The basic signals (FREEWARE)
This bundle comprises the simple signals, that is the two and three aspect signals. These will be available in the mastmounted version as well as the version to be used suspended from catenary bridges. These signals will have neither LOD nor scripted functions.
The enhanced signals.
What we are working with, in this first batch, is the system L which is the most widespread of the two systems used on the SBB lines. I am working with Andreas Halalko Møller on this and we will use an adapted version of his script for the DSB signals. The System N (Neu/New) will come later, there is enough work involved in completing the old system already. For more info on the different signal systems see Roland Smiderkal's excellent site on the subject.
Why script? Because the
Swiss system involves speed signalling as well as a mere
STOP-PROCEED-CAUTION function. That is why you see up to six lanterns on a
signal, the seventh lantern in the picture being a backup red. Hence you can
see as many as three green lights at the same time on a signal meaning 90
km/h.
But there is more than that. Why must a signal be gridlocked? We see no
reason that a signal must stick to the rails just because it can. A signal
is really nothing more than a scenery item that shows some predefined states
by way of lights. So we pack the "logic" into a trackside object which is
part of the Signum safety system - a so-called crocodile - and link the
signal to it. That way we achieve a lot of benefits; height adjustability
and rotatability being the most significant.
