On rails?

That blue icon – it indicates the transit option on google maps – is it a train, or a streetcar?

Not that it matters in our neighborhood, because google maps doesn't know about the DC Metro system. Busses, yes; Metrorail, no. Google won't put you on a train.

Look what happens when you ask for directions from the Bethesda to the Grosvenor stations. That's five minutes on the Red Line – but google puts you on a bus for more than half an hour:

Maybe they should use an icon of a bus, if that's what they mean.

[Not that we mind busses; we rode the 31 & the 33 today.]
