I was told that if you want to visualise a hectare, try to think of something 100m x 100m...
By definition, therefore, a hectare is square, although any shape could constitute a hectare. I can relate that to around the length of a football pitch, squared. An acre, by definition, is long and narrow, so harder to visualise. The M32 from where the traffic from Eastville roundabout meets the inbound carriageway to behind the White Swan? The acre would have been easy to visualise at the time and place of its origins; a certain number (presumably 22) of standard length furrows in the open field system. Absolutely in tune with its application. Less relevant now as a result of enclosures, mechanised agriculture, few of us being farmers, etc. |

Doesn't the railway still use "Chains" to measure distance along the track?
Fortunately a chain is 20 m, unless you're being really picky. Yes it is 20.1168 m which is neither here nor there for finding an asset that is quite big - like a bridge or a set of points. Unless you start adding them up all the way from Paddington, in which case after 100km you could be a way out! I suppose they still use miles and chains because otherwise they would need to need to spend money replacing all the mileposts and asset records that are measured in miles and chains. I don't know how much truth there is in this, but it's been said that they would need to resurvey everything rather than convert. Because the Victorian navvy gangs were paid by the chain, they would claim a chain at say 21 yards rather than 22. Over the length of the railway, it amounted to enough extra pay to be worth it. |

Former cabinet member Mhairi Threlfall... said: “Dear @networkrail why on earth have you opted for these? My bike has very high handle bars so will not fit, I reckon this will be similar for many women let alone the pure weight of my bike means I can never use the top slider, the curved roof is a nonsense. #sexistinfrastructure” Do Raleigh still make Choppers then? I presume that is what Mhairi Threlfall is riding. A retro-Chopper was launched a few years ago to ride the retro wave but somehow I doubt if that's anything like Mhairi Threlfall's bike. She used to have a Bristol Bike but the photo below is from a tweet of hers about it being stolen, so I don't know what she has now.  https://twitter.com/mthrel/status/1184338913386733569 |

If it's like the ones at BPW» then it's not complicated. Takes a bit of strength and height, doesn't move as smoothly as that promo (well, it wouldn't, would it?) but within most adult capabilities. The most annoying aspect is probably the locking possibilities – you can only lock through a wheel, not the frame, which isn't really safe for overnight parking in most urban UK▸ locations. But at least it's not wheel benders...

So it could be anything but I'd presume it to be a dataset loaded to a GPS device, which will bleep or buzz at the appropriate places. Hopefully to alert the driver to a recommended deviation rather than simply "low bridge 100m ahead".
