What ever the timings are both of them will run on tracks only and AP will not fly. This forum is to share ideas and discuss to about railways and please don't put such posts. Trains will be run according to priorities given by traffic pattern on that day of run and clearances of timings given by Rly board. They may be fast overtaking all scheduled trains or may be trolled depending on freight movement and other trains. AP has got good timings which is everyone wish and we should be happy with them.
