Besides, Railways has also effected partial cancellation of three pairs of trains and diverted two pairs to avoid passenger inconvenience during the period.
The foggy conditions during the winter season pose a great challenge to the Railways, especially in the northern region of the country in terms of operations and safety, the official said.
