OK. question. I can get (I think) a CDR from Stratford to Hackney Central
and back, correct?

But can I not get a CDR from Stratford to Silvertown and back?

On the same line?

Because I can use Oyster PAYG on the latter, but not on the former.

You can't use Oyster PAYG from Stratford to Silvertown, only to Canning Town

[But you can instead go to London City Airport on the DLR.]
