We interrupt our journey from Watford at North Harrow and walk to West Harrow, as this is a lot faster than turning around at Harrow-On-The-Hill or (much later) Rayner's Lane and then turning around again to carry on in our original direction.
One group of people is expected to stay on the train here and will actually do the turning around at Harrow-On-The-Hill thing, but they plan to carry on and head into town via the Piccadilly Line. It's an interesting approach.
If we walk fairly briskly then we might get to West Harrow in time for the train before the one that I've planned, which will give us a 7 minute leeway we can use up later on.

The 06:21 was 5 minutes late out of Moor Park, which meant we left there 5 mins ahead of schedule, and got asked to be quiet whilst we were on the platform, despite Moor Park being in the middle of nowhere. Unfortunately we lost the extra time as the southbound train left just as we arrived at Watford.
