For the same reason we refer to ships with personal pronouns: to reflect the animacy of the thing referred to. As for why they're female, it's traditional, same as ships. National personifications have tended to be female (not invariably). If you think this "reflects badly", well OK. You presumably think the Royal Navy's Twitter feed likewise reflects badly on them. I disagree.What rammed tubes? Where?
I decided to get the bus to work today as, while two weeks ago the tube numbers were down, last week they were down so much that I started wondering about my safety. I avoided getting into a carriage that just had one man in it, and saw the only other person on the platform, a woman, do the same. (We looked at each other and knew.)
Why are you referring to countries using female pronouns? It doesn't reflect well on you.
Regarding the far more pressing issue of the Tube, it'll vary by time, place and line. Some cars are empty. There's been footage of other trains rammed. Unless the definition of "essential" work is restricted, or more trains put on (or both), the risk remains.
