As the temperature outside drops, the activities in the Shed are less obvious to the passers-by. One such area of inconspicuous works is the exhibition of railway telecommunication. Despite the cold outside works are possible thanks to the constant heating provided by two masonry heaters and one temporary furnace, fed with the firewood collected during the summer clean-up of the shed’s surroundings. Therefore, we have enough time to painstakingly reassemble and paint the overhead cable ducts. It is also an opportunity to inspect our collection of Strowger selecting switches, which we plan to use in the future expansion of the exhibition.
