3 Side View of HWH WAP-7 30372 which was the Charge of Dn Kalka Mail today standing at PF No: 14 of HWH
4 Siemens 3-Phase EMU Rake of Eastern Zone Captured at HWH outer.
5 New Shining LHB Rake of Chennai AC Premium Exp standing at SRC Yard.(It was 3 AC Code:LWACCN). The entire rake of this train is mixed with Duronto and Raj liveried LHB Coaches.
6 BHILAI WAG-9HI 31400 with a Freight Train captured at Andul.
My Conversation today:
I had a "Brief Chat" with the LP of HWH WAP-7 30369 the Loco in charge of DN Coal Field Exp today regarding "Regenerative Braking" as soon as he "Step Down" from the Loco and stop the Train by pushing it's Brake. I introduced myself as a "Rail Enthusiast and fan of 3-Phasers" and inquired him whether it is "Regenerative Braking" which he has just used to stop the Train ? He said "Yes. It is Regenerative Braking ." I also inquired him whether this Loco is GTO or IGBT Technology built?
He said it is a "IGBT WAP-7" and IGBT System is more user friendly than GTO with regards to Trouble shooting of 3-Phasers. He was in a hurry to release his duty formalities so I let him go without sparing his time more.(I can't Capture WAP-7 30369 as all LPs and Rail Police are there at PF-12 of HWH. Sorry for that)
I had also a "Brief Chat" with one of the LP of Electric Locomotive of South Eastern Railway today who catch our train(Midnapur HWH Emu) from SRC. I also introduced myself as a "Rail Enthusiast" here and inquired him whether SER will take "WAP-7" in future ? He straightforwardly said "No" for some reason best known to SER. Then I asked him now when these WAP-4/WAM-4 etc will retire and Conventional Loco Production will stop then what SER will Do ? He said "SER knows it best"and also agree with me that "SER is a Stubborn Zone towards 3-Phasers in spite of its advantages."
My Observation:
In SER now most VSKP WAP-4s recently turned out from CLW with AC Cab fittings like 3-Phaser are used with most of the trains like East Coast Exp, Puduchery Exp etc. These WAP-4s have cab lights completely identical to that of WAP-5/WAP-7 & WAG-9.
The entire Rake of Kalka Mail is "Bio Toilet Fitted" observed at PF 14 of HWH today.
Many "Bio Toilet Fitted" ICF Rakes are seen at many Stations of SER today.
WAG-9 of LGD,AJNI,TKD, BIA frequently seen in SER with Freight Trains.

Re# 1612710-31              
diesel EMD's can't shut EOG's/Self generating units completely, only supplement them. kind of like how Solar PV cannot provide complete electric supply of home but rather does so with the help of grid supply. It needs along with regenerative system (which means active front end rectifiers) a voltage sensing device which can decision based on whether to put load on EOG/generating unit or draw from loco. a challenging task, but not impossible.
for 3 phasers they simply take power from OHE and supply it backwards.

I only talked about 3 phasers with HOGs abilities Sir..........they can definitely take up the load of the EOGs, as they take power directly from the catenery!

Dear Sir,
Thanks for the appreciation which has been the "Mental Boost" for my work here so long. I have already shared my "Conversation with the WAP-4 LP of SER" and also the Reply made by Him. As per the Logic SER can't be judged which is easily reflected from the reply of the Lp. However, now the WAP-4 count of SRC is going to nearly 80 additionally AC Cab fitted new WAP-4 from ET, VSKP, RPM etc now regularly visits SRC these Locos will fulfill the Coaching requirements of SER till 2060. So, SER won't require any WAP-7 I think. Another fact which I think after posting Entry# 1614043 today that SER probably have no "A" Category drivers and Loco

Inspectors who can teach Crews and Shed Staffs about 3-Phase technology. Whatever is the case it is sure that 3-Phase Coaching Loco won't be taken by SER and ECOR too.
Next Time I will definitely try to get the information as sought for.
