I stay in Marathahalli, near Bangalore and there is a railway line just in front of my house. The railway line connects Bangalore to Chennai and the only traffic in the line is shuttle service between Bangalore and Chennai. Note that there are more than one train between these cities.
Now, I cannot go anywhere without crossing the railway line. And in the past two years of my stay here, I've observed that I am stopped by a train coming from Chennai most of the time [while I wait to cross].
Is this just a coincidence? If not, why?
