Philly subwayI rode the Philly subway today. In the center of the city, it's all underground. But as it gets in the outskirts, it pops outside and becomes an elevated train. But what I found cool about it is that the driver's cabin only occupies half of the width... so you can actually sit and see in front of the train.
