I would move to London just because of this feature! Seriously! Around 3-4 years ago, I wrote on my old blog about this feature (I later copied that content here, so here’s a link, it’s in Croatian though 
To je planet Internet). I can’t say how thrilled I am to see this feature brought to life. It’s absolutely great!
So basically you open a web site and you see when is the next train due. Is that awesome or what?! I can’t wait to visit London again!

You can do wonders with this, and I hope they will. This was done in only in few hours thanks to TFL API and Google maps.
