The station of T-Sakibanda lies between Guntakal and Ballari. It is in Anantapur district of Rayalseema region of Andhra Pradesh and close to the Karnataka border.
Note the peculiar spelling of T-Sakibanda. Not like the better known Tsunduru elsewhere in Andhra Pradesh. The hyphen after the T is clearly shown in this sign for all three languages.
Even the local map does not throw light on this:
Could it be a word like Tehsil or Taluk? Such words would normally be spelt out in a place name (e.g. Tahsil Bhadran, Kasur Tahsil). Anyway, in AP we have divisions and mandals.
From Google we get another T Sakibanda in faraway YSR (Kadapa) district. This has an alternative spelling of Chaki Banda (just like Chunduru for Tsunduru). Perhaps that is the explanation. But why the hyphen? Was someone fond of T-series cassettes or perhaps T-bone steaks?
