WHAT would be the POINT in doing that??? Can you really see anyone in their right mind agreeing to such a ridiculous idea? No.... crewing difficulties aside, T-Bird Frank and 19D3326 are spot-on in their observations. If 60163 is not likely to be ready in time, or, indeed, available, there is surely still potential for a second train that day - with another loco at the head (perhaps a red one?) and a "meet" somewhere less likely to cause disruption to other traffic, than that suggested at Carlisle. Just one final thought, given the imminent spate of weekend diversions over the S&C, can anyone be absolutely certain that even 1T57 will be permitted to run on the planned Sunday???
