Now Python rakes will rake on BKI AF section also
Tender Title Signalling work in connection with provision of longer loop line at Kitham Station (Mathura-Agra Section) and at Ghosrana station (AF-BKI Section) for running of Python Trains of AGC Divn on N.C. Rly

Well, my explanation was for a freight train only , and ideally, cannot be extended to passenger rakes just like that. The main advantage with python rakes is that in most cases there is absolutely no need for any shunting operations. The front portion detaches and goes on it's wy while the rear portion continues on it's route. This can be even done with just a single long loop line, without blocking the mainline.
Passenger rakes will need much more, as they will not be run with a loco sitting idle in the middle. So they have to be shunted, and this will require a larger yard. I can think of the following problems with your proposal....

2) Logistics : Even if a yard like that materializes, then there is the issue of safety and managing operations. The train will have to enter the yard at a reduced speed, wait for 5-10 minutes for the shunting operation, and a few minutes for doing the brake testing for the combined rake, and again waiting for clearance on the main line before proceeding out. This will eat up close to 20-30 minutes in most situations. And I am sure passengers will not appreciate their train being shunted about in some random yard for half an hour, just after their journey starts.

Now let me tell u the operating reason apart from these why coaches cant simply be coupled /decoupled right in the middle of the journey.. Let for our case assume that the stn choosen for attach/detach in HBC chordline is BRPA approx 24 km from HWH & 71 km frm BWN.let say a 15 coach train starts it journey at 7.10 frm HWH crosses DKAE at 7.29, JNX at 7.34 to reach BRPA at 7.41. In this process it overtakes a freight at DKAE & JNX which waited for 19 mts each at respective stns to get overtaken & commence their journey at 7.37 & 7.44 respextively. Our Exp after addition of Slip coaches restarts its operation at 8.05 frm BRPA but by the mean time both the freights have moven further forward & again they need to be looped at CDAE at 8.17 & BMAE 8.23 for reovertake by the...

That is exactly what I have been teling about Python rakes. They are not used for short runs. Python rakes are typically used for long stretches of 200-400 kms. And in addition do not jumble up the operations of a python rake with that of a passenger train with slip coaches. Both are completely different scenarios. A passenger train with extra coaches is still a single train. But a Python rake is essentially two 'separate' trains.
And no, there is no time wasted for a python rake in the yards. This is how it works.

In WR two rake of Concor runs as Python and many times I m seeing it at Surat before Pune Duronto/TvC Rajdhani and it not allowed to OT it before Surat and it run non stop BRc to Udhna (not sure where it was looped for OT)
