As I saw the water scarcity issues around the country, I felt that our vast railway lines can also double as a water pipeline across the country. This can help move water from anywhere to anywhere in our country. Most of it could be based on gravity flow and some places may need a force to flow water to higher planes. Motors along the lines either powered by solar or by energy used by moving trains can be used for these purposes. This can lead to reduced costs of lines as they become multi purpose and will also create a sharing network across our. country. The lines can be embedded with hollow water pipes during manufacturing and the last mile to villages can be through transportation from its nearest railway station.
