The tunnels are simply too hot, and cooling them down is inordinately difficult. The Perfect Storm of Thermal Chaos The Tube’s heat problem isn’t just about one thing gone wrong – it’s about everything gone wrong at once. When Victorian engineers designed these tunnels, cooling wasn’t...

The train passes Lake Thun and ascends into the Alps, passing through the Lötschberg and then Simplon tunnels. In summer when it's light you'll get some great mountain & lake views across Switzerland and northern Italy. Stay overnight in Milan: Affordable hotels with good reviews outside ...
the worst of all, engineering consultants who actively weaponize “technical design criteria” and “insuperable community opposition” to, say, find a four track elevated station utterly impossible to build, but hey, check out this four-track underground design with two levels of stacked tunnels!
The URTs operate most of the time in tunnels, where the operating environment is relatively stable and less affected by uncertain disturbances. Nevertheless, during the actual operation, it remains susceptible to unpredictable external disturbances caused by variations in environmental factors. Especially ...
The uncompleted tunnels created big bottlenecks, hampering supplies transportation from Anatolia to the Ottoman and German armies stationed in Mesopotamia. Tunneling works were accelerated and in 1917, the 600mm gauge track that was laid for construction purpose finally came through both tunnels. It wa...
it usually looks more realistic to include gentle curves (just like on a real railroad) and position the mainline at a slight angle from the edge of the benchwork. Hiding the curves with tunnels or hill cuts effectively distracts the eye from the fact that the train is running around an ...
