When I started to Thiruvallikeni temple today morning and reached Velacherry, there were two buses waiting there (45A and 21L). Both would go to Triplicane. The former would get you near the temple and the latter would drop you at the Beach and you have to walk for five minutes. I got this very interesting comparison on the buses. There is nothing very deep thought embedded. It is just intended as a humouros comparison.
- 45A by virtue of being routed through all important arterial places in the city like Alwarpet, Royappettah etc with more traffic lights and intersections would take more time. Also it is a common bus (indicated by White Board) which means it would stop in all bus stops. Hence as the name implies, it would take 45 minutes to reach Triplicane.
21L by virtue of taking the route through Chennai Beach road (Adyar, Santhome) takes lesser time. So 21L takes less time like 21 minutes. :)
