Random London Overground question

[ComingUpTrumps]

I live in London, and any time I go on the Overground or to a Tube station with an Overground connection, I always hear that it's been part-suspended between Gospel Oak and Barking.

I'm weirdly curious about this. Does this mean that you can never go east to Barking on the Overground from Gospel Oak?!

Anyone got a possible answer to this totally inane question?

That part was suspended for months last year because of engineering works.

It's temporary. They're doing works in it.

Ahh thanks :)
