Modern Railways has reached me. And, I have read the article. It is
very interesting, but why does TfL have to be so non-standard. Can
they not utilize a system compatible with the rest of the UK.

Don't be silly - they can't even utilise a system compatible with their
own ATO lines already in operation! TfL are the dictionary definition of
an organisation that has to constantly reinvent the wheel. And waste god
knows how many hundreds of millions in the process.
