Travelled in this train in AC 2 Tier (2A) from Thane to Kanpur Central on September 18, 2022.
The coach position for this train has been incorrectly displayed on this site, as well as on Where Is My Train. In my personal experience, the coach positioning for Sitapur bound 12107 was as follows -
Generator→...
more... One General Compartment →Sleeper coaches (S1 to S12) → Pantry Car (between S11 and S12) → AC 2 Tier (A1) → AC 3 Tier coaches (B1 to B4) → One General Compartment → Generator
Waitlisted passengers have a good chance of getting confirmed ticket in this train (at least for AC coaches). Plenty of tickets were available in current booking for 2A and 3A when I boarded, and still many passengers get down at Bhopal.
Although this train has been extended to Sitapur Jn, almost all station announcement systems still refer to this train as Lucknow Express. I mentioned this just in case any passenger gets confused on platform.
