Russian freight trains

[Combine]

All the types you spoke are used in Russia. But there are two main difrrerences:
1) Freight trains in Russia are often mixed with different kinds of traincars.
2) Our freight trains are significally longer and have much weight, consists varies from 40 to 100+ wagons and weight varies from 2000t to 6000t (or to 8000t in some regions). Also sometimes "doubled" trains are formed, which consists of two normal freight trains with their locos coupled together. They can reach 12000t weight.

I also want to know which locomotives are used for freight trains.

Main freight loco series are (from the first models from 1920s): Ss, VL19, VL22, VL8, VL23, VL10, VL11, OR(N60), VL60, VL80*, VL85, VL65, TE1, TE2, TE3, 2TE10*, 2TE116. The modern freight locos are: 2ES4K, 2(3)ES5K, ES6K, 2TE70, 2TE25K, GT1.
