Like most railways,
the RSR today employs exclusively colour-light signals. This was, of
course, not always the case.
Semaphore
Signals
In 1925 the RSR
embarked on a signalling standardisation programme. This called for the
use of identical arms on all semaphore signals and identical aspects
for junctions, calling-on and shunting. All signals were to be
upper-quadrant with an angle of movement of sixty degrees. Splitting
signals for junctions
in the English style had previously not been widespread on the RSR. The
RK
favoured these much more and they were also applied by the RSR in the
1925
project. A special aspect for a diverging route (as used in Germany,
for example) was not considered necessary.

Colour-Light
Signals
The 1925 system persisted until 1964, when a programme of full
colour-light signalling was embarked upon. There had been a few
isolated colour-light installations before that, usually in conjunction
with some other modernisation scheme, notably the stations at
Dämenova Krečki and Dronti and the yards between them in 1937, and
the docks at Bevice Pofedra in 1953. These showed quite clearly the
advantages of colour-light signalling, in particular better visibility
and simpler maintenance. In the 1964 scheme, a diverging route aspect
was provided. The replacement of an entire railway's signalling system
obviously cannot be achieved overnight and it was not until early 1970
that the last semaphores disappeared.
