sir, Emergency quota is released 2daysbefore the scheduled departure of train. One has to put an application to Chief Commercial Manager of the particular railways zones.In every train and in every class there are certain seats categorised as Emergency Quota. It is the nomenclature of the Quota. Allotment is based on specific requests. Priority & allotment is decided based on clear-cut policy guidelines.A recommendation by MLA, MP, Medical person on your application might carry little more weight and even if you know higher official in railway will also definitely give you advantage to get you in emergency quota.
