How does the ABC technology work?
With little effort, ABC manages to accomplish just what model railway enthusiasts crave: precise
on-the-spot stopping in front of signals, slow approach and passage in the opposite direction.
By means of simple modules, which supply the braking section in front of a signal, an asymmetry is
created in the otherwise symmetrical digital track voltage. Naturally, this occurs only if the signal is
at "Stop". This asymmetry informs the locomotive decoder about the signal status: A "Stop" signal
indicates an asymmetry - the train will stop or slow down.
Additional advantages of the ABC technology:
All locomotive functions (e.g. front lighting) can still be switched while the locomotive stops in
front of the signal.
Programming in operational mode (POM) possible.
The locomotive can reverse away again from the signal!
A locomotive can pass in the opposite direction, even if the signal is at "Stop".
Shunting is possible, even if the signal is at "Stop". Simply activate the shunting mode!
No short-circuits when crossing section points between the driving and stopping sections.
