Whats the reason for the restriction , is it loading gauge or
gradiants or something else entirely?

Height of the tunnels?

ISTR it's carriage length, because of the sharp curve around St Pancras.


If I recall right, there were only certain class 31s allowed to haul the
trains through hotel curve to Kings Cross for a similar reason.
