Charlie Colin (November 22, 1966 – c. May 17, 2024) was an American musician. He was the bassist for the rock band Train, of which he was a founding member. He also played guitar and provided background vocals for many other bands after his departure from the group in 2003.
Colin attended University of Southern California to explore his artistic gifts; then he transferred halfway to focus primarily on his musical gifts at Berklee College of Music in Boston.[5] Attending Berklee got Colin fully immersed in music. He started playing with seniors for lessons and so he could learn more. Pat Metheny was quite a discovery, as well as other kinds of music discovered during Berklee.[6]
Shortly afterwards, Colin got an offer from some friends to go to Singapore to write and play jingles.[3]

Hotchkiss headed to San Francisco and met Pat Monahan, Train's future lead singer. The two collaborated on songs in the Bay Area and invited Jimmy Stafford to be the guitarist and Colin as the bassist. Colin brought in Scott Underwood to play drums. Thus formed in 1993[9] Train became very successful.[10] Train scored their first Top 20 hit with 1999's "Meet Virginia," although their big breakthrough came with 2001's "Drops of Jupiter", which reached No. 5. The album Drops of Jupiter reached No. 6. on the Billboard 200.[9] The group toured nationally, opening concerts for Hootie & the Blowfish,[11] Sheryl Crow,[3] Counting Crows,[12] and Barenaked Ladies.[13]
