Q.

In Australia, rail services have been seriously disruptured during the recent heatwave because the railway sleepers have BUCKLED under the heat conditions.

The temperature, at the time, varied from 40-47c.

I understand that such temperatures are not uncommon in India in Summer BUT that railway services are very rarely affected by the heat conditions?

Is this correct and why do railway sleepers not buckle under severe weather conditions in India?

Could it have something to do with the quality of the steel used in the sleepers?

Michael, it is indeed true that in come parts of India temp goes beyong the 40-47 C. As to why the Sleepers do not buckel is a technical question. However now that you have mentiones I have seen Sleepers made out of concrete in some places, may be that is the answer, instead of Steel Concrete better serves in hot conditions.
