QUOTE: Originally posted by fredonia I am thinking about buying an engine and it said that is was analog controlled? SO does that mean that it is DCC or DC?

QUOTE: Originally posted by ebriley if this ol' man remembers right (and that is debateable;o))those old analog systems (Dynatrol, On Board, CTC-80, etc. used to be referred to as CARRIER control rather than COMMAND control. Only since the digital stuff became the standard have we begun to refer to the old stuff as COMMAND control. I've been using CTC-16, etc. from the very beginning (1978ish long before most people had any idea a computer could be smaller than a house, let alone know what digital meant) and they have always been generally called command control. See Model Railroader December 1979 issue. The only time I remember using the word "carrier" was used was when the discussion got technical and we had to distinguish distinguish between the command signal and the power signal. 16 locomotives on the track at the same time without blocks... It was amazing to some people. Of course CVP still produces RAIL COMMAND which is, I believe, CTC-80 on steroids; I have that system too, and by the way, all the throttles, bus and decoders are digital. It doesn't have to be DCC to be digital.

Yes, we have a difference in opinion, but that is what makes a good forum.

Only if there is a device on the receiving end that executes logic based upon the input of that voltage. If the receiving device is a motor, then the DC voltage is not a signal, because the motor has no logic. Voltage does not "signal" a motor to turn, it forces it to turn. If I make a "pushing" gesture to you to indicate you should move back, that's a signal. If I use the same motion of my arm to push you back, that's a force. The difference is that in one case, you're interpreting my movement and acting upon it; in the other my action is physically moving you. What's really cool is that a voltage can be signal and force at the same time if it's connected in parallel to a motor and to a logic device. To the motor it's a force; to the logic device it's a signal. At the end of it all, we'll keep using the name "Analog" for DC train control, because that's the most widespread term. Well, this was fun.

It actually conveys a signal to turn on and off various sound effects. --Randy Modeling the Reading Railroad in the 1950's Visit my web site at www.readingeastpenn.com for construction updates, DCC Info, and more.
