Automatic Braking Control (ABC) allows for precision stopping at selected locations such as in front of red signals or in front of points set against the train.

These simple Block Management modules are used with an isolated section of track, to tell the train to stop at a specific location.

For example, when the locomotive decoder receives the “stop” signal status information, the train will stop, if the signal is "green", the train will continue unimpeded.

This can also be used smoothly and accurately stop trains in stations; When used with a toggle type on/off switch. (available in the switches department) Stopping can be controlled from the control area. Go one step further, and use an accessory controller for full DCC override!

The operating details are as follows: if the signal is "red", the BM1 module creates an asymmetrical DCC signal in the braking section. This requires a GOLD or SILVER series decoder (or other ABC compatible decoder). The result is a gentle braking of the train over the pre-set braking distance, until it comes to a halt; the with the either decoder controlled braking delay or decoder controlled braking distance.

If you do not require the train to stop, but to continue unimpeded or to start moving again after the stopping time has elapsed, the BM1 is simply be bridged with a switch. (as shown in the diagram)
