"I am sorry to say that the Prime Minister inaugurated one rail project on Friday. If anything serious happens, we should avoid all political and even government programmes," Banerjee told mediapersons here on her return from New Delhi.
Modi flagged off the indigenously built Train 18, now christened as the Vande Bharat Express, from the New Delhi railway station on Friday.
Banerjee also attacked the Prime Minister for not declaring three-day mourning.
