Minister for Railways Khuwaja Saad Rafique on Thursday inaugurated a special purpose 'Xmas Peace Train' ahead of Christmas festivities in the country.

The minister, while addressing the inauguration ceremony, hailed the role of minority groups, especially Christians, in the development and prosperity of Pakistan.

"The white colour of our national flag denotes minority groups, and it is incomplete without them," he said, adding that this train would serve as a symbol of unity, tranquility and harmony wherever it would go.
