I'm afraid your right. we, the group of 4, are told to give a seminar on Modulation of Indian railways. My topic being COACHES, I'm told to explain current railway coaches and their design and methods to improve the present COACHES of IR. I have tried comparing LHB coaches ,which are currently best coach type in india, with various European Train models. But this method proves no help to me. I'm trying to work myself on modification ideas of the coaches, however, due to limited time find it quite frustrating. Anyways, thanks for the video.
