As upthread, 319433+319457, 433 north 457 south.
I did all 5 trains but not all throughout, doing Euston Watford Euston Bletchley Euston Harrow
Fair number cranks about although I think not as many as last Friday ???
Both 319s noisy, 433 the noisier of the two. 457 no heat (well not in the motor coach anyway); there is another report elsewhere stating 433 no heat, it was certainly heating on all 5 runs I did whereas 457 was not heated and I abandoned it retreating to 433 as therms were as important today as well as decibels.
One other note about 20:54 ex Euston, the last planned diagrammed Euston 319 departure. This train was also the last planned diagrammed public passenger advertised service train departure from London for a DC motored main line EMU.
Pedants can nitpick all they like, but main line excludes LU, departure mean departure not arrival (so next Monday don't count), passenger means passenger not ECS, and London means London, so NT 319, and 507/508, and 318/320 don't count, and 325s ain't passenger.
IMHO that is a sort of significant event. In my ranking of the esoteric anyway.
