Unit 21009/10 was on diagram 441 today, bashed it ( my first S stock haulage ) from Harrow on the Hill to Finchley Road on the mid afternoon trip.
Interesting to see that the diagram number appears in all of the carriage side displays, which read: 441 Metropolitan Line ( then destination ).
Internally it was rather chilly, the seating arrangement is interesting but there are rather fore conventional seats ( as opposed to sideways crab seats ) than I had expected. As is usual these days, the interior lights are a zillion watts, but at least they have glare diffusers which cut down some of the discomfort. The ( large ) window to seat match is pretty good.
Question: Should we not have a separate thread for the S stock updates?
