Railway tracks have gaps to allow for expansion when the tracks heat up. As the tracks get hotter, they expand and get slightly larger. Without the gaps, the tracks would buckle from the force of the expansion. They have fishplates located between the joins to force the rails back into lateral alignment and thus prevent derailments.
In modern continuously welded rail these gaps are often cut on a diagonal to prevent this misalignment. The thermal expansion and contraction of rail track is minimal and the forces push to the outside rather than along the rail.
They are also there because segments of rail have traditionally been required to be removed and replaced easily and so had to be made a manageable length.
Heat expands metal, to prevent buckling in the rails the tracks are in pieces with gaps. Another reason is in case of lighting strike the electric current can only travel as far as the first gap, this preventing electrical charge getting to a train car or electrical box.
because the railway lines expand during the summer and by the friction of the train with it . if the gap is not kept the rail lines would expand and break. so to avoid the breaking of the rails the gap is kept
There is gaps between railways because during summer when the sun will heat the rail which is made of iron will obviously expand.
After some calculation an approximate distance is left between them.
After this answer you will ask but what in winter and how does the train pass on the gaps?
So this gap is nothing for the train. It is left so that during expansion when the railways will expand the rail will not change direction.
For e.g:-
imagine when you take 2 drinking pipe and joint them together it will change direction or even damage.
when heat is supplied to a substance or material it will expand.during summer the tracks get heated as a result it will expand. if gaps are not provided, that may result in the bending of tracks.
Railway tracks have expansion joints to prevent them from warping when they expand during very hot weather. The metal on railway tracks can conduct a lot of heat during sunny periods.
There are small gaps between the length of the railway track because when the temperature is hot the metal will expand and cause the train to crash. So if there is a gap between the length of the train tracks the metal wont join together and cause the train to crash. When the weather is hot have you ever noticed that the trains go slower? Thats just in case the metal joins together.
A.thermal conductivity
B.specific heat
C.thermal expansion
D.thermal insulation
The gaps are there to allow for the expansion (lengthening) of the rails in hot weather. Without any gaps, the rails would buckle and go out of alignment.
I am assuming you are talking about the spaces between the ends of the segments of the track. If there were no gaps when the tracks got warmed up (usually by the sun) then they would buckle as they expand causing the train to potentially derail.
The gaps between the rails were originally there because rail was carried and installed by hand. Remember this was in a time when welding on site was either not possible or later too expensive.
Later when continuous welded rail became possible, it was found that every so often you need to allow space for the rail to expand and contract due to temperature changes.
in the scientific view. by heat objects will enlarge.that is the reason
As we all know that on heating a substance makes it expand. So when the trains run on the railway tracks they produce heat and the tracks get expanded.

Which metal is used to mend railway tracks?
The key element in railway lines depending on the railway line is, occasionally copper, magnesium and stainless steel.
Why do railway lines have gaps in them?
to allow for the thermal expansion or contraction
What are the effects of expansion and contraction in the design of bridges pavements and MRT lines?
- MRT and Railway tracksif a continuous track of metal is used, it will expand in hot weather and bent. trains running on bent tracks may be derailed. to prevent this, railway tracks are laid in sections with expansion gaps between them. A sliding joint between adjoining rails allows them to expand without bending.- bridgesboth concrete and steel bridges are built with allowance for expansion and contraction due to changes in the surrounding temperatures. Rollers and sliding joints allow for the movements of the bridges as it expands and contracts
How do railway engineers make sure that railway tracks are parallel?
In Great Britian, when track is being laided, there is a track machine used to "tamper" the track so they are straight and parallel to each other.
What is a interlocking plant in railway signalling?
In railway signalling, an interlocking is an arrangement of signal apparatus that prevents conflicting movements through an arrangement of tracks such as junctions or crossings.he signalling appliances and tracks are sometimes collectively referred to as an interlocking plant.An interlocking is designed so that it is impossible to give clear signals to trains unless the route to be used is proved to be safe.
What are the disadvantage of railway tracks if no put gaps?
If there is no gap between two successive railway tracks, the friction in it by train wheels increases its temperature and is expanded. Due to this, the tracks may get deformed when they force each other sideways.and due to thermal expansion also
What is the function of the gaps at the railway?
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?
Why must there be gaps in railways?
There are gaps in railroad tracks to ensure that the tracks will not buckle in extremely hot weather
Why are there spaces along railroad tracks?
When you look at a stretch of railway track, you will notice spaces in between the metal tracks. The reason for this is that metal will expand when it grows warmer, and will shrink when it grows colder. These gaps allow for the metal to expand, so that when it is an extremely hot day, the railway tracks won't bend all out of shape causing trains to derail.
Why does the size of the gaps of a railway track expand on a hot day?
The metal rails of a railway track expand when heated by the sun on a hot day. This expansion causes the gaps between the rail segments to also increase in size. To prevent accidents, railway tracks are designed to have gaps that can allow for this expansion without causing any issues.
Are railway tracks and railway lines the same?
No. Railway tracks are only the rails and ties/sleepers and hardware used to hold the track in place. A railway line is a set of tracks designed to move a train between at least 2 points. A railway line can consist of many tracks.
What country has more railway tracks France or belgium?
France has more railway tracks than Belgium.
Are railway tracks parallel?
Yes
Why are there gaps in railway lines?
because of expansion and contraction.
Why do railway tracks sound louder in winter than in summer is it expansion or contraction?
Contraction is the reason that railway tracks sound louder in winter.
What is the total length of railway tracks in France?
France has 29,901 kilometres of railway.
Why do engineers build bridges and railway lines with gaps in between?
Because differences in temperature cause the materials to either shrink or expand. With a lot of shrinking and expanding occurring, these materials would crack or break down if there wasn't any allowance for the movement. Also these gaps are used to compensate for the weight of the load crossing vehicles which presses the bridge to its maximum shear capacity. The gaps serve as this allowance for movement in terms of both temperature and weight. Many railway tracks no longer make use of these gaps as they are pre-tensioned and then placed into position in this "stretched" form. Thus, as temperature rises, the tension in the tracks decreases, but the material does not buckle, since it is already stretched!!!
