पटरियों के मध्य स्थान, (ठोस के एक सामान्य गुण, गर्म करने पर फैलने और ठंडा करने पर सिकुड़ने से पटरियों को सुरक्षित रखने के लिए रखते हैं।) अगर पटरियों के मध्य स्थान नही देगे तो पटरियां टूटने का खतरा रहता हैं।

Gaps are left in between rails. This is done to provide the room for the rails to expand when the temperature rises. If it is not done the rails would expand and bend on getting heated.

Gap maintain in railway track because when train pass on the track heat developed so temperature increases. Size of track expand due to increase in temperature and gap filluped, neither gap between the track it can bends the track there may be an accident.

Here is the answer related to gap between tracks , it's basically due to the change in temperature in various seasons , which leads to track expands and contracts , and for prevention of the cracks and the damage , gaps are provided are there in railway tracks .

Railways tracks has a gap because in Summer they heat up and tends to expand up to certain limite . If these gap not given then railway tracks are bend due to thermally expansion of track

Gap in railway lines bcz Railway line made from iron , train run on thier lines then its start heat and falling To use falne k liye space ki jarurat hoti h Agar space nii hoga to jb train chalegi or iron garam hoke falegi to railway line mai fault aane ka risk bhaot jda inc. Ho jata h

[@kajalkesar7330]

Solid high temperature pr thoda sa phailta h aur hmara jo railway track h vo solid ka hi ek example h jo ki summer day me thoda sa expand hota hai isiliye gap chhodna necessary h.

Railway tracks induces thermal expansion during heat so gaps are provided
