Waiting for the train in a cluster

Every day I used to stand at the same point waiting for my train, as it exactly stop at the same position every time, that will help me to make sure when I get off the train, I can walk into exit directly. That is what Steuwt told me, think every little possible to save time when you travel everyday.
That is the reason why people waiting for train in a cluster, as they know there will be a coach entrance.
