Let Bezawada - Gudur get tested n cleared for 130 limit, similarly, let Secunderabad - Kazipet - Bezawada get cleared for 130 limit at least.
Tests were done only in Secunderabad - Kazipet - Ballarshah section, but there is no results nor any progress.
Present day infra isn't sufficient for Shatabdi class train to run in this section. A lil upgrade is enough, then Board/SCR can think of a Non stop one.
