for the train 12162 lashkar express from agra to LTT, the admin note says
Train is in RSA with-1.Lucknow LTT SF Exp (12108) 2.Udyog Nagari Express & Habibganj LTT Exp"
My enquiry is how id RSA (Rake shared) executed, i mean how it is done, why it is done, and is it a advantage /disadvantage for a traveller
Thank you
Manish
