For anyone who would like to ride the Watford North curve on a normal
service train, TfL has an Easter present for you.

Most of the Met will be closed for track work over the four day
weekend, but TfL says a "special Metropolitan line train service
operates between Northwood and Chesham/Amersham via Watford".

There will be replacement bus services covering the closed parts of
the line not covered by other LU lines.
