Colchester or Colchester North is the main railway station for Colchester in Essex, England. It is on the Great Eastern Main Line from London Liverpool Street to Norwich and is a junction for the Sunshine Coast Line to Walton-on-the-Naze and Clacton-on-Sea, which diverges southwards from the main line to the east of the station. The junction is grade-separated so trains passing to and from the Clacton line do not cross the main line.
