@akshaywcam1 At times, drivers do this deliberately while trailing a train ahead. He slows down well in advance in anticipation that the train ahead will continue on its way and allow the signals to pick up aspects.
The net benefit is that he avoids the need to come to a dead halt!

@saurabh5620 Since the interchange at Saphale was commissioned, container traffic on WR has declined substantially and may come down to very low numbers after proper commissioning till JNPT with only the WR terminating/originating trains at Boisar, Karambeli, AKV, etc being seen.

@saurabh5620 CRS grants sanction for running passenger carrying trains when he is satisfied that the "Rules For Opening a Railway for Carriage of Passengers" and other relevant manuals are substantially complied and subject to the issue of a Safety Certificate by the Railway concerned.

@bhaumikgowande Indian Railways have been using such old converted coaches for carrying light freight for decades now.

@oracledarlings Rakes carrying various company names are actually for the electrical power and control systems of the trains such as the power collection, transformers, controllers, traction motors, ventilation, etc.
The shell, seating and furnishing is done seperately by the PUs such as ICF.

@Ananth_IRAS ... difficult due to cramped layout.
One option may be to entirely eliminate the freight line connectivity and handle all activities related to freight at some other location.

[Khalid Kagzi @TapChanger]

@Ananth_IRAS Only 2 lines are important over this diamond crossing while the other 2 lines are for trains from ET side to enter the freight yard.
Ideally, there shud be some strategy to dismantle this layout so movement can become efficient and speedy.
But it will be difficult due to...

@Naveen091105 @Ananth_IRAS Compared to that, with twin-locos hauling from front, once the formation is stretched out just after the train has moved a few meters, these locos can accelerate at the same rate as PP, the twins can be attached to any train, no circuit to maintain and easy shunting.

[Khalid Kagzi @TapChanger]

@Naveen091105 @Ananth_IRAS PP is marginally better but the hassle is more in maintaining the circuit throughout the train, deputing an asst in rear loco, even minor issues with the connectivity resulting in rear loco failure, operational issues like shunting and lack of flexibility.

[Khalid Kagzi @TapChanger]

@Ananth_IRAS If IR could sort the supply of resilient coupling, it would be a good idea to restart production of the WAP5s in twin-configuration like the WAG12 or the WAG9T with single panto operation and HOG arrangement.
This would be a terrific combination to haul high speed trains

[Khalid Kagzi @TapChanger]

@Ananth_IRAS As of now, the WAP5 is a misfit in the overall scheme of things, since most trains are becoming longer and heavier and the WAP5 has to spend more time in achieving target speed as compared to a P7.
This is the reason it is now being utilised for the AB trains in PP mode.

@Ananth_IRAS @ThereIssNoSpoon Sir, regenerative braking is modern technology. Every 3-phase loco, VB trains and 3-phase EMU/MEMUs use it to reduce speed and feed energy back to the OHE.
It is not an old tech but there might be further scope for increasing its efficiency.
Possibly, you mean dynamic braking?

[Khalid Kagzi @TapChanger]

@Ananth_IRAS Semi-permanent Scharfenberg type couplers have been in service since many decades in suburban EMUs running in Mumbai and other places.

[Khalid Kagzi @TapChanger]

@jarvik @gbenhur Yes, such restrictions exist where there may be a sharp turnout (1 in 8.5) or due to sharp curves.
In both cases, passenger trains are restricted since they have much longer wheelbases, as compared to freight wagons.
The length puts more torsional stress, thus the restriction.

@brahmmajoshi You are a subatomic particle, not human.

@NorthOdishaRail @Ash18537355 These are temporary bogies, fixed to move the coach around in the factory.
Eventually, it will get a proper Fiat bogie as used in the VB trains.
