London tube carriage (illustrious)

Illustrious version of the existing Pony Lora - recreates the interior of a London Underground carriage

Trigger word is "tube_carriage"

Also recognises "across carriage"and "along carriage" to help with orientation, and because without these in the training data it tended to screw up the position of seats relative to aisle.

You can also try adding "tube seats" if you need to show empty seating - plain "seat" tends to give an armchair but in TfL upholstery. Which is nice, but not what we want.
