Monday evening, we'll be in Chennai and then heading to Kanyakumari. On Tuesday, we're going from Kanyakumari to Bengaluru. Then on Wednesday, we'll be back in Kanyakumari. On Thursday, we're making our way from Kanyakumari to Chennai. And on Friday evening in Chennai, we'll need 4 rakes. If it's connected with Pearl City, then the cycle will start from Tuticorin with PM and SBC as SM with 6 rakes. Currently, it's being maintained in Tuticorin.

You can do SM anywhere at SBC or CAPE. Looks like these 3 RSA are possible.

The arrangement is not good at all, it's a mess. The Island Exp rake at CAPE could be used for a new overnight service now that MDU-NCJ is not working anymore. There's also a smarter option to use Island's rake for operating 17235/6, which would free up Seshadri's rake at SMVB to run a different service. If SR wants to take over Island and bring back the not-so-popular RSA with 12633/4, they should do it and relieve Pearl City (they can make up for it by introducing a new train or increasing the frequency of one of the trains from MS) as well as spare Bangalore CDO from secondary maintenance duties.
