Wasn't last boxing day the first ever time Washington (And Stanley) had operated their services? I'm pretty sure Depford used to operate all of Washington's service on boxing day. I know for sure the X1 used to be allocated Prince Bishops Solars, then in 2014 it was allocated Fab 57 B9 (as well as 6099 & 6100) so maybe that might be why?
