Braintree Train

This week I have very consistently been catching the 7:34 bus from Arlington to Davis Square, where I hop on the subway to get to Kendall/MIT. Yesterday and today I had the same train conductor, and I know this because this man has a special talent. First, I must tell you that the red line train has two ultimate destinations, a train can either be heading to Braintree station or to Ashmont Station. It's typically written on the train and the conductor will also usually announce it. I've noticed conductors at rush hour usually don't bother announcing much about the destinations and that's reserved for off-rush hour traffic that is more likely to contain tourists. However, this conductor, I want to call him something, so let's call him George, he announces destinations in a big way. In fact at each stop he announced that the destination of this train is Braintree on average 30 times at EACH stop. So as we pull into the station it sounds something like this:

"The destination of this train is Braintree Station, this is a Braintree Train-braintree train-braintree-braintree-braintree-braintree-braintree-braintree-Brain tree train-braintree-braintree-braintree-braintree-Braintree trainbraintree-braintree-(BIG BREATH IN) braintree Trainbraintree-braintree-braintree-braintree-braintree-braintree-braintree-Braintree train"

Yesterday, when I heard it at the first stop I thought it was kind of amusing. Then by the fourth stop, my stop, I was a little aggravated. When it happened today, I decided to count the number of times I heard braintree:
Porter: 24
Harvard: 29
Central: 39
MIT: 28

Counting helped keep me from losing my mind. Monday, I plan on taking a stopwatch to see if I can correlate the number of times with the amount of time the door is open. There's a few possibilities that I and my officemates can come up with:
1) George has a bit of an obsessive-compulsive disorder
2) George got chastised for not announcing the destination of the train at some point in time
3) That train is missing the sign that announces the destination
4) George is bored with his job and has to entertain himself somehow

I figure I can support hypothesis #1 if I can find a pattern and correlation with the stop or day of the week. Let's just hope that my own OCD behavior will not have me riding on this train between Braintree and Alewife all day with George in order to get a whole lot of information.
