It's a good idea to have a DC controller to test locos before fitting decoders. They are also useful for powering accessories such as point motors or lights.
Don't be tempted to test a DC loco using the 00 setting of a DCC controller.

Don't you have Listed Buildings status like we have in the UK? Any building here that has listed building status, because it is considered to have historical importance, can not be demolished.

You are correct Roger. It's a shame really as it would be nice to have direct contact with a representative of the firm.

They do, and I did. In the first reply. 
HuskySteve never came back so we don't know if he got his problem sorted.

Is your 08 like this? http://www.mrol.com.au/Articles/DCC/BachmannClass08.aspx

Peco track is made in the small town of Beer, Devon in the south of England.

No need to have a short time delay. All you have to do is put insulated rail joiners on the frog rails, which I would recommend for DC layouts too. The example was given to illustrate the short circuit protection. There is no problem with DCC track being powered at all times. It's designed for it.
Marklin also have a DCC system which I understand has been around for 27 years, longer than NMRA DCC.
What carrier control? DCC doesn't have carrier control.

If there's a short a DCC system will cut the power almost instantly. Far faster than a DC system. An example with dead frog turnouts. If the back to back distance between the wheels is too wide, or the tires on very old locos are very wide. As they run over the frog they may cause a short circuit. On DC systems the loco will usually keep going as the short circuit detection on a DC controller is relatively slow. On a DCC system the short circuit detection is extremely fast and the power will be cut before any damage can occur.

In Germany, Marklin have been using 16v AC for decades, maybe even longer than 12v DC, without safety problems caused by screwdrivers across the tracks shorting the layout.

I have no problems with my DCC locos shorting on turnouts. If the wiring is done properly there should be no shorts. There is no safety problem leaving DCC locos on powered track. It's DC locos that should not be left stationary on DCC track. The lights on a DCC loco can be turned off with a push of a button. There's usually a headlight symbol on the controller.
Where do you get the $66.00 for frame milling and converter Albert? The highest price I could find for a replacement frame was $15.00 with most being $10.00 plus $22.00 for a suitable decoder. Or you could mill the frames yourself as I did when I wanted to put LED lights in a DC loco.

While it's possible to run one DC loco on a DCC system, by a process called zero stretching, it is not recommended as it can burn out the motor, especially when the loco is stationary.
See Mark Gurries page about running DC locos on DCC and a full explanation of zero stretching.

No, I did not mean on the same train. I meant moving from one oval to the other with seperate trains.
No, there is no danger of fire because the controller cuts the power when there's a short.
No, you do not need to isolate sections to 'park' a loco.
No, DCC is not sensitive to voltage drop,  interruptions or dirty track with modern stay alive decoders. They will even cope with dirty track far better than DC locos.
No, uncoupling on the fly is not unprototypical. It used to happen all the time with passenger trains at speed.

You call opening roofs on cargo trucks a gimmick. Others might call it adding to operational interest.
How do you operate these blocks when using a helper engine? Why complicate the wiring with blocks and switches when you don't have to?
How is the hobby going to survive if you keep visiting youngsters away from your layout?
Programming locos is no more difficult than dialing a phone number.
I don't read the modelling press, so I'm not affected by any advertising.
DCC locos need no converting to run on DC power.
Do the lights on real locos dim when they slow down?

I'm not trying to change the minds of confirmed DCers. I know from experience that it's impossible.

DCC is 21 years old this year. Quite a long time for a gimmick. The wiring is simpler. Take a couple of oval sections of track joined by turnouts with two locomotives. Using DC, swap the locos from one oval to the other without using isolated sections. Can you do it? I know I can with DCC.  "Thus you have additional potential (no pun intended) for short circuits and fires." A short circuit is a short circuit whether you're using DC or DCC. A DCC controller will cut out a lot faster than a DC controller, so reducing any presumed chance of fires.

DCC can do a lot of things not possible with DC. You can have uncoupling anywhere on the layout. You can attach helper engines at the back of your trian if there is a steep incline. You can have cargo trucks with opening roofs where you can lift the cargo out with a crane. If you have youngsters visiting who like to run trains at 300mph full throttle you can restrict the maximum speed. There are many more things possible too and more are in development.

Have you ever heard a sound fitted N scale loco Doneldon? The sound quality in my Big Boy is great.
The sound quality depends on the quality of the decoder, the speaker, it's enclosure and the sound files. You can't really judge by watching Youtube videos. Mine sounds far better in RL than on video.
Here's the Z scale sound loco I was talking about showing what can be done even in the smallest scales.

It's very practical. I have two with sound decoders. You can even get Z scale with sound decoders.
