4 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.
