The same is the case with HWH and BBS Duronto as well, my friend. I saw NCR's DRM twitter handle saying that 12260 SDAH Duronto gets delayed due to suburban traffic. Yes, even i was unable to understand what he wrote. Many times Railfans from West Bengal have questioned and complained on twitter. All we can expect is that Railways is keeping this on mind and will make amendments in time table for the same.

Just see 12260 run from Ndls to tundla. While rajdhani cover the stretch in 2.5 hours. It has to trail the evening suburban passengers to aligarh and tundla. It takes 3 to 3.5 hours. Then 12560 keeps trolling it due to which it is always 1 hour late at CNB. Even post CNB it follows 12560 upto ALD adding further delay. Post that same delay time is maintained upto Sdah.

Based on my tracing experience, 12560 starts trolling it post Panki/Kanpur. Bacause there have been instances when i saw Duronto crossing Tundla and SG near Balrai, difference of almost 70 km. Anyway, everyone knows the priority SG is enjoying these days. But yes, the GZB-TDL stretch is really disturbing. In fact, Duronto takes 2 hr for ALJN itself.
