Extensions done for the sake of it has really been a bane in case of SR.
The 12795/6 (since then taken by a different train LPI-BZA) SBC-MAS daytime service could have still materialized had they formulated a RSA between 17603/4 and 17651/2 but now the latter is mindlessly being run upto PDY just because of its RSA with Circar.
