Power supply questions and more!

[Anonymous]

I was going to make myself a new layout for my HO trains. I have plans for a couple of industries to have railyards, with switchers on both of them. Naturally, I have some questions.

How would I control them? I sort of was thinking I could "Isolate" the sidings, and have the switcher mover the cars where a main locomotive would pick it up, but that would seem too silly of railroad use.

Another question: For years, I have been using the little Bachmann transformers/controllers for my railroading, mainly because I had a small, simple oval. Now that I'm upgrading to a full-out layout (I have limited space. I'm expecting it will be under 4x8) should I "Gang up" the transformers (I have 4 of 'em, plus a Model Power one of '80's vintage) or invest in a big, nice controller for my layout. (I am seriously considering the latter) What should I look for? what do you recommend?

I must be behind the times(Even though I'm 16![:D]) : What is DCC? Is that where you romotely control the locomotives?

I am interested in upgrading to Kaydees (Despite swearing by horn-hooks for the last couple of years) I am interested in using them for their uncoupling-magnetically ability. Would a electromagnet work there?

Thanks for any suggestions!

If the Bachamn controllers work for you, there is no need to replace them. Having one large power pack means all your trains start and stop together. To control trains separately, you need a throttle (power pack - some power packs have two throttles, most have one) for each one and you need to electrically isolate the track into blocks that you can switch between the packs using toggle switches or rotary switches. A book on wiring model railroads will help you with pictures.

DCC is a system for controling trains by sending a signal on the track that has an address. Each locomotive has a decoder with an address. The decoder responds only to signals with its address. The signal tells it what to do - increase or decrease speed, reverse, etc. The track is not isolated electrically and has a constant voltage. The decoder units control the motor in each unit. Sound and lights can be controlled through the decoder as well. The DCC throttle unit can be switched from one address to another, so one it can control all your trains - just not at the same time (you could have multiple throttle units). This is more expensive than a power pack and each loco requires a decoder (although some systems can have one unit not deocder equiped) .

For Kadee couplers you can use permenant magnets (which are cheaper) or electromagnets. The electromagnet is usually used only on mainlines where there is worry of uncoupling when you don't want it. Kadees uncouple only when there is slack in the couplers, which can some times occur when the train is running and the voltage dips or you slow the train.

The higher the volt amp (VA) rating of a pack, the more current it can deliver. www.modelrec.com
click on the pack picture,, then click on tech 4.

Generally older locos like the P2K older E7s, PAs draw more current, .5 amps. Newer models,Atlas Masters.25 amps so the draw is equally important in determining your requirements.

Your pack must be able to deliver sufficient current to all locos you want to run.

I'm not DCC but one of the biggest players is www.tonystrains.com He has a solid reputation.

Some of those Bachmann packs can be utilizied to power up your accessories such as switches, lighted buildings.
