Clever: ABC technology

Just give it a try!

ABC is simple. And safe. And really easy. You can try it yourself. Since installation can be done later and easily reversed, you can test ABC on your layout or on a separate track. You’ll love ABC!

Simple guides:

Really easy-to-understand guides on how ABC technology works and its applications are available in three articles published in MIBA EXTRA Modellbahn digital. With the author’s and publisher’s kind permission, we’ve made these articles available here as PDFs:

ABC: Braking, Block Sections, Shuttle Traffic with Digital plus

With Digital plus ABC technology (Automatic Braking Control), combined with all current Digital plus locomotive decoders (as well as older Digital plus decoders supporting ABC, such as the GOLD and SILVER series), hardware-based train control becomes possible. ABC thus achieves what model railway enthusiasts want with minimal effort: precise stopping in front of signals and passage in the opposite direction. ABC currently offers three braking modules:

BM1 implements stopping in front of a signal
BM2 adds a slow-speed function alongside stopping
BM3 enables automatic block sections

These modules influence track sections before the signal, allowing the decoder in the locomotive to receive information about the signal state depending on the direction of travel.

How does ABC work?

ABC modules create an asymmetry on the track, recognized by ABC-compatible decoders and interpreted based on the individual settings in the CVs, for example:

slow down and stop
move slowly
slow down, stop, and after a defined waiting period, start moving in the opposite direction (shuttle operation)

The driving information on the track (speed, direction) is not altered by ABC, which is also why locomotives with decoders not supporting ABC simply continue to run normally and unchanged.

What else can ABC do?

While in a section supplied with asymmetric digital voltage, the locomotive remains fully controllable:

Functions can be activated
Programming on the Main (PoM) is possible
The locomotive can reverse away from the signal
Shunting is possible even with a closed signal
No short circuits occur when crossing the gaps.

Requirements

To use BM1, BM2, and BM3 block section modules, locomotive decoders from the STANDARD+ V2, SILVER+, or GOLD+ series, or others that also support the ABC method, as well as suitable amplifiers/central units (LZV100, LZV200, LV101, LV102), are required.
