I'd guess it's over 40c inside that building. It's a great render, the only thing I find jarring is the power transformer, but to be fair, I can't recall seeing a telegraph pole model anywhere. Thanks for sharing.

Don't be too "jarred" my friend.....
1850: About 12,000 miles of line from 20 companies now exist in the United States. This just happens to be one of them although it is no longer in use  
Transformers Were Invented in the 1800s
The fundamental principles behind transformers were first described by Michael Faraday in 1831, with the discovery of electromagnetic induction. However, the practical transformer as we know it today emerged in the 1880s, primarily through the work of engineers like Lucien Gaulard and Sebastian Ferranti.
By the 1890s, transformers had become central to the spread of alternating current (AC) electricity, enabling long-distance transmission and powering the development of the modern electrical grid.
