Cement production in Eastern India has been severely hit due to an acute shortages of railway trucks required to transport clinker. Production was hit the hardest in the past two months. Cement units of Gujarat Ambuja Eastern, Lafarge India, Larsen & Toubro (L&T), ACC and Birla Corporation are operating at about 50 per cent of their capacity, with no trucks available to move required clinker from Madhya Pradesh and Chattisgarh. Spokesmen say it is not commercially viable to transport clinker via roads with transportation via railway costing about Rs 600 per tonne, by road the costs would be about Rs 1200 per tonne or more.
