I think its RSA with 02171/72 CSTM-JAT AC Special has been restored back. Today the 17+ hours late 02112 LKO-CSTM AC Special was short terminated at Dadar and 02171 is rescheduled to depart at 16:40 (09:55 hrs late).
.
Now, either both of them are using ICF rake or are using LHB rake. Anyone has seen both recently?
