Explanation:
The thermite reaction is a redox reaction that is very important in metallurgy. The reaction is as follows;
2 Al(s) + Fe2O3(s) --> 2Fe (s) + Al2O3 (s).
In this reaction, aluminium is oxidized from 0 to +3 oxidation state while iron is reduced from +3 to zero oxidation state from left to right respectively as shown in the reaction equation above.
This reaction occurs at high temperature and as a result of this, it can be used to join metals at such high temperature. This is why the reaction can be used to join rail tracks.
