Well crumbs I don't know! However my statement that the logo is used
only for the National Rail network still holds true - I haven't heard
of any non national-rail stations where it is used only of some NR
stations where for some reason it isn't.

With the exception of St Pancras though, non NR station have an alternative
logo which convers what sort of train you are likely to get from there, and
how it is different to a NR station.

The news that St P doesn't have it is a great shame IMO - but not
surprising. Signage is to St Pancras International what Etch-A-Sketch is to
art.
