CAPE MS SF was having RSA with Island once upon a time. TN people hated it cause Island arrival at CAPE is always late and that delays the prestigious CAPE MS SF. Also its maintained badly cause PM is done only every 3 days. So people complaint raised a lot which eventually before they converted the rake to LHB , they cancelled the RSA and CAPE MS SF started to have RSA with Pearl City and Island stand alone rake !
I think its extended to kochuveli cause it stands idle...
more... in Nagercoil for more than 11 hours. Not going to delay Seshadri cause of its extension cause its just 75 kms. But SR/SWR needs to come up with their own set of rakes instead of using SCR rake. But defnitely not Island again lol.
