Earlier there used to be a restriction on the maximum distance trains could be run without toilet facilities. If I remember correctly, this was 150km. Though many exceptions to this rule exist now (and existed back then as well), the rule is still followed in setting the schedules for some trains. That could be one reason for splitting a single service into 2 nominally separate services. Some MEMUs on the VSKP-RJY-BZA-OGL were also scheduled this way. This also lets them make a small amount of additional revenue by exploiting the distance/fare particulars.
This may not be the correct reason, but its as good as any other guess.

06511 vs 06551 -- i thnk 06551 will win the battle! ;-)

---

06551 is best because of new LHB rakes, but it will discontinue as the rakes belongs to 22685/6 YPR - PUNE - NZM - CDG biweekly exp, and it has to start. Where as 06511 is having idle rakes of GR and it is long running GR, record braking performance for 3 consecutive year, most reliable/punctual spl train, cleanliness at it best.
We can consider 06529/30 as good contender with 21 coaches idle rakes, and can be made permanent, in coming budget.
