Conclusion
Summing up all, the ventilation rate was calculated taking into consideration the given exchange volume of air, temperature of air and excess heat in the premise [36].
In this case of ventilation the best option can be an air conditioning i.e. automatically maintain its status in environment and in accordance with certain requirements for example, set temperature, humidity, air mobility and regardless of changes in state and outside air conditions. As we know the temperature difference in the vertical and horizontal spaces should not exceed 2 degrees Celsius and relative humidity should be 40-60%, air velocity about 0.1 m / s and temperature of 21-24C.

So it can be clearly seen that the working place meet all the necessary requirements according to the created conditions. That can lead to a working productivity and development of new technologies.
CONCLUSION
This diploma project is dedicated to the development of secure freight train routing system. The priority of development is to provide accurate calculations and security.
Considering the results of diploma project the secure freight train routing system was researched. The task of defining secure freight train routing system has been widely discussed and studied. The necessity of secure system usage in train routing and the need to use computer technology were identified and justified in this diploma project.
During the development process, the secure freight train routing system has been designed and implemented which involve website with algorithm description.
The role of transport system in Kazakhstan was analyzed as well as in the world. Secure freight train routing system was selected. The necessary steps for the creation of the given system were identified. All disadvantages were collected from the previous systems and eliminated in our system. During the implementation, the main features of the developed system were clearly described as well as its functionality and mechanisms. Also, the usage of other appropriate technologies was found to widen the purposes of the diploma project.
The software implementation part of the diploma project shows that it fully meets the task. The phase of testing did not reveal any significant errors. All comments and suggestions made by the testers will be taken into account in the future. In addition, it has great functionality and user-friendly interface. Also the software application that shows how the algorithm works has a simple interface with clear mechanism.
Next step was an assessment of economic efficiency. It concluded that the
project has a positive economic efficiency.
During the implementation of this diploma project goals and objectives that were set at the beginning were accomplished.
