Transport infrastructure within Chad is generally poor, especially in the north and east of the country. River transport is limited to the south-west corner. As of 2011 Chad had no railways though two lines are planned - from the capital to the Sudanese and Cameroonian borders during the wet season, especially in the southern half of the country. In the north, roads are merely tracks across the desert and land mines continue to present a danger. Draft animals (horses, donkeys and camels) remain important in much of the country.
