The railways ministry has reconstituted a committee investigating a South Korean company for violating some clauses of the contract under which 10 locomotives have been supplied to the Bangladesh Railway. The changes in the probe committee came more than three months after Railways Minister Nurul Islam Sujan ordered the formation of the committee, which was supposed to complete the work within 15 working days. In the meantime, the locomotives have been lying idle at a railways workshop in Chattogram's Pahartoli for around five months, at a time when the BR is struggling to run its operation with a big number of outdated engines.
