Just to digress a bit, for those who may have been lucky to visit Ethiopia, the Inter-City highways are fenced and it is a bliss to drive on them, with designated passes for the population. The minute you have a railway line where children play cha mama cha baba, wazee are on Ajua and mamas regularly do kamweretho besides the rail track, it will be disastrous.
