Abstract: The intersection connection of locomotive cryogenic systems includes a flexible double-wall corrugated pipeline having two corrugated pipes made of cold-resistant steel, which are arranged one inside the other and separated by elastic inserts. There are end adapter flanges fixed to the end walls of the locomotive adjacent sections, and an elastic bar connected to the flexible double-wall corrugated pipeline with suspensions. The intersection connection can be provided with an elastic bar aligned relative to the inner corrugated pipe with centering elastic inserts.

Abstract: The method effects control upon engines, in particular to regulating power of a gas-turbine-generator system used in gas-turbine locomotives, hybrid locomotives, etc. A control signal for the fuel metering unit actuator is formed by an electronic engine control system on the basis of processing of a signal from a turbine rpm sensor and a design value of the generator active electric output power. The system power can be preset. A preset power value is compared to a real power calculated value which is obtained according to measured values of current and voltage. An obtained difference is taken as the basis for forming a control signal for the fuel metering unit actuator in order to provide a certain turbine rpm and a control signal for a current regulator supplying energy to the generator excitation winding in accordance with the load curve of the gas turbine-generator system.
