Train types/compositions

[noname]

It's rather difficult to say that "Rostov-Shakhty" is the train's name. As you've mentioned, it shows only starting and ending point, but we should remember that there can be a great number of trains with the same service like Saint-Petersburg - Moscow. So every passenger train has two unique numbers. For example: №229\230 Saint-Petersburg - Anapa.
Also there are some trains which have their own names like famous "Red Streak" or "Sochi".
