Hello everyone
IN recent last few weeks i continue track the Tatkal booking data of the Following trains
(New Delhi / Nizamuddin to Ernakulam/ तिरुवनंतपुरम)

Train nos are as...
more...

follows
22656 Nzm - Ers superfast Exp
12644 Nzm - Tvc Swaranjayanti Exp
12618 Nzm - Ers Mangala Lakshadweep Exp
12626 Ndls - Tvc kerala Exp
22634 Nzm - Tvc super fast express

what I found that
12644 is the train that doesn't full fills tatkal qouta ..
even this train has lots of tatkal tickets available 😀 end to end from last 4 weeks continue every Thrusday I check the tatkal booking data of these trains I found
12644 has plenty of vacant berths in TQ qouta

passengers prefer
22656 - 12626 - 22634 as priority 👌 their booking done within 3 - 4 minutes of tatkal booking opening
where as
12644 still today Available berths

why this train is not preferred by passengers ?.
