On our trip from Östersund to Vilhelmina I took a few photos of some "centrallås". The first one was at Lit, north of Östersund:

Jämtlands Sikås had a rebuild from parts of an older crank ("vev") frame:

The keys are all present in the frame, even the K14 key for closing the station, but not all of them are turned:

I took the station building only when we left the station, against the sun:

The following picture shows the distant signal of Ulriksfors. The flashing green light means "danger". A white flashing light would mean "proceed"—the colours are similar to the ones used in Central Europe up to the 1920s!

At Ulriksfors, we were supplied with sandwiches!—however, one had to queue up:

Passengers who already had their sandwich were waiting in the sun:

Home signal A is still cleared. The lights for the distant signals seem to indicate whether the signal is in order, as they are alight for both distants. Were they on all the time, or only when a route was locked? In the center of the panel, one can see the controls and indicators for a set of barriers:

A little later, a key had been inserted into the panel—was it to return the signal to stop?

Finally, I took this picture of ground-operated points without blade locks:
