NOT RAIN, NOT HUMAN ERROR

This is disgusting. Yesterday's train derailment in Nairobi was due not to rain, not to speed, not to human error but to "flying toilets". Where latrines are lacking in slums, inhabitants relieve themselves in plastic bags and then hurl the waste away from their dwellings, in this case onto the railway line. This caused excessive wheel slip in yesterday's accident. Two bodies have been retrieved, but they won't know how many died until the wagons are lifted and the containers are removed.
