#141
Distance controlled
stopping
(constant stopping dis-
tance)
Setting the distance
0 - 255 0
This CV defines the “constant stopping” distance. The
right value for the existing stop sections has to be de-
termined by trial.
Use these figures as a starting point:
CV #141 = 255 is about 500m (500 yards) for a
real train or 6m (18 ft) in HO.
CV #141=50 about 100 m (100 yards) for a
real train or 1.2m in H0 (4 ft.).
Use the appropriate scale factor for other scales.
#142
High-speed compen-
sation
using the ABC method
0 - 255 12
A delayed recognition (see CV #134), but also unreli-
able electrical contact between rails and wheels, have
a larger effect on a stop point at higher speeds than at
lower speeds. This effect is corrected with CV #142.
= 12: Default. This setting usually works fine if
CV #134 is also set to default.
#143
… compensation us-
ing the HLU method
0 - 255 0
The HLU method is more reliable than the ABC meth-
od; no recognition delay is usually required in CV
#134; this CV can remain at default value 0.
The distance controlled stopping can take place in two possible ways; see diagram below: The
first is the recommended method (CV #140 = 1, 2 ,3), where a train entering at less than full
speed continues at the same speed for some time before it starts braking at a “normal” decel-
eration rate (same rate as would be applied at full speed).
In the second method (CV #140 = 11, 12, 13), the train immediately starts braking when enter-
ing the stop section, even when entering at a lower speed, which may lead to an un-
prototypical behavior. It may however be useful to use this method if used together with de-
coders from other manufacturers that do not have the capability mentioned above, in order to
harmonize the brake sequences.
The second method may also be the preferred method if distance controlled stopping is used
manually (CV #140 = 2 or 12), so that the train reacts immediately to speed changes from the
throttle.

Second method
for a constant
stopping distance
“Distance controlled stopping“, when activated, is
exclusively applied to decelera-
tions leading to a full stop, but not to speed reductions without stopping (these
are still handled by CV #4). Neither is there any influence to acceleration events.
The traveled distance is constantly being recalculated in order to get as close as possible to
the desired stop point. The deceleration rate within distance controlled stopping is always ap-
plied exponentially, that is the deceleration rate is high in the top speed range followed by gen-
tle braking until the train comes to a full stop; which in this case is
not governed by CV #122!
The application of CV #121 for exponential acceleration however remains unchanged.

Shunting, Half-Speed and MAN Functions
On the one hand, defining the different Configuration Variables (#3, 4, 121, 122 and 123) of-
fers prototypical acceleration and deceleration behavior, but is on the other hand often obstruc-
tive for quick and easy shunting.
This is why the momentum can temporarily be reduced or eliminated altogether with a function
key of your choice. Also, during shunting maneuvers it is sometimes helpful to cut the speed
range of the throttle in half.
For historical reasons, the assignments of these "shunting-key functions" are summarized in
CV #124,
which is associated with restrictions and also relatively confusing.
From today’s perspective,
CV's #155, #156 and #157
are the preferred CV’s for these set-
tings, where function keys can be selected in a systematic and unlimited manner for each of
the shunting and MAN functions. However, Bits 0 and 1 in CV #124 still need to be set for the
desired momentum deactivation effect
, even if the relevant keys are defined with CV’s #155 -
157.

Select a function key for
LOW GEAR ACTIVATION:
Bit 4 = 1 (and Bit 3 = 0): F3 as half-speed key
Bit 3 = 1 (and Bit 4 = 0): F7 as half-speed key
Select a function key for
MOMENTUM DEACTIVATION:
Bit 2 = 0 (and Bit 6 = 0): “MN” key for deactivation,
Bit 2 = 1 (and Bit 6 = 0): F4 key for deactivation
Bit 6 = 1 (Bit 2 is irrelevant): F3 for deactivation.
Effect of above key (MN, F3 or F4) on
MOMENTUM:
Bit 1, 0 = 00: no effect on momentum
= 01: removes momentum of
CV #121 + #122
= 10: CV #3 + #4 reduced to ¼.
= 11: removes all momentum above.
EXAMPLES:
F3 for half speed-key: CV #124 = 16.
F3 for half speed-key and F4 to remove momentum
completely: Bits 0, 1, 2 & 4 = 1; that is CV #124 =23.
