Question

In two or three sentences describe the connection between the development of steel and the development of railroads

Answer 1

Railroads on the Railways required tracks for the trains to run on them these tracks earlier made up of iron for its heavy duty but soon enough realise that iron was not a very good option for tracks. Meaning drawbacks of using iron for example rusting is it was realised that Steel was a better option in making railroads.  

Steel being made out of iron is heavy duty material yet it is not much prone to rusting. Just addition of certain minerals and carbon in iron steel forging is done making it heavy duty material.
