   * The potential lack of freedom with DCC. There will be a procedure prescribed for most things that you want to do.
   * The potential extra cost of DCC hardware, software and support.
+  * A desire to use a switching method for DC control such as RLSC or Super Bloc.
 ===== DCC =====
 Digital Command Control. DCC systems allow you to simulate prototypical train operation on your model railroad. With DCC you can operate multiple locomotives independently at the same time on the same section of track without a computer and without blocking or other complex wiring schemes. DCC systems use digital data packets to communicate commands to decoders that control locomotives and turnouts on the railroad.     \\ What will it do for me and my railroad?     \\ Simply put, DCC will let you "run your trains, not your track." DCC gives you the freedom to bring your railroad to life! With DCC you have truly prototypical operation at your fingertips.     \\ Why use a digital system rather than an analogue system?     \\ Because digital technology gives extremely reliable operation and the technology is almost infinitely extendible without causing backward compatibility problems (analogue systems are inherently more restrictive). Also, digital systems make wiring simple and easy to install. Because a digital system encodes information sent from the command station to the decoder as numbers grouped into packets, new types of packets can be added to a digital system to send more information thus extending the existing system without causing backward compatibility problems.

 If the feed wires from the power supply unit (PSU) to the load are of sufficient length to have a bit of impedance and supply several loads, then the electrical noise (dirt) caused by one load can cross to other loads. This would usually be positive & negative sharp spikes superimposed on the DC. If the power lines that feed clean and dirty loads exhibit noise, then the effects can also cause  microprocessor  “brown-outs” or resets which may force a re-boot or even more subtle disturbances to your previously happy data.
-The separation of the digital low current circuitry with a separate “clean” PSU is one of the classic precautions to be observed ( as you and we all are frequently reminded on the MERG forum! ). While this may be the best method to provide clean power, it is a good design practice to provide bypass capacitors next to your digital ICs to help diminish the effect of power line noise.
