The NR item seems to show a 323 at Rugeley Town.
Presumably that means some live tests have been done over the line.
Is it really true that 323s have begun LNWR Birmingham-Liverpool runs (I know they used to for Central in the 1990s)? Quite a downgrade if so.
I'd have thought 323s in Liverpool would be Northern's units coming via the L&M (or maybe on training runs from Liverpool to/from Crewe).
And finally, I thought the EMUs for the Chase line were included in the 350/3-4 deal, also involving a string of WMT cascades on other electric routes?
The TPE 350/4s are still to transfer, of course, after the 397s are in service.
