-time envelopes of the noise and speech waves. Laboratory and field tests indicate that this device even without delay circuits, gives slightly better performance on most conditions than the original vodas with delay. When provided with a transmitting delay circuit, the syllabic device is decidedly better than the older vodas.

TL;DR: In this paper, the authors describe component parts of the train telephone system, results of radio coverage tests on the routes involved, and devices employed to control two-way transmission, and some results of the experimental operation are pointed out.
Abstract: Telephone service was made available experimentally in 1947 to passengers aboard certain railroad trains operating between New York, N.Y., and Washington, D.C. Communication between these trains and the telephone network is effected through radio stations of the urban mobile telephone services of the Bell System. This paper describes component parts of the train telephone system, results of radio coverage tests on the routes involved, and devices employed to control two-way transmission. Special features of the installations which differ from previous mobile installations and some results of the experimental operation are pointed out.
