Who is asking the poor to travel by train only. Let them take BMTC. Right from morning 4 am I see 222A and many other buses to Kengeri. Let them take Bus Pass which works out well. Or daily Pass for 24 Hrs. Most of the articles and arguments are presented in a manner which assumes that if there are no trains there is nothing beyond.
Why does everyone keep forgetting that Bus is there - most widely used means of transport in this country (various state govt undertakings - city, village, intra-state, inter-state and also numerous private buses). In this case - World's largest Govt. City Bus fleet is there.
