By pairing the 12657/58 a prestigious train with 12627/28, the train no 12658 is leaving most of the times 3 to 6 hrs late from SBC. This is due to late arrival of 12628 at SBC.

Earlier this problem happens during winter due to Fog in North, but now it is happening during Summer (as of May 27th, 2018) also. We don't know the exact reason.
Even when the train arrives SBC around 18:00 or 19:00 hours also, they are taking the train to yard and do maintenance for six to eight hours and then only starting to MAS.

Instead, they can do the maintenance at station itself (like 17210 /35) and do the complete maintenance at Chennai (where the train is held for about 18 hours). By this way, the train can start SBC in time and reaches MAS morning. The maintenance can be shifted from SBC to MAS.

Railways has predefined maintenance schedules based on the type of rake and distance rake has travelled and rakes home base. In general ICF rakes are taken for primary maintenance after 3500 kms. Before 3500 kms, a rake can undergo either secondary maintenance or platform turnaround.

In case of 12627/28/57/58, the rake has the following schedule for maintenance

12658(360 kms) - 12657(360 kms) -12627 ( 2410 kms) - secondary maintenance at NDLS - 12628 - Primary maintenance in SBC . Primary maintenance requires about 6- 8 hrs. Since SBC is the base for primary maintenance, the train has to be taken to yard, inspected and cleaned up before going out as 12658.

In case of Seshadri / SBC NCJ express total distance travelled is less than 3500 kms. So platform cleaning at SBC is sufficient

OK.
Can anyone tell what is the reason for frequent (almost daily) delayed arrival of 12628 at SBC even during summer, while the opposite route 12627 is running almost in time.


Also when one expects primary maintenance of 6-8 hours, why Railways has planned only a 9 hour halt between 12628 Arrival (13:40 hrs) and 12658 Departure (22:40 hrs) at SBC.

While linking the two rakes, they should have planned a time schedule in such a way that 12628 arrives SBC by 10:30 and 12658 leaves SBC at 22:40 (Same Departure time @ SBC for 12627 and @ NDLS for 12628 and journey time same).

What we all wanted is the train 12658 should be operated on time and not odd hours

1. Maintanence had been neglected in order to run more trains post 2004. After 2014, maintanence backlog has been taken up. Hence trains are getting delayed.
2. Double line is getting commissioned between Bhigwan and Kalaburgi in phases. When block for interlocking happens, trains get delayed.
3. Manmad - Daund is single. 12628 losses time in supercongested New Delhi - Manmad section and enters the single section late. Hence it gets looped for crossing with ontime trains causing furher delays
4. In Bhigwan - Kalaburgi section, a delayed KK has to face crossings with trains bound for Mumbai. Mumbai trains that get delayed are looped at various stations, as suburban trains have precedence. So Mumbai bound trains are cleared first in order to avoid bunching in Mumbai region.
5. When KK enters single line after Dharmavaram, it is looped to allow trains coming from Bangalore.

As far as 9 hr between arrival of 2628 and dep of 2658, if 2628 is on time this is sufficient. There are many other trains in addition to 2628 that get maintained at SBC. Each train has a slot at pitlines. Plus shunting operations are involved to remove rake to pitlines and to place it in the platforms, movement of light locos to get coupled to 2658 and after decoupling from 2628. SBC being saturated, its not easy to get new slots. The time you propose would need change in timing of 17236/17209, 18463/4 and other trains from MYS side.

When more and more trains are getting operated, maintenance / yard facilities should be increased at all metros. The ideal thing should have been maintenance of this train at MAS and NDLS instead of SBC.

Does it mean the train 12627/28 and 12657/58 are totally delinked or only on the days when 12628 arrives SBC late.

When I travelled from MAS to SBC on 7th June, I observed that train has the board of both Karnataka Express and Mail with their corresponding numbers. Also there was a Pantry Car ciach in between which will be used only when it is running as 12627/28. But when I checked web, NTES says on previous day (6/6), 12628 arrived SBC at 18:30 and 12658 left SBC at 22:40.

The question is whether 12657/58 is totally delinked from Karnataka Express or an additional take of the pair has been made.
In both cases, train 12628 halts at SBC for more than 24 hours

There was a spell mistake due to auto correct. Please read the phrase 'additional take of the pair' as 'additional rake of the pair'

A scratch rake is being used. THis rake runs as YPR BGM special on weekends. So in weekends 8Mail gets late, if KK gets delayed.

Good news on the above front.

But one point: 2658 mail has RSA with 2627/28 Karnataka exp. So does this mean that 2627 will also run on AC traction? Or does this mean that either the RSA with 2627 is coming off and/or 2627/28 will run on conventional rakes or partially with conventional ICFs? Any take on this Rajagopal?

Just today only (after 4-5 days) I saw 2626 Kerala exp. being hauled by an ED P4 but with its (first or second) LHB rake. On the earlier occasion, it was the ICF 2625 which was crossing CSB just before entering NDLS.

Yes sir. SWR proposal has marked 6 rakes for 12657/58 SBC Mail. Which means it includes KK also. On links, KK seems to be back on Diesel traction from SBC.

Atleast now, SBC Mail must be delinked from KK and removed of the pantry car which is useless for SBC Mail.

Cheers,
Raj

KA Exp or KK Exp? Is KK Exp(SBC-CAPE) currently RSA with SBC Mail? Or You mean KA Exp RSA should be delinked with SBC Mail?

Rake sharing arrangement, Karnataka Exp and Mail should be removed since both trains are important to SWR. Mail is the dedicated over night between both cities. Pantry car in mail should be replaced with 3A coach, should be made 23 coach LHB formation.
