Can you answer these little known Tube facts?

Gentle quiz for Monday, mostly inspired by someone who inspired a post last week (can't give the person's name away yet, otherwise it would make the quiz much easier).

1. How many stations have the colour of their line in their name and what are they?
2. What's the eastern most station London Underground station that's entirely below ground?
3. What's unique about Upminster Bridge Station?
4. What's unique about Tottenham Hale Tube Station?
5. How many Tube stations have the word London in their name & what are they?

This is just for fun and there's no prizes for guessing the most correctly. Leave your answers in the comments below and try not to look at the answers before you when you comment.  Also try not to look at the Tube map either. 

I'll reveal the answers sometime this weekend.
