Train services were on Friday affected in Kharagpur and Adra division of south eastern railway due to 'rail roko' call given by Bharat Jakat Majhi Pargana Mahal (BJMPM), the largest outfit of tribals in west Midnapore, SER sources said.

The outfit has called the 'rail roko' to protest the 'Hool Divas' not being properly celebrated in the state. They also demanded that importance should be given to their Alchiki language.

30 June is commemorated as Hool Divas by tribals in memory of their 30,000 ancestors who were martyred during the Santhal Rebellion of 1855-56.

The services have been affected since 6.30 am on Friday. Agitations have been organised at Nekurseni and Khemasuli stations of Kharagpur division, and Chhatna, Madhukunda, Garhdhrubeswar and Salboni stations of Adra division, the sources said.

Three trains, Khargpur-Hatia passenger, Kharagpur-Tatanagar passenger and Adra-Mednapur passenger, have been cancelled. Several other trains, including Howrah-Mumbai Duronto, have either been terminated, controlled or detained, they added.
