Generally, you can find that the pillars holding the track of metro trains have a broader base.
This is because the broader base is quite stable equilibrium than other types. Hence, the stability is better and often preferred for the construction of metro train tracks.

Answer:
Metro trains run over broad bridge that is supported by pillars having broad base.
As we know that-
Pressure = Force/ Area
Broad bridge on which metro train runs, exerts large amount of force at the base that is the pillars holding the bridge experience this force. Broader base of pillar provides larger surface area, decreasing the pressure exerted on it.
This prevents any kind of damage ( for instance, falling of bridge under the influence of gravity) to the metro track.
