My daughter happened to book 3A for this train of 28th March, from ALD to ANVT last minute. As a first timer on reaching the ALD junction she absolutely had no clue about the platform no., coach position, that it runs combined with 12487, actual arrival time - no displays, no announcements, and so on. INQUIRY window had a long queue, no rail-staff accessible for correct info. At last a kind cop helped her with revealing the secret that 22487 is the section of the 12487, may be tailing it, to her great relief.
