Love all facets of model railroading and of course the prototype. started with lionel trains at an early age, then discovered command control in the 80's...Keller Engineering and PSI Dynatrol, [remember those systems?]. Then did a stint in Brooklyn N-trak when dcc was first adopted, [Digi-Trax dcc system]. been installing decoders in every scale of loco since then...they fit alot easier in locos than dynatrol receivers ever did.
