What factors determine the price of mining electric locomotives?

What factors determine the price of mining electric locomotives? We believe this is the question of many customers. 

The composition of the price of mining electric locomotives is similar to the composition of automobile prices. They are composed of two parts, the basic price and the customized price.

The former refers to the basic production cost of each electric locomotive. Such as the materials used, processes and testing methods, etc. The latter refers to the cost of individual configuration according to customer needs. For example, if there is gas in the working environment, it is necessary to choose a special explosion-proof mining electric locomotive, and it is also necessary to be equipped with a gas power-off device. In addition, there are temperature, humidity, working intensity, etc., which will have different requirements on the parameters of mining  locomotives. Different parameters affect the final quotation of mining  locomotives.
