 Momentum is specified in mS / throttle_step.
 
-There is a new command `<m cabid mS>`
+There is a new command `<m cabid accelerating [brake]>`
+where the brake value defaults to the accelerating value.
 
 For example: 
 `<m 3 0>`   sets loco 3 to no momentum.
 `<m 3 21>`   sets loco 3 to 21 mS/step.
+`<m 3 21 42>`   sets loco 3 to 21 mS/step accelerating and 42 mS/step when decelerating.
+
 `<m 0 21>`  sets the default momentum to 21mS/Step for all current and future locos that have not been specifically set.
 `<m 3 -1>`   sets loco 3 to track the default momentum value. 
 
 EXRAIL
-  A new macro `MOMENTUM(mSecPerStep)` sets the momentum value of the current tasks loco. 
+  A new macro `MOMENTUM(accel [, decel])` sets the momentum value of the current tasks loco ot the global default if loco=0. 
 
-Note: Setting Momentum 7,14,21 etc is similar in effect to setting a decoder CV03 to 1,2,3. At present the same momentum value is used for acceleration and deceleration. The `<m>` command may be extended in future to separate these values.
