2138 leaves Jhansi at 12.35, 20 minutes before 12804, and arrives at Bina Junc. at 14.50, still 20 minutes before 12804.
Therefore it seems unlikely that 2138 waits at Lalipur to be overtaken.
2138 leaves Bina at 14.55 and arrives at Bhopal at 16.55. 12804 leaves Bina at 15.15 and reaches Bhopal at 17.10.
