During the early part of 2000 , because of the replacement of track switches at the World Trade Center station , the '' ' E ' '' was extended to Euclid Avenue at all times except late nights , when it operated to Canal Street . Service on the '' ' E ' '' was again affected by the September 11 attacks in 2001 , as its terminal station , World Trade Center , was located at the northeastern corner of the World Trade Center site , so for a time , the '' ' E ' '' again operated to Euclid Avenue in Brooklyn as the local on the IND Fulton Street Line at all times except late nights , replacing the temporarily suspended '' '' '' service . On September 24 , 2001 , '' '' '' service was restored , and '' ' E ' '' service was cut back to Canal Street , since World Trade Center would be closed until January 28 , 2002
