Is that a concrete-enough example?
I don't think the maps are an issue either, but you pretending to be ignorant that they are attacked, and that lines between them are attacked, is weird.
What I'm saying maps of STATIONS have nothing to do with TRAINS being attacked. It seems like you think trains and stations are the same thing, and that's something you'll need to figure out for yourself.
> detonated at Edgware Road
Said it yourself!
It was in a train carriage of a train which had just left Edgware Road station. We use the label "Edgware Road" to identify which of the bombings it was.
I'm genuinely embarrassed for you at this point.
