Russian Armored Trains

As it is well known, the idea to create the first armed trains
appeared in the middle of the XIX century. But the first practical
steps were made only during the Anglo-Boar War, when British
troops had to protect their railroads, which served as main
transport and supply routes, from Boar diversions. First, these
trains were just common locomotives towing flat cars with field
guns placed on them. The Next step was made while increasing
the survivability and firepower of the armed trains, hence common
passenger or coal cars got covered with iron plates with openings
made for small arms and coupled with armored locomotive (usually
protected with sand bags or chains). Such trains are usually called
blinded trains (to differentiate them from typical special-built
armored trains). Finally, typical car armoring styles were developed,
as well as armored locomotives.
