Grade Separator

 

Grade Separator

  • A Grade Separator is a structure that separates the levels of two intersecting transport routes.

  • In Railways and Roads, this includes:

    • Road Over Bridge (ROB) → Road goes above the railway track.

    • Road Under Bridge (RUB) → Road passes under the railway track.

    • Rail Flyover / Rail Over Rail Bridge → When one railway line passes above another.

  • Purpose: To ensure uninterrupted movement, improve safety, and allow higher speed operations.



  • Indian Railways achieved a milestone by conducting a 130 kmph trial run on one of Asia’s longest Grade Separator (Rail Flyover) at Katni, Madhya Pradesh.

  • This bridge demonstrates India’s engineering capabilities and supports modern high-speed railway infrastructure.

  • Grade separators help in decongesting busy junctions, especially where multiple railway lines cross.

  • They reduce accidents at level crossings, improve punctuality, and enhance track capacity utilization.

  • Katni is a vital junction linking routes to Delhi, Mumbai, Kolkata, and Chennai; the new flyover will make operations smoother and faster.


  • भारतीय रेलवे ने कटनी (मध्यप्रदेश) में एशिया के सबसे लंबे ग्रेड सेपरेटर (रेल फ्लाईओवर) पर 130 किमी प्रति घंटे की गति से सफल ट्रायल रन किया।

  • यह पुल भारत की इंजीनियरिंग क्षमता और आधुनिक रेलवे अवसंरचना का प्रमाण है।

  • ग्रेड सेपरेटर में –

    • रोड ओवर ब्रिज (ROB) – सड़क रेलवे लाइन के ऊपर से जाती है।

    • रोड अंडर ब्रिज (RUB) – सड़क रेलवे लाइन के नीचे से जाती है।

    • रेल फ्लाईओवर – एक रेलवे लाइन दूसरी के ऊपर से गुजरती है।

  • इनका मुख्य उद्देश्य है – सुरक्षा, समयबद्धता और ट्रेनों की तेज़ आवाजाही सुनिश्चित करना।

  • कटनी जंक्शन देश का प्रमुख रेल केंद्र है। नया ग्रेड सेपरेटर दिल्ली, मुंबई, कोलकाता और चेन्नई से जुड़ी लाइनों को अधिक सुगम और तेज़ बनाएगा।
