I have been informed by a very senior person of this website that only the use of the franchise name of West Midland Trains is acceptable on threads, rather than the use of their two branded service names.
That is not actually what I said.
The rules (post #1) require you to state "
the company who's service you are using" and that
has not changed.
At the time of writing NRE does give the company name (though I believe that may change in future) which is
West Midlands Trains, though you are right to point out that there is confusion over this matter (I intend to create a dedicated thread on the matter, but there are plenty of existing threads where this has cropped up recently).
I have not actually stated that "only the franchise name" is to be used; if anyone wishes to write
both the company name and the brand name, I do not think that is against any rule. Whether it's worth typing both out, given how long winded that would be, is another matter!
(And yes the rules should be stating
whose rather than
who's, before anyone spots that!

)
