Dear Student,
a) Air is highly compressible. As it has pressure it can also handle atm (Atmosphere) pressure. It makes the drving smooth and gives the required friction for driving. Also it is very easily available.
b) Steel is free from rust and it has high tensile strength. It has the resistence to internal and external cracks.

(A):Air is easily available and compressible.Therefore, it is used to inflate tyres.Other gases can also be used but their storage and use will be costly in comparison to air.So, air has a benefit of being cheap
(B):steel is used to make railway lines because steel is very flexible and has the ability to expand it is used because when it expands it does not change it shape, it only becomes bigger making sure it is safe to travel by train.
