Another way of lifting miners in/out of the mine was to use a "man lift" This consisted of a number of small steps fixed to the vertical pump rod of a beam engine. The steam engine was on the surface, and drove the pump at the shaft bottom by a shaft.
To travel to the surface, the miner climbed up a few meters by a stairway. and then when the pump shaft was near the bottom of its stroke, they stepped of the landing and onto the nearest step on the pump rod. When the rod was near the top of its travel, they stepped of it and onto a landing. Wait briefly, and then when the shaft is again near the bottom of its travel, step on it. Repeat as needed until the surface is reached.
Each stroke of the engine took about one minute, and could lift a man by most of the vertical stroke. Worked well until there was a terrible accident when the pump rod broke, taking many lives.
A somewhat similar device was used to move persons and light packages from one floor to another in a large factory or works, known as a "vertical conveyor belt"

A proper intercity train has a minimum of 8 coaches, gangwayed throughout, with first at one end, and a full sized buffet car between first and standard.
It has space for cycles, surfboards,luggage etc.
A 5 car DMU▸ is not a proper inter-city train. The 5+5 and 9 car DMUs are almost as bad.

A similar principle to the Paternoster lift. |

William Huskisson MP▸ was the first person to be killed by a train while crossing the tracks, in 1830. Many more have died in the same way since then. Don't take a chance: stop, look, listen.
"Level crossings are safe, unless they are used in an unsafe manner." Discuss.

A similar principle to the Paternoster lift. Yes, it is in my view regrettable that Paternoster lifts are now virtually extinct in the UK▸ . Sheffield university has one, said to be the largest in the world, and Imperial College, London had one that was reputedly taken out of use after a fatal accident, and AFAIK▸ a hospital still has one but for staff use only, not open to the public. A variety of foolish pranks may be played including going over the top, and then performing a handstand so as to confirm the urban myth that going over the top inverts one. https://www.bbc.co.uk/news/av/uk-england-south-yorkshire-42997131Great fun  |

We should have one at Bristol Temple Meads, to access platform 14.  |

I'd forgotten the length of a fathom. Reminded of it by the discovery that the name comes from an old word meaning 'Outstretched arms'.
Mark
Peoples arms have on average got longer, and finger tip to finger tip is now nearer 2 metres than 2 yards, in many cases. |

Now this is remarkably topical, as I have just this moment been able to ask my daughter to measure my own horizontally outstretched arms, finger-tip to finger-tip, even while she is cooking a late-night snack. She gave the answer as 182 centimetres - which I promptly converted to 72 inches, in old money. Therefore, I am the traditional fathom wide. Chris. |

It lifts food from the kitchen in the basement. It's new - it would have been installed in the past year or so when the branch was opened. The floor of each lift platform is like a comb, which passes through a fixed facing comb at servery level, and the food item gently slides from the platform to a holding area, from which staff assemble the the customer's order. I was impressed at how this makes excellent use of space in the confined site. |
