What is the reason for such a track laying? It creates a lot of sound when the train passes. Any body knows the reason behind it? It's common in Mumbai suburban area of CR.
I think the main reason for adding this portion to the railway tracks is due to "Expansion of Solids" As we know the when the the temprature changes.... like from summers to winters or vice versa... There can be a probability when tracks tend to expand or contract... So this portion provides a sufficient gap between the tracks so that the tracks dont crack or deform from thier orignal shape.... I think this can be a valid reason.... 😊
Thanks for the reply. Yes this might be a probability. That's once again
This is called Switch Expansion Joint (SEJ) installed at both ends of a Long Welded Rail (LWR). You can search with the terms for knowledge. There is another type of SEJ called 'thick web SEJ' which looks different than the one you clicked ( Thick web SEJ picture attached ; Credits: Asif)
