People tend to check in during these times:
Get off here for Park Royal station. Short walk.
More there are few rubbish bins at this station.
If you use the hotels here then make sure you leave by the right exit to find the one your using.
Don't get off, you won't like it, it's vile.
Public toilets at this station, unusual and not super pleasant, but worth knowing. They are in the entrance hall
If going the West Ruislip sit near the front so you get off near the stairs
Get on the last carriage if you go to shepherds bush or euston
The ticket office is only open until 10:15am on weekdays so if you have an issue that needs human help don't expect to get it at this station after 10:15!
If you're arriving from Central London, take the last carriage for the exit! Or the first carriage from West Ruislip!
Walk to the far end of the platform (back of train) for a seat into London during rush hour
