I know its sad to know that some stations are not developed, but let me tell you that there is no use of the MP raising the issue or whatever in the Parliament. It is left to the RM to decide whether the work(major work) will start or not. For example MP from Mangalore, Nalin Kumar Katil, had requested many things with the RM, but none of it has materialized.
IMHO, IR is ignoring Southern India. Most of North India is electrified even though some lines in south India were laid almost 100 years back !
