Of course, the actual order was confirmed in, I think, 2013, not 2008,
when discussions first started. So there's really no good reason why the
spec wasn't updated to include Wi-Fi in the intervening five years of
debate, discussion and negotiation.

Is there any plan to fit them with wifi post-delivery?

Allegedly.

Out of interest, does anyone know how the uplink in train wifi is done in the
UK? Does it use the cellular network or is it a proprietary radio system?

It's a mixture of satellite and HSDPA mobile. Coverage can be very
patchy outside of urban areas. The main problem with the Elizabeth Line
will be whether there's any mobile coverage in the tunnels. Existing HEx
tunnels do have GSM coverage.
