Great effort. a small doubt though, KYN ELS seems to be isolated DC section, how do WCG2s move in and out in this case?

recently when i visited mumbai, i saw a track under 25KV AC which emerged just after kalyan beyond the slow down track. the AC track then multiplied and went on the rightside. can anyone tell where does that line go?

They will be towed by either Diesel's or Dual-currant Electrics to the shed, the same way the AC Bankers of the Thull Ghat region are brought to the ELS for maintenance.

Thats a great effort.

Thats a great work. Just a small correction. At Virar there is no connection between the through and local lines.

any idea why KYN Shed is pure DC as it also holds WAG-7s used for bankings
I thought that it was AC-DC shed as both pure AC and pure DC locos are homed here?

KYN shed is surely not under DC wires. I am sure it is under AC wires, with just some lines dedicated for DC locos. It makes no sense to keep the shed in DC, since it is now bound to get more AC locos. In any case, the number of DC locos are on the decline.

Please check if there are any neutral zones around the entry to the shed, on your next visit.

Great effort surely Vijay! Just one doubt here as per the map trains bound for ADI from PUNE will compulsarily have to take 5th (or 6th) line between KYN & DIVA to branch out towards Vasai else they will have to reverse at DIVA which is not the case. There has to be another connection and neutral zone near DIVA for traffic coming from KYN anf going toward Vasai Road.

Can anyone throw some light?

Please keep up the effort and keep updating this image. Nice caption. Slowly but surely WAPtors will make the WCGs and WCAMs history.

WCAMx esp WCAM2/2P/3 and WCAG1 will be around for another 15 years or so...they're only a 10-12 year old specimen. WCG2's yes sadly will bid farewell.

Thanks everybody. Please find the replies:
1. KYN ELS: At the gate of this ELS where a single line enters ELS, A very big board on the OHE right above the line reads "AC Territory ends, DC Territory starts". I couldn't capture it on my cell due to presence of RPFs Hence ELS gets isolated & is under DC traction. However inside ELS, there are seperate AC & DC lines to test the AC / DC / ACDC locos.

2 things CR could have done further: Convert entire ELS into AC as also Diva Jn PF 3,4,5 & loop lines & place neutral zones just before entering Diva Jn from CST side. By this CR could have started Diva-Vasai/Panvel MEMU services. Inside ELS as of now, both DC & AC locos have to be towed dead into ELS which isn't making sense at all. On the conversion day we spotted 3 WCG2 dead near ELS gate perhaps to be towed & places onto the DC lines.

2. Virar: I guess, the older DC lines have nautral zones before they merge onto the new 3rd & 4th lines. Previously the older lines used to be...

2. Virar: I guess, the older DC lines have nautral zones before they merge onto the new 3rd & 4th lines. Previously the older lines used to be straight lines with 3rd-4th lines emerging out of them but WR re-aligned them to make the 3rd-4th lines straight. Pls correct me if my understanding is wrong.

3. Diva/Kalyan - Vasai: After Kopar stn facing towards CST, a pair of lines branch out from 5th-6th lines and go to Vasai, and at the same time, a pair also branches from 5th-6th lines from Diva side & both pairs merge and go to Vasai, hence no need for ay reversals for traffic coming from either ways. Same is the case for PNVL bound lines. Neutral zones is on the Diva-PNVL pair as well as on 5th-6th lines immediately after Diva Jn outer as shown in the pix.

4. In all if we see, we have 7 neutral ones on CR & 2 on WR isolating the DC & AC tractions at various locations.

I appreciate your patience and efforts in making this diagram.

Vijay, at Virar the old DC lines DO NOT merge with the new lines. They hit a dead end at Virar.

Thank you so much Apu Sir.. :-)

Akshay, I remeber, there were 2 DC lines ending at Virar for EMUs & 2 AC lines starting from Virar for MEMUs. But what about the main lines which continued beyond & had a neutral zone alongwith the newly constructed 3rd-4th lines? I have tried to refer to them only in my pix. As of today, I think, there are 4 lines which must be passing through Virar- 2 being the old ones & 2 being the new ones apart from loop lines if any.

Great diagram.

Any idea by when the Pune - Karjat - Vangani section would be converted? There was an article in Dec 08 that the conversion work in this section is almost complete.

The SSPs and substations have already been installed in this section.

Vijay, what Akshay is saying is right. The track layout at Virar has changed in the last year. The DC tracks end in a dead end. The 3rd & 4th AC lines continue as the mainline towards Vaitarna with loops for PF5 (no Neutral zone here). Also the MEMU lines end in a dead end to the north of the DC dead end (station building in between).

Thanks Jitendra Sir & Akshay for the revised layout explanation on Virar. The same has been updated & re-uploaded.

Moderators: Kindly delete the old layout.

Grt work Vijay. This diagram will help me locate the new neutral zone easier

Saw other Post by Vijay that seems to indicate Pune KJT are under AC wires now as of May 3rd, 2009.
Question:
1] If that is true or when that happens, who is going to do ghat banking duties
and
2] Are my WCG2s out of the job then ? (We dont need the DC shed then)

No Mandar,Pune-Karjat is still DC.The main proof of this is the DC EMU's which still ply on the Pune-Lonavala route.But AC traction will enter on this route definitely by the end of this year.
