A lot of confusion here, but a kernel of truth. The book Railroad Signaling (2003, pp. 47-49) gives a fairly detailed account of how the color coding of signals evolved over time. It mentions that the use of clear lights did fall out of favor in Britain due to the Abbots Ripton rail accident in early 1876. The signal failure wasn't the only issue, and it was ...

...was Walden Pond ever used for large scale ice harvesting involving rail transport? It seems we can rely on Henry David Thoreau's account to verify this. Thoreau mentions your railroad (emphasis mine): I have thought that Walden Pond would be a good place for business, not solely on account of the railroad and the ice trade; it offers advantages which it ...

There have been trips done in well equipped 4x4s in recent years. You can generally find more info searching in Russian. Several examples: There is a youtube video from 2016 and corresponding news article and blog writeup. A group made it in 2013. An article from 2009. and a youtube channel from the overlanders. For a rough map of the route here is a map (...

It seems the dugout variety canoe mentioned in the question was likely to be the variety encountered still in the mid-19th century. An ethnology titled THE MAYA INDIANS OF SOUTHERN YUCATAN AND NORTHERN BRITISH HONDURAS by Thomas W. F. Gann, published in 1916 has a section concerning boat building: The Indians living in the neighborhood of lakes and rivers ...

Bloemfontein is semi-tropical high plains (1400 metres ASL) with temperatures even in July, its mid winter, not far off what most temperate communities in North America and Western Europe might see in April or September. As shown, freezing temperatures are rare even in the depths of "winter". El Paso Texas is probably the closest U.S. comparable, ...

I agree with the comment of @sempaiscuba Kimberley In 1871 there we no railways to Kimberley. The town of Kimberley was established in 1878. It become part of the Cape Colony in 1880. The railway to Kimberley was only completed in 1885. I assume the planning of the railway started shortly after the diamonds were discovered there in 1871. (Kimberley history) ...

I agree with @T.E.D., this may be a natural sciences question & it may be better suited to SE Earth Science. Many of the tracks look like erosion. This can be the result of a weakness in the rock due to a crack or other discontinuity experiencing water erosion. Other causes could be the breakdown of the geology because of the weight bearing down on ...

By 1850, transportation of convicts had either ended or was about to end in most parts of Australia. The major exception was Western Australia, to where nearly 10,000 convicts were sent on 43 voyages between 1850 and 1868. They were delivered to the Convict Establishment, which would later be known as Freemantle Prison. Some convicts were imprisoned there ...

This is a marxist answer. All answers will be theoretically seated to a question like this, which asks complex questions about theoretically situated categories (purporting to represent real lived experience). Moreover this question has a moral element which requires a theoretical positioning to respond to. The theoretical positioning of marxism is that ...

I'd like to offer another interpretation: the Mayans may not have been using oceangoing canoes at all by the 19th century. Smaller dugouts for inland waterways did continue to exist. Larger vessels are more stable in the ocean, and the historical record of the contact period repeatedly mentions substantial Mayan coasting vessels; see J. Eric S. Thompson for ...
