I wonder if the simplicity Frances cites, of Soviet engineering, was part of its efficacy in extreme conditions – some regions of Siberia have the greatest annual temperature anywhere in the world, at typically -40 to +40ºC.
Operating steam locomotives in such conditions must have been a challenge to say the least, and their cabs were usually wood-lined to protect the crews. They also had outer hand-rails along the running-plates, ordered by law by the pre-Revolutionary Tsar (Nicholas II?) after a railwayman slipped on the iced steelwork and fell to his death.
Once, my Internet home-page gave a link to a history of a terrible railway project, slave-built under Stalin's rule to link two Siberian coast ports about 700 miles apart. President Kruschev's government quietly abandoned the project, not far from completion. The photographs included a couple of a derelict steam locomotive, stripped of many parts. That is in the High Arctic.

Chokes?
My sister took on our Dad's pride and joy, a Commer motor-caravan with 2.2l petrol-engine. Once day, after she had spent hundreds of ££ restoring it after Dad's long illness had confined it to the garage for many years, she lent it to friends for a day out, in good weather.
They reported it broke down and had to be recovered.
They had either forgotten or ignored her very careful instructions on using the one control totally new and incomprehensible to them – the choke.
