Duronto gives 73 kmph average non stop.
Howrah Duronto runs like a Real Rajdhani non-stop giving lesser run time or more average proving a non stop rajdhani alike run, actually helping to give better average.
Same in IGP BSL 110 kmph mps section...
22109 LTT NZM IGP-BSL 90 Kmph average one halt
12289 NGP Duronto IGP-BSL 88 Kmph average non stop
12261 Howrah Duronto IGP-BSL 88 Kmph average. non stop
so these so called lines of so called High speed zones that SF hai Rajdhani nahi... it is not necessarily applicable in other zones like SECR n CR.
Sadly, 22110 fails to maintain the timings coz of so called high speed zones.
BSP Rajdhani doesnt have a complete different route , LTT NZM shares the same timeslot as BSP Rajdhani in ET-NZM section.
comparing the remaining sections, BSP Rajdhani NGP-BSP section average speed 63-66 Kmph @110 kph mps fully while LTT-NZM ac exp in LTT-BSL section 69-73 kmph @105 mps (LTT-KSRA) and 110 mps (IGP-BSL).
so forget the tags and FOLLOW THE TIMETABLE. Improve the punctuality increase the frequency and then make such demands.
