Yes, but in those days, the train took all day.
By 1968, the 13 daily Vanguards had gone done to 7 plus 5 Tridents, so capacity was already reducing significantly.
Interesting also that in those days GLA/LHR had about a third more flights than EDI/LHR, whereas nowadays there's little difference in capacity.
