D Train, also known as James D-Train Williams, is an American funk/disco duo from the early 1980s. The group, consisting of James Williams and instrumentalist Hubert Eaves III, is renowned for synthesizing R&B, funk, and early electronic music into a distinctive, dance-friendly style. They are best known for their hit "You're the One For Me," which topped the Billboard Dance chart in 1981 and significantly influenced the post-disco genre. D Train's fusion of electronic elements with traditional soul music set a precedent for future dance music production.
