Answer» Explanation: The report has declared the cost of railway department expensive because of the use of iron. Iron is USED everywhere in railway department from construction of trains to the track. Iron is used in every single step. At some PLACES Iron is used as it is and also used as an alloy e.g. STEEL to avoid rusting. The FACT that due to iron use cost has increased is that most of the time iron can not be used alone rather it is used in an alloy form to withstand the load of heavy trains. Thus, alloys are relatively expensive. |
