I would like to use my tortise switch machines left from my HO days on my new layout. I know the switch controler can operate them , but I would also like to have push buttons on the layout to run them. is this posable or am i stuck with running them only from the hand held. I know lionel is comming out with a new control for the DZ2500 machines that i have but they are not as reliable as the tortise. lots to think about along with the demise of the TMCC upgrades i have also thought about converting all my stuff to DCC as the sound and programing abilities are great. thanks for your thoughts Rick
