 By the 1890s six passenger trains ran each way on a weekday with the majority going from Cambridge or Bury St Edmunds to Marks Tey or Colchester.In 1964 conductor guards collected fares on the trains and all stations on the line became unstaffed apart from Haverhill and Sudbury.Before the line closed (1966–7) there were two trains a day between Sudbury and Cambridge, four between Colchester and Cambridge and six between Marks Tey or Colchester and Sudbury, with a similar number in the reverse direction.
