Incidentally, the first high frequency installation of fluorescent lamps was on the train carraiges of the London Undeground. Formerly that company operated its own independent power station which generated a 400Hz mains frequency. Owing to the fact that the inductance of a ballast varies as a function of its operating frequency , special units had to be engineered for this installation. Due to the very high frequency , you will not see the lights flickering and will not hear a buzzing sound from fluorescent lamps using electronic ballasts.
Magnetic Ballasts In contrast to the multiple induction coils on the electronic type, magnetic ballasts only use one single coil.
