All of that means railways can be milked by power companies for money, which they do as the government doesn't have the guts to raise power tarrif for normal consumers because vote bank politics

But for our short sighted leaders who are only concerned with coming to power rather than running the country efficiently, bleeding railways dry is an easier way than asking power companies to charge fair tarrif, or investing in super critical technology and upgrading transmission lines to make overall cost lower.
