On older sections of bolted track the gaps were put in to allow for thermal expansion of the rails. On continuous welded rail the gaps are not intentional but the most likely result of removing a defect in the rail.
Gaps in the rails are most likely not intentional but a result of the steel warping or twisting from the weight and inertia of the constant train traffic. In older sections of track the wood ties that support the tracks my be decomposing causing gaps. Many railroads are upgrading to a continuous rail where they use thermite to weld the rails together at the seems, this improves the stability of the tracks and to improve the rail infrastructure.

What would happen if there were no gaps in a bridge?
Expansion and contraction with heat and cold causes the road to swell and shrink. the gaps are for that purpose so the road or bridge would buckle and break if they were not there! Before this was discovered things broke often
How is a bridge protected from a thermal expansion?
Bridges are fixed solidly to the ground at each end and sometimes at intermediate points. The road bed will expand and contract with temperature changes and if there is no provision for this to happen, the road bed can distort or break as the length changes. The same is the case for many elevated structures that have rigid fixings. A common technique to avoid damage is to make a break in the bridge deck. The break has a small gap or flexible insert between the two parts of the bridge deck and as the deck expands and contracts, so the gap changes size. This method means that a minimal force is exerted on the bridge supports and therefore structural damage is avoided. The longer the bridge, the more expansion can take place and several expansion gaps can be used. Typically, the gaps will allow for movement of less than one inch up to as much as twleve inches. Although the principle of expansion joints is very simple, the parts used are precision engineered to allow movement while retaining strength in the deck.
