It depends which gaps you mean! Older track was laid in discrete sections with gaps left between them to allow for expansion on hot days. There are gaps between rails at the points which are used to connect different tracks together in turn. Is this what you mean?
The size of the gaps between railway sections decreases on a hot day. This is due to thermal expansion. Nowadays different composites are used and different methods employed when laying track so 'continuous' rails may be laid.
They are there to allow for the expansion of the rails during hot weather.
no it doen't because there is little gaps in between and when it gets hot is expands and makes a full. track
two section of railway track are joined together by welding.instead they are laid with gaps between them.fish plates,fastened by nuts and bolts which are able to slide along the oval holes,are used to join two section of railway track......
when the tempreture rises the gaps between the concrete pavement will expand because of the heat.

The tar gaps are where the hwy has been repaired.

You are referring to the gaps between two adjacent rails. Two reasons - 1) depending upon location, gaps are provided under "normal conditions" that will not exist when the rails become very hot (this is because of the rails expanding from heat); 2) gaps are provided which have insulating material inserted to separate rail sections into "blocks" to provide for control of systems such as the wayside signals.
To allow for expansion in hot weather
because of expansion and contraction.
