I would like to know if the TEE coaches still required the generatorIf you could read what I wrote you would have had the answer before you asked the question. They got a "convertitore statico da 45 kVA (da 65 kVA sulle ristoranti)" for all international voltages.
Moreover the TEE didn't come with a generator car (as was usual by SNCF and RENFE) but with an inverter car that could produce 660 V three phase current from the standard current available in each country, brought to the coaches by a separate cable.
"L'unico veicolo dipendente dalla macchina era il furgone, che prelava l'energia necessaria tramite la condotta del REC alle quattro tensioni del RIC (3000 V cc, 1500 V cc e ca, 1000 V ca 16 2/3 Hz) che veniva convertita a 660 V ca 50 Hz trifase, mediante un gruppo rotante moto-alternatore da 240 kVA."
Citations from the Principe book.
so, the technical development from 1969 to the 1980ies allowed to replace a central rotating inverter (of 240 kVA) per train with static inverters (of 45 kVA) on each coach.
To compare: The Eurofima coaches of 1977, of which SBB had 20 and FS 100, had a static inverter of 35 kVA (EA 7/77).
