गर्मी के दिनों में तापमान बढ़ने पर रेल की पटरियों में थोड़ा सा फैलाव आ जाता है इसलिए पटरियों में थोड़ा अंतर रखा जाता है।

Thermal expansion k baje se rails ki size thodi si increase hoti hai. Uske baje se rails me gap rakhte hai

Gaps which r of the order a few mm r provide to allow rooms for the rails to expand the rise in temperature of atmosphere temp as friction causes by running train all material expand when heat and cooled

गर्मी के दिन में रेल की पटरी थोड़ा बढ़ जाती है इसलिए उतना रिक्त स्थान छोड़ा जाता है कि जब बढ़े तब अपने आप को अरजेसट कर लेगा अगर नहीं छोड़ा जाता तों पटरी टेढ़ी हों जाएगी जिससे दुर्घटना हों सकता है

So nice sir

[@amangupta-uy4cx]

Ku ki summer k season me rail ki patriyo me expand hoti h to jgh cover ho jati h

[@suvankarpradhan4417]

In railway track gap is provide becaus metal is expand during rice the temperature and compress decrease the temperature. that's why when temperature is rice in railway track it will be expand and may chance to be crack. To prevent the damage of the railway track that gap is provide
