Latimer Road is the stop -- I know it quite well as I have had regular lessons in Hammersmith that required me to take the tube lines that run through the spot.   I'm fairly certain I know the Grenfell building as the tube is usually  above ground for that stretch of that line and there aren't a lot of tall buildings around.

Latimer Road is not on one of the "key" lines (such as Piccadilly or Central), but closure will cause a number of ordinary people a big headache to get to and from work.    They will probably have to go to Notting Hill Gate.

They had presto card tube passes in London (the Oyster Card) starting about 15 years ago or more.   It's funny -- all the electronic records for the trips taken in 2010 up until end of May have probably just been deleted as it is just 7 years' past now.   I left in April of that year.
