It was about 4-6 months ago. I commented on it in another place.
[Rosie] Trains now run from Hammersmith and then effectively transfer from the H&C to the circle. I don't know what proportion do that and whether they can go round a few times and then escape out to Barking. It's been the subject of frantic discussions at CAMREC.

[Software] Spot on. I bought some shoes and paid for Next day delivery, and had them delivered 5 days later. I was furious.

I think they run from Hammersmith to Edgware Road via the circle, then back the other way. I will be down in London (hopefully) later in the week, so I shall report back when I know more. I only realised when I looked at the tube map the other day.

It is all explained here.

[FGZ] It is never worth it. I bought a TV (using my online trade account) to be delivered to my son. I was offered "Next Day" at £12.99 but went for the free option. It was delivered the next day.
