Electro-mechanical lever frame at Albacina, 1990

Deutsche Version dieses Postings

On one of the next days, we made a trip to Macerata via Albacina. Here is the first handful of photos, up to Albacina.

The first two pictures show signals for a level crossings ("segnale di protezione di un PL", where PL means "passaggi a livello", i.e., level passage). Similar to FS's signal book, I show them in reverse order, because the signals were for different crossings. The first signal is a protection signal proper (segnale di protezione) indicating that the barriers are closed and hence the track is free (via libera):

The second one is the corresponding distant signal (segnale di avviso), which tells the driver that the following protection signal will show "via libera" (avviso di via libera):

Rusty tracks contained some old steam locomotives—I think this was at the junction station Fabriano, but I'm not really sure:

At Albacina I was allowed to take photos of the lever frame, an electro-mechanical one like the one at Ciampino::

At the upper right, one can see the line block instrument—it looks brand-new and quite British. Here is an enlargement from the first of the previous images, without any more explanations, as I don't know the details of its workings (a nice picture of a similar instrument is show in the master's theses "Il Segnalamento: Principi e Tecnologie per la Regolazione del Traffico Ferroviario" by Ludovico Zampiero from 2016, which can be found on the internet as a downloadable file):

A work train occupied on of the tracks:

This starting signal (for the track on the right of it) can show digits 1 or 2, depending on whether the train departs on the left line towards Falconara or the right one to Macerata:

A zoom of the signal to the left of it (click on the picture shows it in full scan resolution) surprisingly reveals that also this signal can show both digits—even though it is not possible to traverse to the track to Macerata from there:

Here is the somewhat shabby station building:

And here is a last image of the lever frame. Signal or track relays are placed even above the frame—somehow, it seems that the signal box became too small at some point:
