I fail to see how this is relevant.  I would assume that the amount of
friction is already modeled in the acceleration constants; if it were
zero then the brakes would be nonfunctional and the train would not be
able to accelerate or decelerate at all.  In any case, a change in
friction simply works out to a change in acceleration.  The equations
above still hold true.
