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

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 🙂♥️

Bht hi acchi Knowledge thi.. Thanks

बहुत अच्छा विडियो हैं भाई ऐसा ही बनाया करो

Very Good Information for Amit Sir. 👌✌

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.

Bahut aachha jankari di aapne

बहुत अच्छी जानकारी दी आपने

Bahut hi jaberjast jankari detay hai

आपके द्वारा दी जाने वाली सभी जानकारियां उपयोगी होती हैं।आपकी वजह से हम लोगों को रेलवे के बारे में बहुत सटीक जानकारियां मिली हैं जो यात्रा के दौरान लाभकारी साबित होती है। इतनी अच्छी जानकारी देने के लिए आपको बहुत बहुत धन्यवाद।

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 👍

Mai bhi abhi tak yahi samajhta tha ki, train kamjor hai isiliye speed slow kar diya jata hai 😊 Thank you Amit.

Very nice information 👍👌

Good information

Sir after12th baad loco pilot kaise ban sakte our kon se book study karni hoti hai plz es par ek video banaeye

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.

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.

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.

Behat Amit ji...... Jab bhi apka channel dekhta hu...... Samajh badh jati h

Very true discription about the topic. Great going Amit ji.......

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

Very nice teaching

Good knowledge. Thanks.

I doubt about your explanation. Check the average speeds of different types of trains, you will find that Premium trains will move faster on the same bridge than passenger trains. Also, if we go by your logic practically each type of train (Passenger to Gatiman) should travel at nearly same speed on each bridge.

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???

THANKS FOR GREAT INFORMATION AMITJI

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

Sir, why are metro Bridge made of concrete only??

@yassarkhan6571

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 .

You are the rail google. Keep it up
