Actually reversal at TCR is technically difficult for a train of more coaches i believe (kindly correct me if I am wrong). PF 1 and PF 2 are mainline platforms which cannot be blocked and one loop line for smaller PF 3 and one line for goods/departmental use is there I guess.
.
Moreover, CBE/TUP/ED does not have a proper dedicated overnight bidirectionally for bengaluru and they rely only on passing by trains, that too has very less quota for CBE/ED/TUP and timings are not convenient as well. Pls check for...
more... daily trains in that stretch 16525/16527/16316. This demand is existing for AGES. so let it be till CBE only.

16525 atleast has GNWL for TCR. TCR is well connected for GUV. If you come outside station, lots of buses will be available which takes 40 mts to guruvayur or
/chain/27292 this daily combo is very much available.
