Definition of "timetabled"

Freight trains have timetabled paths in the same way as passenger trains, but it is not very often, except in the case of express freight, that they adhere to them.

1961 March, Warren Smith, “The problems of train regulation - a study of operation at Trent”, in Trains Illustrated, page 169

[…] Due to the safety issues identified, ORR has revoked WCRCL's Exemption Certificate. […] WCR-operated charter trains are unaffected by the revocation, which RAIL understands nominally runs until November, immediately after the 'Jacobite' season is due to end on October 27. The 'Jacobite' is treated separately because it is a timetabled service rather than a charter.
