I and my friend Amogh Joshi had made a monster train which runs on single phase 230V AC source and the rated speed is 2500rpm. It was supposed to present on a event in our college named 'Track-o-Motive'. But at the time of performance we get some technical problem in it and the wheel were not touching the rails, which should thouch it for taking power from the source. So we did not get selected for the second round. But really want to thank those peoples who have helped me either for making such a good thing.
