Some of the consoles had neon tubes for number display. They emit warm orange lights when triggered by ~300Vdc.

It's not specific to the Soviet world, any control room built before computers looks like that. The examples I'm familiar with is nuclear power plants from the 70s:

- here's Bugey, the oldest active nuclear plant in France: https://cdn-s-www.leprogres.fr/images/5A6732BE-29F9-43FA-806...

- And here's Dampierre, the second oldest, which I was lucky enough to visit: https://www.larep.fr/photoSRC/Gw--/centrale-nucleaire-indust...

I'm sure their's plenty of other control rooms in the same style, for subways, water networks, electricity grid, train networks, scattered around the western world.

As always, big industrial control rooms look amazing. But wow, that way of showing ads is one of the worst I've ever seen. (I really do need adblock on mobile ig)
