London Bridge canopy detail
Parts of the canopies are linked by metal grids over the trains. They
look like they were put up to support a glass roof but the roof was cancelled. Does anyone know what's going on? And why are they only a few carriages long? |

And why are they only a few carriages long? People tend not to walk too far from the entrance even with a full length canopy IME. Full length trains (TL being probably the main exception) don't run all day but when they do there will tend to be less time to wait while at other times the trains will be shorter. Finally - it costs less money not to go all the way with canopies. |

Having looked at how the canopies' columns on the platforms were flapping around in the breeze during construction in some of the time lapse films, they look like the current function is horizontal bracing so that in effect there is one overall roof (with holes) across several tracks. They might also come in handy for hanging some proper electrification off at some time in the future. ;-) |
