Dcc?

[eagle37]

Before I go off buying trains--I have to ask
a *really* basic question. Posters on several
Forums and websites bat around the term DCC as
if everyone knows what that is; however, it has
been over thirty years since I was last into
model railroading: so, in simple terms please,
what is DCC.

Digital Command Control... There is actually a thread on here about it :p

Basically it allows you to control multiple locomotives individually on a single track/circuit... If you use a standard controller, all of the locos would go the same speed, all whistle at once, etc... Where as if you are using a DCC system, one loco can be going full speed, another half speed, etc... It really improves a layout when it is used...

You can read this Wiki article which goes into some of the technical stuff...

That is basically what it is, it lets you "inform" each engine specifically...
