DEMU Full Form In English
DEMU is a type of self-propelled train system used mainly in India for short to medium distance passenger services. In this system, the coaches are powered by a diesel engine which generates electricity, and that electricity runs the traction motors fitted in the bogies. Because the power unit is distributed and not concentrated only in a locomotive, DEMU provides better acceleration and efficiency on suburban and regional routes.
Indian Railways uses DEMU trains widely for non-electrified routes and semi-urban areas. These trains are lightweight, cost-effective, and can start and stop quickly, which makes them ideal for frequent halt services. Many DEMU trains are also fitted with modern passenger facilities, better interiors, and upgraded braking systems.
DEMU is a very important part of the Indian railway network, especially where electric lines are not available. Nowadays, Indian Railways is also modernizing DEMU rakes with better transmission systems and improved fuel efficiency. In some zones, DEMU has been replaced by MEMU on electrified routes.
DEMU Full Form In Hindi
DEMU का पूरा नाम Diesel Electrical Multiple Unit होता है, जिसे हिंदी में डीज़ल इलेक्ट्रिकल मल्टिपल यूनिट कहा जाता है। यह भारतीय रेलवे में एक बहुत महत्वपूर्ण ट्रेन प्रणाली है, जो खास तौर पर उन रूट्स पर चलती है जहां अभी तक इलेक्ट्रिक लाइनें नहीं बिछाई गई हैं। DEMU ट्रेनों में एक अलग लोकोमोटिव इंजन की आवश्यकता नहीं होती, बल्कि हर कोच में पावर डिस्ट्रीब्यूशन होता है। इसमें डीज़ल इंजन बिजली बनाता है और वही बिजली ट्रैक्शन मोटर्स को चलाकर ट्रेन को गति देती है। इस संरचना की वजह से ये ट्रेने तेज़ी से स्पीड पकड़ती हैं और स्टेशन से जल्दी स्टार्ट हो जाती हैं। DEMU ट्रेनों का उपयोग सामान्यतः छोटी और मध्यम दूरी की पैसेंजर सेवाओं में किया जाता है। ये किफायती, हल्की और अधिक एक्सीलरेशन वाली तकनीक है, जो ग्रामीण और उपनगरीय यात्रियों के लिए बहुत सुविधाजनक साबित होती है। इसलिए DEMU रेलवे नेटवर्क का अहम हिस्सा है।
