Today we're going to learn the correct names for the different parts of a London bus stop.
Basics first.
The upright is a post, not a pole.
The bit that sticks out is the flag.
The letter in a red circle at the top is the point letter.
Timetables are enclosed in a Timetable Frame (TTF).
Frames are available in single, double or triple sizes.
More than one frame makes a Timetable Cluster.
The post is made from lightweight aluminium.
The aggregate base is slanted to provide a tactile indicator for the partially sighted and to deflect pushchairs.
The bus stop flag is made up of several constituent parts.
The roundel has a red Bus Stop stripe underneath.
Below that (on a sticker) is the location name.
Below that is the towards information.
Below that are tiles showing individual bus routes.
Officially, only the top part is the flag.
The flag comprises the roundel and location name only.
The boat is separate, and attaches to the bottom of the flag.
The boat combines the towards information, route numbers and sometimes a red tile with additional information.
The Aquatics Centre boat is two rows deep.
The Waterloo Bridge boat is six rows deep.
The Hounslow High Street boat is five rows deep.
Boats are made up of Q-tiles and e-tiles.
e-tiles cover a single tile space. Q-tiles cover three tile spaces.
Q-tiles spread across the entire boat.
The Bow Church boat has only one Q-tile.
The Hounslow High Street boat has two Q-tiles.
Boats are assembled from three sizes of component: 3s, 6s and 9s.
A 3 has one row, and fits 3 e-tiles.
A 6 has two rows, and fits 6 e-tiles.
A 9 has three rows, and fits 9 e-tiles.
There isn't a 12, so the Bow Church boat is a 6 with another 6 underneath.
The Aquatics Centre boat is a 6.
The Waterloo Bridge boat is a 9 with another 9 underneath.
The Hounslow High Street boat is a 6 with a 9 underneath.
The bus stop identification number is hidden on the underside of the boat.
At Wandle Road, the bus stop identification number is 17569.
An SMS plate is attached to the post below the boat and above the TTF.
Simple.
So long as I've interpreted the FoI request properly.
