SR is one of the top zones interms of number of passenger trains run by the zone. Railway employees recruitment is not under the control of zone and it rests with RB approval.
Lack of employees has been in SR for quite a long time and now its turning ugly due to no special run by the zone in the recvent past say Pongal/Summer Vacation.
Could be SR is in protest with RB for non approval to recruit employees. Even to recruit Khalasi in ICF it needs to come from RB.
