London Overground- first train of the day

[NSE]

Hey all,
Was waiting at West Hampsted and casually looking at the time tables for the NNL, looking out for any anomalies. I then saw that the first and last trains of the day start and end at Willesden Junction, nothing strange here. However they depart/arrive from the lower level and the timetable indicates they still stop at Kensal Rise and on to West Hampstead as usual. I can't see how this would work without a reversal just north of Willesden (at first I thought Primrose Hill line, but then they can't stop at any NLL stations till Camden Road) and I don't fancy getting down to Willesden for 5 am, so if anyone does know how this service works, i'd appreciate them explaining it to me.
Many thanks

There's a junction just south of WJN LL that takes you straight up on to the NLL towards the East.

Take a look here...

There's a short double track spur allowing access from the low-level platform to the NLL to/from the east.

I didn't realise there was a connection south of the platforms. Thanks guys

Thats how the HL trains get back to Euston or the TMD
