Apart from DG unit in EOG coach, there is also brake van part and train manager (guard) compartment in the same coach, so even if Railways want to remove DG units they cannot do it so easily as the brake van and train manager compartment would still be required and it will be a waste of money to remove those DG units and rework the design of the EOG coach.
Vande bharat jaise EMU me multiple pantograph power se connected hote hain aur unme light, ac, socket, vacuum pump (also called hotel load) ke sath connection diya rehta hai. Isme ek panto agar power se disconnect hote hain, toh dusra pantograph se power continuously aata rehta hai. In traino me ek auxiliary converter hota hain, jisse jahan jitna voltage hona chahiye utna supply kiya jaa sakta hain. Like AC ke liye 3 phase AC 415 Volt, water pressure boost pump ke liye v same 415 V aur light aur laptop charger point ke liye 110 V DC lagta hain. Lekin sare light, ac etc ka electricity connection parallel me sare converter se kar diya jata hai. Taaki ek converter band hoga to dusra power deta rahega. Is vande bharat me sare panto ko sare traction transformer ke sath lage hote hain parallel connection me, ek set of vacuum circuit breaker ke through, jinhe DJ ya disjoint v bolte hai, taki hotel load continuously milta rahe. EMU ya MEMU me kuch kuch chize kam hote hain.
Agar bijli chali gai to multiple pantograph kya karengay. Public kya garmi me maregi band coaches me. VB has batteries mounted below the coaches just like traction motors. They will keep powering fans and lights in case of electric power failure.

Train ki speed 120KMPH mane To 1 minite me train 2 KM chalegi And 1 second me 35 meter 50-100 meter ka section bhi without electricity hoga To max 3 second ka hoga light off
Vande Bharat has multiple pantograph ;so if one coach has neutral section others wouldn't be in neutral and this coach will is provided electricity by other pantographs HOG
some battery units can be placed inside the locomotive, or under coaches so that a limited amount of power can be stored and supplied so that the need of EOG can be replaced permanently
in old ICF coaches, all fans and lights would be of 110v dc. and we as kids would joke that railways used 110dc to prevent them from being stolen and used at home. fact is, there is a bank of ten 12V batteries , usually lead acic batteries which means they created 10 x 12 = 120 volt dc. there are two bank per coach, each charged by the alternator connected to the wheels. but all this creates a drag on the locomotive as the locomotive not only has to pull the coaches but also provide enough momentum to maintain speed despite this drag by alternators. this is why ICF coaches are rated at 110km max. LHB coaches on the other hand have nothing connected to the wheels, so those coaches can achieve and maintain higher speeds but now electricity has to come from either EOG or from HOG. i am not aware if they have any battery banks underneath, i have noticed only brake pressure tanks, no batteries beneath LHB coaches.

VB doesn't need EOG because of multiple pantographs same as locals and MEMUs

15 second k liye batteries backup nahi de sakti kya?

newer EMUs are powered from wires, havent noticed any bulbs ,

Kya LHB coaches me wheels pe Dynamo nahi lagaye jaa sakte.??
Possible but it will increase its weight and will reduce the speed
Aur maintenance cost bhi jyada hai
अच्छा समझाया आपने

Very good vibes
Jaise vb me eog nahi hai waise hi agar hum zayada trains push pull mode chalaye to bhi hame same reason se eog un trains me bhi nahi lagana padega
kya hum LHB ko modify karke dynamo add nhi kar sakte?
