The raildriver will control a steam engine in dcc mode using the forward & reverce handle.But it won't work in cab mode not at this time.
Another thing with raildriver you can put your key board away while driving trains.
There is so much that the raildriver can do such as external view,internal view,chase view,map,bell,horn lever,sandbutton,panagrambutton,E-stopbutton(i use to change junctions forward changes junction in front of train backward to change junction behine train)you can choose the first 7 drivers by the 7 buttons at the bottom.set a button to uncouple the loco from train,and much more.It has a MPH read out for most engines.
I Love my raildriver.(nock on wood no problems in 8 years i had it and use it everyday.
