MAINTAINING OLD METRO SYSTEMS

Humans have always been trying to transport faster. We have advanced from basic forms of transportation like horse riding to modern forms like metro systems. Some find metro systems the most practical transportation system for major cities. Not only does it not disturb urban activities, but it also is quick. To sum up, metro is a modern and great form of transportation that is far better than the old forms. Unfortunately, not many cities have a metro system. Furthermore, not many metro systems are well-maintained. For example, the metro system of Tehran – the capital of Iran – is too old for responding to 12 million citizens. It was built in 1999 and it hasn’t been improved at all since then. In conclusion, I believe that improving defective metro systems is more important than making another one even though a majority of cities haven’t gotten a metro system yet. Related organizations should contribute to maintaining metro systems. First, they should be careful while constructing and ensure that the materials are sustainable enough. Following that, they ought to frequently repair the system to avoid forthcoming severe problems which might cause malfunction. In summary, good material and constant repairing are a crucial part of keeping a metro system in a good condition. By maintaining old metro systems, metro disasters are less likely to happen. Also, metros will function faster which saves time. In summation, maintaining old metro systems has a number of pleasant results.
