In the 1904 Tour, many riders took the train but just because that happened back in the day doesn't mean it should be accepted today.
Old videos can include even up to the last five or ten years - It's an issue of whether this should ever be considered by the judiciary - Many times particularly in stage races a GC contender and a non-GC contender work together and the Non-GC contender is gifted the stage - Who knows what arrangement is made on the road - For example in this year's Tour of Yorkshire Lawless gifted the stage to Van Avermaat.
