Not sure about that, trains like 12601 and MAQ ICE, reached 1hr late at MAQ, in that 1hour, 30 min been was added between SRR-MAQ section. As told before, Parasu, only 20min was added in that section. So not exactly sure whether it is because of TSR or other issue.
May be if someone travels in that section, it will give better idea. NTES can't be treated blindly, they might say train has reached on time, when it was late by 30min
