Please enjoy the Hitachi full SiC-VVVF sound of the TX3000 series, a new train for the Tsukuba Express♪ I thought the VVVF inverter sound sounded familiar, but the acceleration sound is different from the Hitachi "keen" sound of the past, and is a Toyo IGBT "keen" tone from 2:29, and somehow the VVVF sound is familiar even though it is a new train. However, the synchronous mode is a SiC-like sound that can also be heard with Mitsubishi full SiC? Also, the all-electric brake sound is a fade-out type that can be heard a lot in recent Hitachi VVVF from 3:27, and can be heard louder and clearer than hybrid SiC trains. Good sound level: ★★★★☆4 [Good sound♪ Sound train video series] ↓Please enjoy these as well↓ • [Good sound♪] Tsukuba Express VVVF sound collection [Hitachi & Toshiba IGBT] TX1000・TX2000 series VVVF sound collection
