Lekin Saraighat Bridge jo ki NFR ki second largest railway bridge hai, river Brahmaputra ke upar... Woh toh steel ke hone ke bawjoot bhi full speed me guzarti hai, aisa bhi hota hai kya?
Please create a separate video regarding this or edit this video Sir 🙂♥️
Sir after12th baad loco pilot kaise ban sakte our kon se book study karni hoti hai plz es par ek video banaeye
Hume garv hai ki humari Indian Railways ki speed steel bridge pe aaram se 70-80 km/h se nikal jati like Golden bridge ( Bharuch junction), Sabarmati bridge ( Ahmedabad junction) , etc. Maine speedometer pe bahut baar dekha jab bhi meri train steel bridge pe se gujarti hai. Proud of you Indian Railways.
Bullet train runs at 350kmph on both bridges and land
Mujhe train se safar karne me aur sab jankari sunne me bahut achaa lagta hai aur sabse achi baat ye hai sir aapke samjhame ka tareeka bahut achaa hai aap kam samaye ke video me bahut achaa samjha dete hai 👍

Bht hi acchi Knowledge thi.. Thanks
Mere mann main bhi ye sawal tha..jo aap ke dwara iska answer mil gaya..dhanyawad
Hello amit bhaiyya mera questions yeh hai ki secr zone mai bilaspur our raipur ke beach mai jo shivnath river ka bridge hai ussmai train aapne full speed mai kaise nikal jaate hai
बहुत अच्छी जानकारी दी आपने
I feel there are also different kinds of steel bridges and my observations say train run through cantilever bridges moves with their normal speed and vibration gets distributed in cantilever bridge. In case of long girder bridge train moves slowly and in short steel girder bridge, the train moves rapidly.

I also think so.
sir mai janna chahta hu ki railway reservation counter wale etne purane keybord, monitor ,mouse kyu rkhte hai es per vedio banaeye
Nice information. Please make a video on different types of bridges in railways. Why some bridges have iron cover on them and some have nothing over them and are open?
Mera bhi same question hai
I also have the same question
Jo bridge iron cover wale hn unki weight bearing capacity uss cover ko include kar k bani h. Yaani kisi cheej ko vertical karne se wo jyada weight bear kar sakti h. Jin bridge par cover ooper nahi hota unke neeche yh structure hota h ya phir bridge ki length ek pillar se doosri pillar tak (span) kum ho toh na ooper na neeche yh structure hota h. Structure ooper banaana h ya neeche yh ground level se track ki height dekhkar tay hota h.
@@jagatprakashgarg1538 Thanks Jagat ji. 🙏
Depending on the size of the beam and the number of piers required, bridge model is decided. If it is decided that a long beam is needed due to lesser number of piers/pillars, then a truss is essential to distribute the load of the beam. For a shorter beam length, an ordinary beam bridge is sufficient to hold the weight up.
Very Good Information for Amit Sir. 👌✌
Bahut aachha jankari di aapne
Amit bhai kiya tikat weting ho to train me regrvesan coch me safar ker sakte he look dawon ke bad
Apki baat bilkul sahi hai . Par kuch railway bridge par train ki speed kam nhi ki jati h jbki wo steel structure ki hoti hai. Iska kya reason h???
Good information
Amit Bhaiya
Kahi kahi pe hume OHE wire ke pole main Double ya triple pole (Main uska naam nahi jaanta)jo wire se attach hota hai dekhne ko milta hai toh aisa kyu hota hai
Aur ek sawal ki jab sabko pata hai ki OHE wire chhune se log jal jate hai toh unhe avg height ke according height pe kyu nhi rakha jata jab ki aise corridor bhi hain jaha pole ki height jyada hoti hai
Amit ji namaskar
Mera sawal ye hai jab koi train apne destination se dusre destination par jati to mera sawal ye us train konsa locomotive lagega jase new delhi se chennai rajdhani train hai ise operate
NR division kar ta

Sir i have a doubt explain me what is the difference between TURNBUCKLE coupling and CBC coupling plz explain both are used to connect 2 wagons what are advantage and disadvantage
Turnbuckle couplings are used in ICF coaches. CBC are used in freight & LHB coaches.
Only advantage i see in Turnbuckle is that they give less jerks when train starts moving or when the train comes to a halt.
Amit sir Hi ? Amit sir ak Q. Hai uska anser dejye bandar to bhavnagar train kabchalu hoge khuch apdet ho to bataei or bandara to jamnagar
Sir Ap DRM ke post pr Deserve karte hai....
Maine Bahot kuch Sikha apke Video ae....
Hats off.....
Mai bhi abhi tak yahi samajhta tha ki, train kamjor hai isiliye speed slow kar diya jata hai 😊
Thank you Amit.
What about
1. Farakka barrage ( malda) : speed- slow,
2. Vivekananda setu ( Kolkata): speed- fast,
Opposite things happen in these bridges according to your explanation. Please clarify
Good point
बहुत अच्छा भाई ऐसे ही विडियो बनाते रहो
Amit bhai....plz vidio.....rajdhani duranto gareebrath jesi train bade station ko skeep karte time speed kam kyo kar Di jati h....jabki unko mein line s nikala jata h fir bi speed kam kyo....plz plz...
Sir Mera bhi ek sawaal hai kripya karke bataye Jo steel brighe mein Patti hoti hai aur uske patri ke Ander bhi ek patri kyun rehti hai
Amit ji yeah bataya nahi ki jaipur junction mein abhi bhi diesal locomotive ka use kyon karte hai?
very good
Very nice information 👍👌
Partially true... As there are good numbers of Steel structured bridges through which trains pass at their maximum permissible speed of the region.. eg Teesta bridge in West Bengal is a steel structured bridge (no ballast on the tracks) but trains usually run at 90 - 100 Kmph over it but again sometimes they cross at 50 - 55 Kmph. Same is the case at the Narnarayan Setu which is a 2.3 Km long bridge over the Brahmaputra in Assam. On the other hand Faraka bridge in West Bengal is a concrete bridge with ballast on the tracks but a train's speed while crossing it is about 50 - 60 Kmph at maximum.. Also it has been observed in case of many small Steel structured bridges that just before entering them a train is slowed down and once the locomotive and a couple of boogies enters the bridge the train accelerates and gather its speed while it is still crossing the bridge...
Farakka Barrage is a bit of an unfair comparison. It is not only a bridge, but also serves as a barrage holding back water (the struts are shared between the bridge and the dam), so to prevent overstressing the dam, the trains are slowed down.
The main discussion is a lot more nuanced, having answers in structural engineering and geography.
1. If the bridge is a truss bridge with the spans of the trusses being short, then it can handle high loads and high speeds, and vice versa. Same goes even for concrete bridges as well.
2. Another key component that many people overlook in these comparisons is the foundation beneath the pillars. If there is a solid bedrock beneath the riverbed silt, the engineers can firmly anchor the pillars to the bedrock, which makes the bridge much more stronger and capable of handling high speeds. Otherwise (for clay based foundations), the engineers are forced to use unconventional solutions such as spreading out the base of the piers and using pile struts to stabilize the soil, which limit the operational speeds compared to foundations on solid bedrocks.
3. Another technological improvement in the recent times (late 2000s), is that concrete formulas have gotten much more stronger by the late 2000s than concrete formulas pre 2000. This, combined with cheaper and more versatile concrete pumping assemblies mean that constructing beams and structures of bridges with concrete gives a much stronger, yet economically viable bridge, comparing to fabricating the parts out of steel. Thus, modern day bridges are mostly concrete bridges, unless the gap between pillars is too long to get a concrete beam in between.
4. Even the gap between the pillars cannot be arbitrarily fixed, and needs to take into account the local boat traffic or geography, depending on the place. This reduces the options of bridge designs in many places.
5. Lastly, the age of the bridge also plays a key factor. As a bridge ages and more traffic passes over it, the vibration due to the shifting of weight induces micro cracks into the bridge structure (both in steel and concrete). These cracks, even after repairs, do weaken the bridge to the point that after a couple of hundred years or so, the entire bridge needs to be rebuilt. Also, repairing these micro stress cracks is very difficult because they are not only on the surface, but they also are within the structure, which cannot be repaired, unless the entire structure is rebuilt.
I think these 5 major points would summarize the trends in bridge speeds and new plans of construction for railway bridges. Of course the ballast would play a role in reducing the vibrations, but it is only a part of the puzzle.

Sir ap bahut achha samjhate hain
Helo sir.. One question...DMU and EMU dono trains jb station se nikalti hai tb trains ki pickup and speed baaki trains se jada kese hoti h & DMU and EMU dono trains jb station p stop hoti hai tb ek dm se kese ruk jaati h... Is question pr ek video bnao sir pls

Amit sir agar steel wale bridges par train slow chalti h but bogibeel bridge par train full speed se chalti h aur wo bridge pure steel h toh batao fir us par train ki speed full kyu
Mere yha bijnor me balawali railway station ke paas ganga nadhi pr pure 1km ka gitti brijz bna h train full speed me nikalti h
Hiiii amit ji mein rajesh kumar Bihar se hun mein janana hai gurgaon,delhi passenger train kyun nahi chal rahi hai aur station par coolie kyun nahin hai
Thanks for the information
Bhai jab bhi train ko kisi steel structure bridge par rok diya jata hai to wo bridge tutate kyun nahi hai aur woh kitne time tak uska weight utha sakte hain. Please batadijiye. Big fan bhai.

Dear sir Mau junction ke bare me ek video banaiye please 🙏🙏
Sir maina suna hai ki mumbai local traina 16/10/2020 se chalagi kaya yeah such hai kya sir zera ispe ek video banaya sir
Sir I have a question
Hamare jo normal icf coaches hote hai unke boogies aandar alternator fitted hote hai jo coaches ki speed ko reduce kr dete hai upto 100kmph
Par icf raajdhani aur garib rath me same icf bogies use hote hai par unke aandar koi alternators nehi hote because unko power generator car se mil jati hai to isse unki bogies ki speed 130 kmph ki hoti hai(without alternators)
Rahi baat lhb hybrid coaches ki, unkk paas bhi icf bogies hote hai par modified aur alternators ke saath to they can run in speed of 130 kmph.
So aagar ham un modified icf bogies me se alternators nikal de to kya wo 160 kmph me run kar payange? Plz reply
Sir, why are metro Bridge made of concrete only??
Good question
Because they are ballestless track , which consists of less joints or negligible joints on tracks unless there is a cross over, which makes the tracks and train more stable that's why metro use these type of tracks . These ballestless tracks also used in Japanese and Chinese high speed elevated corridor .
Thanks Amit ji ......
Amit Bhai Please make a video on how different locomotives are started
Sir plz tell me 🤔 loco pilot ko duty parr kese bulayajataa hai plz 😍
Hello uncle aap Ludhiana Se banda station Ke aab tak direct train Kyu nehi chale gye hai
Loco pilot ko kaise पता chalega ki bridge m balast hain ya bina blaste isper ek video bnayie... Sir🙏🙏🙏🙏🙏
Amit bhaiya agr electric engine ke dono pantograph OHE se touch krde to kya engine 2 guna force lgyega ya engine nhi chlega
Iske uper ek video bnao

Bhai traction motor to wahi rahegi na.. Double thode honge... Power utna hi rahega...
Zigzag bridges me bhi to full speed me nikalthe hai Jaise u can c at Bally bridge in Kolkata ..dakkhineswar ke bad aata hai towards Dankuni... Trains Cuming from SEALDAH or Kolkata stations only ... Going via Dankuni after Dum Dum JN
Bhai please make a video on kalka mail accident Kaise hua tha
Lekin amitbhai kuch steel bridge par train full speed me bhi jati hai. Aur mene ye experience kiya hai.
Covid trains me kisi specific date ko tkt book krne par amount jayda dikhaa rha hai jbki date specify nhi krne par rate kam hai..aisa kyu?? For eg agar mai 5 oct date select krke availability dekhu to amount jyada hai jbki bina 5 select kiue current date me dekhe to kam... Plz reply

@Knowledge knorr Amit bhaiya apne jo jalebi type ka bole the usko clamp bole the lekin ye clamp nahi hai clamp to vo hote hain jisko tight karke lever se point ko nomar ya reverse kiya jata hai kyu bhaiya hum sahi hain na ?
Amit sir railway station par khane ki chije or Pani ki botal kyu mehangi bechte hai
Aapki baat correct hai ki train ki raftar steel bridge per kam kar di jati hai lekin kuch bridge aise bhi hai jo steel se bane h lekin waha per train ki speed achi hoti hai jaise ki jwalapur haridwar railway station ka bridge
धन्यवाद अमित सर
Sir hamare idr bhi steel bridge 325m ka hai phir bhi train 50 to 60 ki speed mein nikalti hai ?
1)Jab bhi koi train chalti hai to tabi bogie aisi aavaj aati hai maano ki koi metal heel raha ho ya kisi cheez see takrata ho.
2) Rajasthan jaise rajya me railway ne OHE wire jyada uchai par lagaye hai jisse double stack container maalgaadi aaram se jaa sakti hai to Kya railway utni uchai ke double decker passenger train banake Chala sakti hai Kya?
Coach tracks par turn kaise karti hai
Koelwar brigde pr bhi train slow ho jata h good information
Super video 👌👌 sir
Sir prayagraj chheoki n prayagraj jn k beech me naini bridge aata hai jisme balets Ka use nai hua hai fir v train APNI full speed me bridge ko skip Karti hai jabki bridge fully steel structure se manufacturer hua hai

Sir 3.55 per Jo bridge hai
Main usse related आपसे एक सवाल बार बार पूछ रहा हूं
लेकिन आपका अभी तक कोई रिप्लाई नहीं आया
सर मेरा सवाल ये था रेलवे में कुछ पुल लोहे के क्यों बनाए जाते हैं
लोहे से मतलब जो साइड में और उपर छत नुमा एंगल लगाए जाते हैं उनसे है
जबकि 90% पुल बिना लोहे के बने हुए हैं सिर्फ १०% ही लोहे के होंगे
तो ऐसा क्यों कौन से पुल लोहे के बनेंगे और कौन से बिना लोहे के ये कैसे डिसाइड किया जाता है 🙏🙏🙏
Sir I watch all your video, you are the great
Sir Railway Tatkal booking kis basis par hoti hai ? Aur 1 min ke andar hi itni saari seats book kese ho jaati hain ? Aur hume tatkal ticket book krne ka kabhi mauka nhi mil pata hai...plz video banayi iske bare me
Bhai Loco pilot ko kaise patha chalta hai aage bridge hai karel ke... ? Pls is pe yek video banav...
Interesting.Now i will see bridge everytime during traveling
Agar steel bridge ki doori 50m ya 100m tak ho to kya train ki speed kam hogi....???
Very true discription about the topic. Great going Amit ji.......
Sir , Steal wale bridge ke uper steel se dono or dhere jate hai , Concrete wale bridge ko dono or steel se kyun nhi dhere jate hai ??.
Jaisa aapne is video me bataya us se ye sawal aata hai ki Loco pilot ko kaise pata chalta hai ki aage concreet bridge hai ya steel bridge?
Sir may Apna company ka bater bottle railway may ky say sell kar sakta hu plz 🙏 reply kon sa licence lay ga or may ky say sell kar sakta hy
Kon sa licences la gy ga plz reply🙏
Sir I have a doubt
Bridge dekhkr driver train ki speed slow kar dete hai toh unhe kaise pata chalta hoga ki train ne pura brudge cross kiya hai aur abhi speed wapas badha sakte hai ?
Kya guard unhe btata hai ya kuch aur wajah hai .
मे पूछना चाहता हूँ कि locopilot के job कि जानकारी दीजिये
Super knowlege.👍👍👍
