I am back!

I remember there was a few requests about more control rooms when I started posting here last time, so I thought I might honor the request even if it doesn't show much of the room part...

Anyway, this is the fully automated control panel for the rail yard at Uppsala Centralstation in Uppsala, this photo was taken on 1938/05/11 and published in the local paper, Uppsala Nya Tidning, the day after.

This machine controls the switches and signals of the rail yard at the station, a similar model can be found operational and in use at the local heritage railroad.

Sadly I don't know what the indicators mean, or how to operate it, I just think it is cool!

This photo was taken by Paul Sandberg, and is in the public domain.

In fact, in Japan, they have what they call "point and tell". Essentially, every signal drivers see, they point at it and say what it tells them, for instance, "proceed at max 50 km/h". It does quite a bit to increase safety, because it forces you to consciously acknowledge safety relevant points.
