The trolleys are based on a type of cargo carriages used to carry bulk loads. The difference between these tugs with a tall trolley is that the bulkheads have drainage valves on the lower or the sides.
The above-mentioned wagons are of two types:
۴-۱٫ The ball is open on the open
۴ .۲- The ball is over
Outdoor carriages for carrying minerals are also used, which are shipped by long-distance carriages. Top-fit wagons are worn over to carry powdered cargo. These wagons shift loads of less than the ridge height, so they are more voluminous.
At present, the Sepahan Company (special joint stock company), which owns 80 cars, is on a lease line.
