The advertisement was to announces inauguration of luxury tourist train 'Maharaja's Express' by railway minister Mamata Banerjee from Kolkata.

A small box inside the advertisement panel showed the train route from Kolkata to Delhi via Gaya, Varanasi, Bandhabgarh, Khajuraho, Agra and Gwalior.

As the faint background of the outline of a small map of India showed Kolkata in the Bay of Bengal and Delhi in Pakistan, ER Chief Public Relations Officer Samir Goswami said, "It is a great mistake. We apologise for this. The advertising agency has been suspended."

When contacted, owner of the advertising agency said the route alignment had been given for the benefit of passengers. "The map and the alignment are an artist's impression and not to scale. It is never our intention to create a controversy," he said.
