There was an earlier Trustybus 351 at 1636 on Saturdays - presumably Ye Olde Red Lion was a good pub!
We continue from St Margaret's on the next London-bound AGA train leaving at 1817 and arriving at Tottenham Hale at 1844 Saturday evening.
From your post this bus appears to arrive before it leftWe take the 0058 Brighton and Hove night service N7 to Brighton Marina Village, arriving at 0014 Sunday morning
A night of shuttling about on buses I fear
