This issue presents three reports. (1) "The Operational Experience of Semiconductor rectifiers on the West-Siberian railroad". There is occurring at present on the West-Siberian railroad a widespread replacement of mercury rectifiers with semiconductor rectifiers. As the year of 1972 approached over 50% of the rectifiers in operation were semiconductor rectifiers. In the article the operating reliability of semiconductor rectifiers is compared with that of mercury rectifiers. The automation system is described, including ventilation, dependent upon the valve's body temperature and protection of the transformer assembly from overloads. (2) "Adjustment of power case phases of the VIPE-I type inverted rectified converter". Shown are the methods for adjusting the type VIPE-I inverted rectifier unit as worked out on the Sverdlovskii road. Adjustment of power case phases of type VIPE-I converters is included in the verification of the correspondence of the installation to the schemata, the distribution of reverse current between the sequentially coupling thyristors, the formation of impulses by discharge cascades and the presence of these impulses on the controlling electrodes of all power case thyristors, and the distribution of current between the parallel coupling thyristors in realizing the protective adjustment against valve flashover and overload. (3) "The Condition and Perspectives for Introduction of Semiconductor Converters on Traction Substation of Electrified Railroads. This is a short exposition of reports and recommendations accepted by participants in the technical scientific conference meeting in September 1971 in the Pavilion "Transport USSR" of the All-Union Exposition of National Economy Accomplishments.
