Märklin H0 - 3 x licht bloksignaal 74391, 3 x licht voorsignaal 74380, 1 x signaal schakelunit 72750 - Model train (7)

This puzzle consists of 7 components to be organized into 3 sets, namely:
1 set consisting of 3 light block signals controlled digitally with the signal controller. Red to stop the train, green to let it pass.
One set consisting of three light pre-signals that are automatically controlled whenever the block signal changes (the signal switches to red or green).
A signaling switch unit that allows the setting of the block signal light to be changed from red to green. The main signal light then automatically updates accordingly.
A clear manual is included to properly connect the e.e.a. to the rails. All units have been tested and work perfectly. Each unit is individually packed in its original packaging and comes with documentation.
The signals have been used and come from a landscape that I unfortunately had to dismantle.
The signal switching unit is new and has not been used yet; it has only been tested and works excellently. This signal switch is suitable for 4 connections. In this package, there are 3 signals, so you will have one connection left over to connect something else.
