There's a page or so about it here, and IIRC it was mentioned in

I'm pretty sure it has been discussed in these newsgroups a few times
already.

A generally good article, let down by not understanding the difference
between 2009 and S stock.

I am probably wrong but I thought that Distance to Go signalling on
the Victoria Line was also, in effect, moving block. The article
suggests it is fixed block signalling which I don't think is really
correct.

Oh! That's a more serious limitation then. It implies it uses shorter but
still fixed blocks.
