Shaheed bhai..lalu is one of the most shrewd politicians in the entire country. He knows what he is doing. He played with Bihar because he did not care less. For the Railways, he is just reaping the benefits from the seens sown by Nitish Kumar (Rly minister before him). Plus he wants to be PM in the future. So these are all his gimmicks. Railways might be in profits because lalu wants it to so that he can get more vote banks. In Bihar, he did not need to prove anything to win votes for a long time until people finally realized and kicked him out.
