Need some help

Hello everyone, I first thank you for taking time out to read and hopefully
answer my question. I am going to start helping my nephew with a train
layout (this will be HO scale) I have doing some research on how to perform
this. We have bought all types of materials..cork roadbed.. nickel plated
code 100 track...good quality engine and cars...the 4 x 8 piece of plywood,
and the insulating foam. the only thing left to buy before building is the
main transformer power pack...we were looking to get one of the mrc tech
ones. Now this is not going to be an elaborate set up..something for us to
work on together over the weekends...now to my main question..Q) Do I have
to run electrical wire from the transformer power pack to each individual
pieces of track around the payout..or just to the one piece of power
terminal track and solder the pieces all together..just looking for some
advice or input..thanks you very much in advance...

If you are only planning on running one train, one set of leads may suffice. A better idea would be to hook the leads to several different spots around the layout. If you are planning on running more than one train at a time you will need to set up isolated power blocks that can be switched from one control (power pack) to another. There are many books available on the subject.

Steve,
Are you using 'sectional' or 'flex' trackage? If you solder the entire railroad together, you might run into expansion issues. I use flex and have soldered the curves together, and most of the electical blocks. I do have some normal rail joiners yet, but there is a seperate feeder for each section of non-soldered track in a block This is on a 25 by 20 layout. If you are using sectional trackage on a 4 by 8, I would make sure you use 'new' rail joiners(they get 'loose' from all of that 'test' fitting. Then attach your power to the 'terminal' track. With new 'tight' rail joiners, there should be no electrical voltage loss on a small layout. If you still want to solder, you might want to solder the junction of the straight/curved trackage as this is where derailments happen many times. As far as 'rail expansion' goes, I had problems on an old 8 by 13 ft layout with some curves 'popping' the first summer. The current layout has much longer runs, and one would expect that the problem might be worse. When I layed the track, I used a #11 Xacto blade as a spacer between the rails at each joint. This was to allow 'expansion'. Worked fine, but about 2 years later, I started to run in to voltage drop issues, and wound up soldering rail joiners or adding feeders to each piece of flex track(the 'drop' was in a long tunnel - figures).

On a 4'x8' layout, a single set of leads should be sufficient, and you probably don't need to solder, either. Just make sure that the rail joiners are tight fitting.
