Hello all..
No updates recently regarding Breitfurt as I have been busy elsewhere. As this is not layout specific I thought it would be better to star a new topic.
Does anyone have any experience of of the use of route switching using diodes and a capacitor discharge unit? I am a bit confused as how it all works.
When using a CDU in a normal 'one switch per turnout' can one replace the normal passing switches with normal SPST switches. I imagine that this is OK if one has one CDU per turnout but that is not financially viable. But what about with 43 turnouts?
On a related matter, forgetting traction power, where one has switches controlling signals and turnouts, is there any preference as to whether the switch should be on the live or earth side of the unit being operated? The reson I ask is that I want to apply some partial automation using simple logic, probably with relays. In my electronics days the switches (usually semiconductors) always grounded the control lines. However, I am not sure if this is such a good idea when using model rail AC. The is getting quite critical now as I have started wiring the signals.
I hope all that makes sense!
All the best,
Chris.
