But the problem is, if we just say XYZ platform, not THE XYZ platform, where XYZ is the name for that platform, just as Charing Cross is the name for a station, which situation makes us say Charing Cross station, not THE Charing Cross station,
Railways started in Britain in the 1840s and for a long time people DID say "the Charing Cross station". Dropping 'the' is a comparatively modern thing. This is a matter of usage and convention, not a grammatical 'rule'. You can still use 'the' if you want to, but it would be considered old fashioned and formal.

I don't actually know where you live, but in all of the countries I have visited, railway station platforms don't have "names". In writing one may choose whether to give a platform a description.
If a station has one platform, either because it is on a single track, or because it has an island platform on a double track, then you could call it 'the platform at XYZ station" without any confusion.
If a station has two platforms, one for each direction, either side of a double track (probably the most common situation in Britain) then the rail companies tend to number them 1 and 2, but many people would describe them by the direction of travel e.g. "the London bound platform at XYZ station" or "the Oxford bound platform at XYZ station".
If a station has more than two platforms, (a busy junction or large city station) then they will be numbered and regular travellers and railway company staff will refer to these e.g "platform 7 at Charing Cross".
However what description a writer chooses to give to a railway station platform will depend on what kind of writing is being done. In e.g. a novel it may not really matter to the reader which platform it is, and the writer may dispense with description: "I met John on the platform at Charing Cross station". If writing instructions, e.g. in a letter or email, about where to meet, one might be more precise e.g. "I'll meet you on platform 10 at King's Cross station".
Bear in mind that in Britain and many other countries you cannot get onto a station platform without first buying a ticket to travel somewhere.
