Poorva Express: हुगली सी बहती तेरी चाल है पूर्वा तू बेमिसाल है - Keshav Singh

We all know that 12802 NDLS Puri Purushottam Exp is hauled by WAP-4 from KGP to PURI.
Now like all of you I have also a Curiosity why WAP-7 can't be provided end to end with this Train. Today found a "Significant Information" from E-Loco which is the "MAIN REASON" of it and I described it here.
Date of Incident: 01st Jan 2015

No: 12802
Incident Type: Direct
Detention in Minutes: 30
RLY: SER
Division: KGP
Loco: GZB WAP-7 30228
Brief Reason: Train detained at KGP station after power reversal for LP having no handling of 3PH loco, Fresh conventional loco provided, poor planning by crew booking staff.
Finding: Train was abnormal late due to resheduled and incoming loco was programmed to work the train up to PUI. LC/ADA & KGP had pre-intimation that 12802 Express was coming with loco-22334/GZB, but working loco was 30228/GZB. LP/KGP(D/C) refused to work WAP7 loco as handling of WAP7 loco not provided by Mech. Dept. even WAP7 is running in the system since 2 years.
Classification of Detention: Crew/Loco Operation
So, from the above incident of 1st January 2015 it can be easily seen that Crew don't want to handle WAP-7 loco from KGP to Puri. Though WAP7 is running in the system since 2 years. This is the reason why 12801/12802 Purushottam Exp is not allowed WAP-7 from KGP to Puri and Vice Versa.
Just see the YELLOW COLOURED ROW in the attached screenshot of the Excel Spreadsheet.

Hat's off to the Loco Staff. Die hard fan of WAP-4.
Please note that ALL LP's of ECOR have already completed their 3 Phase Training at LGD ELS like SER and SECR and Kalinga Utkal Exp is a train which goes to Puri with WAP-7 DAILY.
