How Do I get the maximum refund now? If I file TDR now, I will only get 50% refund. And it seems the train may not be more than 3 hrs delayed at Bharuch as it has some slack time before Surat where it will make up some lost time, so waiting to file TDR for train delayed by more than 3 hrs may also not give result. Also I have changed my boarding point from Surat to Bharuch, For purpose of filing TDR, timings at which station will be considered?
