What will happen to steel railroad tracks on a hot day if they were laid out during a cold day without clearance or gap?

When metals become cold, they contract and take less space, but when a metal gets hot, it expands and it will need more space. So, in this case the metal tracks took less space when fitted without gaps on the cold day, but on the hot day the metals will need more space and therefore will push outwards. The tracks will become buckled, and when the train comes, it will go off track.
