Abstract
The researchers of leading shipbuilding research institute study possibilities to minimize the risks of hull damage for large-capacity arctic vessels in areas of ice pressure. The authors propose calculations of variants of freight vessels’ steering by two icebreakers taking into consideration ships’ characteristics and navigation conditions for icing seas. They argue optimization of engineering of transport vehicles for ice navigation.

Abstract
The author studies the equivalent circuit of traction network of autotransformer system of electric power supply with the voltage in the line between the feeding cable and the rails that differs from the voltage in the line between aerial contact wire and the rails. The article describes circuits for the system 2 x 25kW as a subcase where the number of closed circuits is halved. See the unilateral feeding of feeder zone, the considered variant shows distribution of load by the elements of traction network and allows to manually calculate the sought values for a train in the feeder zone or for a short circuit situation.

Abstract
The article describes innovative methods of mathematical simulation of interaction of the wheels and the rails of the railways. They can be employed for engineering of new traction rolling stock, and researchers can use them to define trajectories of moving conventional points on the railway wheel profile.

Abstract
The authors argue that the quality of aluminothermic welding of the rails depends on weather conditions as well as on the strict observance of process-dependent parameters. Rainy weather causes cavitation, negative temperature favors quenching defects, cracks followed by disintegration of a rail. The authors use experimental and design data to demonstrate and substantiate possibilities to enhance the technique of aluminothermic welding of a track way under rainy and winter conditions.

Abstract
The mounting of tunnel rings in an underground excavation poses some problems in engineering of possible models. Particularly, a specific software package is required in order to optimize the rotation angles between the rings, and to engineer the lining of the tunnel for its real axle should coincide as much as possible with the initially designed one.

Abstract
Permanently increasing speed of the railway traffic reduces efficiency of automatic locomotive signaling. The causes of code pattern corruption may differ but the emergence there-of represents the reason for a study and engineering of relevant technical decisions. The authors of the article propose their own variant to increase reliability of the signaling system, using the testing results of decoders of two different types.

Abstract
The authors study scheduled interval algorithm of centralized automatic control of metro train traffic, which takes into account dependencies between adjusting restrictions and system conditions. They use adaptive model of train stop time, which allows for the history of departures of the schedule of leading trains, previously departed from the same line’s stations. The algorithm is engineered for Mexico City metro and takes into account its features.
