Could someone here please help settle a petty argument I'm having with a
friend?

Central Line: I need to get to South Woodford on the Epping branch (So can
take Epping, Debden and Loughton trains) and he needs to get to Redbridge
(so can take any Hainault train).

Of course I think there are more Hainault trains; he reckons the opposite.
Who is right? Apart from spending a day counting trains, is there any way to
prove it either way?

Thanks!
