Whilst it would be nice to have it as a diversion, it’s not practical. Nobody has 57’s on their cards anymore. The voyagers are going and there’s not enough 805’s.
Even if there still some 57s available, the number of trains which could realistically be diverted via the S&C, compared to the normal service, would be a tiny fraction, and the question is what would all those locos do when not required for diversions, ie 99% of the time? Not to mention the difficulty, or actually impossibility, of maintaining route knowledge for a sufficient number of traincrew.
