The fault of MTA upper management that fails to DEMAND that all NTTs be fully compatible

As I noted earlier, if this happens, NYCTA would end up being one of the few agencies world-wide with that demand. We're going to either end up paying through the nose for that custom feature, or we'll get a failed spec with the agency taking a token payment in exchange for not meeting the spec.

there must be ONE standard CBTC system for ALL lines

That's an interesting comment given that Paris RATP has been pushing for interoperability for their CBTC installations. IIRC, multiple contracts have been given to Alstom, Ansaldo, and Siemens* for CBTC units. Per this, NYCTA is trying to do something similar between its existing suppliers, Siemens and Thales.

*The Siemens installation is related to Canarsie Line's CBTC installation...

should br upgradable like most computers

They're not like most computers. They're digital industrial control systems, not off the shelf desktop systems.
