Standing underneath the Chicago "L" (short for "elevated") Rapid Transit System serving the city of Chicago. Illinois, USA.
The first "L", the Chicago and South Side Rapid Transit Railroad, began revenue service on June 6, 1892, when a steam locomotive pulling four wooden coaches, carrying more than a couple of dozen people, departed the 39th Street station and arrived at the Congress Street Terminal 14 minutes later, over tracks that are still in use by the Green Line.
Озеро Гижгит находится в Баксанском ущелье Кабардино-Балкарии, недалеко от поселка Былым. Взглянув на озеро, сложно представить, что подобная красота является рукотворной, и к сожалению, даже таит в себе угрозу.
Строго говоря, озеро Гижгит совсем не озеро, а запруда одноименной реки. Дело в том, что в 1940-2000 годы примерно в 10 км от этого места рядом с г. Тырныауз действовал Тырныаузский горно-обогатительный комбинат (ТГОК), специализирующийся на добыче и обогащении вольфрамо-молибденовых руд. В 1966 году в русле реки Гижгит, которая является притоком бурной горной реки Баксан, для нужд ТГОК было построено третье (основное) хвостохранилище, или, если говорить проще, отстойник токсичных отходов производства. Устье реки было перегорожено плотиной, в результате чего в русле горной реки образовалось водохранилище, называемое сейчас озером. Сток воды из озера Гижгит осуществляется по специальному отводному тоннелю в реку Баксан.
Хвосты — профессиональный термин, обозначающий отходы производства руды, зачастую токсичные. Хвостами называют токсичные отходы обогащения полезных ископаемых, соответственно хвостохранилище – комплекс специальных сооружений, предназначенный для их хранения и захоронения.
В годы работы комбината в хвостохранилище по десятикилометровому трубопроводу поступали отходы обогащения вольфрамового, молибденового и медно-висмутового концентратов. Около 30 наименований химических соединений металлов, каждый из которых в сильных концентрациях смертельно опасен для здоровья человека и животных. По различным оценкам, с 1966 по 2001 год тут было захоронено от 25 до 118 млн кубических метров отходов.
В настоящее время трубопровод демонтирован, но отходы остаются в озере. Уровень воды в нем поддерживается при помощи сбросного колодца для водопонижения и водоотведения, связанного с водоотводным каналом, соединяющим озеро с Баксаном. Считается, что отходы на дне озера слиплись практически до состояния цемента.
В 2018 году на страницах научно-технического журнала "Вестник МГСУ" группой ученых (К.А. Гегиев, А.Х. Шерхов, З.Ж. Гергокова и К.К. Анахаев) была опубликована статья под названием "Экологические проблемы Тырныаузского хвостохранилища на реке Гижгит", в которой подробно описана опасность, исходящая от бывшего хранилища ядовитых отходов:
"В обогащенных отходах содержатся до 30 наименований химических соединений металлов (в т.ч. высокого класса опасности), которые с поверхности пляжа хвостохранилища в виде пылеватых облаков переносятся постоянно дующими вдоль долины р. Баксан ветрами (Тырны-Ауз в переводе с балкарского языка «ущелье ветров») на прилегающие к ним сельхозугодья и природные пастбища..."
Гижгит — река в России, протекает в Эльбрусском районе Кабардино-Балкарской Республики. Длина реки составляет 28 км. В низовьях запружена, образует водохранилище-хвостохранилище Тырнаузского горно-обогатительного комбината. В самом низовье протекает по искусственному тоннелю до места впадения в реку Баксан. Устье реки находится в 112 км по левому берегу реки Баксан.
Eight bronze statues, each twice life size, were installed on Vauxhall Bridge in 1907. A year after the bridge was completed. They represent Agriculture, Architecture, Engineering (seen here), Pottery, Education, Fine Arts, Science, and Local Government.
They were designed by F.W. Pomeroy and Alfred Drury and are mounted on the bridge's piers. Each weighs about two tons.
This detail of the little engine, "Wee Georgie Wood", shows how beautifully cared for it is. Precision engineering at its best, the full flowering of the industrial revolution.
It's not hard to find places of historic significance in downtown Launceston. It is Australia's third oldest city after all. But behind this modern shopfront lies a very famous local firm. No we are not in Glasgow, but the engineering firm that is based in these buildings was founded in 1892 by Scottish immigrants James Scott and John Clark.
Glasgow Engineering - 125 Years
This is Engineering on a Small Scale..........it was by my nephew Stephen who is suffering from Parkinson's disease................
This is in the back garden of the house we have lived in for about 40 years, and this is first time I have noticed the manufacturer's name on the manhole cover (unless I've seen it before and forgotten).
One of the most vivid memories I have from my primary school years was visiting the Dover Engineering Works with my school. It's not surprising that seeing molten iron poured from a ladle into a mould from close quarters would make a lasting impression on a child. I can still see clearly in my mind the wooden pattern they had made of our school's badge being pressed into the compacted black sandy material in the mould. The pattern was then removed and the top half of the mould filled with more compacted material was fitted. Small holes to allow the escape of burning gas were made in the material. When the molten iron was poured into the mould, sure enough, jets of flame appeared from these holes. When the mould was eventually stripped, there was the grey/silver replica of the wooden pattern.
When the company was established in 1830 it was on the outskirts of Dover in the parish of Charlton, with a supply of water from the adjacent River Dour. Charlton has since been absorbed by Dover, and the engineering works is of course gone - with the site now occupied by a supermarket.
Department of Engineering, University of Cambridge. Not happy with this one, but will have to do for now as I wanted a general shot of the department building and I did find the staircase interesting!
Some oddly over-engineered stairs and fencing for flats above the Old World Deli on State St. in Bellingham. Guess the builder didn't want to pay for any engineering, so just beefed it up until he said, "That ought to hold anything."
genetic engineering
could create the perfect race
could create an unknown life-force
that could us exterminate
introducing worker clone
as our subordinated slave
his expertise proficiency
will surely dig our grave
it's so tempting
will biologists resist
when he becomes the creator
will he let us exist
bionic man is jumping
through the television set
he's about to materialise
and guess who's coming next

Long Island Rail Road (LIRR) engineering inspection vehicle TC82, manufactured by Plasser, is seen crossing Borden Ave in Long Island City, Queens as it starts an inspection run back out to points east. This is clearly an unusual sight, as even other rail road employees at the adjacent facility are looking on!
The first of five engineering trains booked to pass within an hour, Colas’ 56049 Robin of Templecombe 1938-2013 rolls past Stapleton Road on 15/09/2024 with 6C24 08:30 Little Mill Junction-Westbury Down TC.
In the end, four ran, with the first two passing by before the cloud rolled in.
Yeah i love my green lotus! What i tried to do in this picture was create the sort of picture you would see in a magazine, maybe with some text beside it endorsing lotus's engineering skills. I don't know, but i hope you enjoy!
50019 'Ramillies' in engineers blue livery at Gloucester in October 1989.
This is one of very few photos I took of 'Ramillies' in this livery though I did see it at Worcester on an engineers train [black and white and now in the ownership of Martin Loader]. I seem to recall that this was in the November. Most of my journeys from London were via the north Cotswold line and I can't remember now why I took a different route?!
Onsite Hydraulic Repair, 24/7 UK coverage. Each van is professionally kitted out with the appropriate tools for removal, manufacture and refitting of hydraulic hose assemblies accompanied by stock to ensure that 99% of jos are carried out there and then.
Hope the quality has kept on this shot. Having to upload if off my phone via all sorts of weird methods thanks to some pikey stealing the wires down at the Internet exchange place leaving me with no Internet.
UP 2666 and another Tier 4 ET44AH lead northbound UP Engineering Special PJCPR2 through Villa Grove after a heck of a rainstorm. Luckily, its late departure out of Jefferson City, MO allowed me to get a shot of it after work.
Standing outside this century old barn, I looked up to see an aircraft flying overhead and thought of how far we'd come. The barn featured a unique swing beam construction that allowed a team of horses, hitched to a wagon, to turn around without having to back up. Horses apparently don't like to walk backwards so this made life easier for farmer and animal alike. When you compare that marvel of practical engineering to the complexity of the plane, it seems there are no limits to what we can accomplish.
For the Pessimist, the glass is half empty.
For the Optimist the glass is half full.
For the Engineer, the glass is twice as big as it needs to be.
