“…The steam locomotive is one of the unique artificial pieces of engineering and the role of the steam locomotive in history can hardly need to be stressed [5][6][7][8]. Thanks to this, rail transport emerged, and it was steam locomotives that carried out the bulk of transport in the 19th and first half of the 20th century [9][10][11] and played an important role in boosting the economies of many countries.…”

This article’s main subjects are the theoretical underpinnings of a steam locomotive’s conceptual layout, engineering design, and calculations, which will be necessary when making a working model of the locomotive. A steam locomotive is a locomotive that uses steam as its power source and steam engines as its engine. The design of the main components of a steam locomotive, including the steam boiler, the steam engine, and the locomotive underframe, has been discussed in this article. To better understand these issues, the article also includes the design of a steam locomotive model created using the CATIA V5 program and the calculation of main components. Calculations of the main parameters of a connecting rod are performed. There are calculated forces efficiency, pressure and power. These parameters are very important for the proper design of the miniature locomotive model. Additionally, the steam boiler is analyzed by means of the finite element method. The analysis has shown that the boiler structure is able to withstand the steam pressure during the locomotive operation.

The paper proposes a new approach to solving the problem of increasing the economic efficiency of railway transportation of viscous petroleum fuels (fuel oils) at low air temperatures. The physical properties of fuel oils allow them to be obtained when poured into the tank of a tank wagon in a stratified state, when their density in the upper part of the tank is significantly less than in its lower part. This blocks the natural convection of hot fuel oil on the cold walls of the tank, and it cools only due to the molecular thermal conductivity which is very small. Upon cooling down, a relatively thin highly viscous layer forms on the inner walls of the tank of a tank wagon, which acts as a heat-insulating shell, and the bulk of it (more than 90%) retains high temperature and fluidity throughout the period of transportation. The thermal and hydrodynamic calculations were performed using modern computer technologies (the ANSYS 5.6 software package). The results obtained show that the need to heat up the fuel oil during unloading remains, but already requires significantly less time and heat energy. The proposed energy-saving technologies for the delivery of viscous petroleum products are especially relevant in Russia with its cold continental climate, long-haul transportation, and the current structure of the country’s wagon fleet. The value of the results obtained lies in the fact that the proposal can be implemented on tank wagons in circulation with minimal change to their design. The technology of operation of the drain equipment at unloading points will not change either.
