Note that the P trail does NOT go from the usual (Greenford) station for this pub because this part of the Central line isn't running and you will be on a replacement bus from North Action, and NR doesn't run a service to Greenford on Sundays. The trail will be nearly all off road, a change of shoes etc. is advised if it has been raining. Beerintheevening have the wrong postcode for the Black Horse. It is UB6 0AS, not UB6 0AL. Not a problem for anyone following the P trail. Anyone using the Beerintheevening code to come independently will find themselves in an alley at the back of Greenford Tube Station.
