This HZ's unit no. 1061-103 is a representative of the subclass 100 (the existing subclasses are 000, 100 and 200). It can be observed that it has a slightly different side in comparison with the subclass 000 (seen behind).
Here we have three 1061 units coupled together; the 3rd (rightmost) risen pantograph belongs to the third locomotive.
