Power Source/Transformer Input?

Tripleo-

The 80 watt transformer would have no problems powering the layout, but if you plan on running anything more than a basic starter set the Z4000 is the way to go. Typically the larger transformers are priced anywhere from $.80-$1.00 per watt, so $200 for a 400 watt Z4000 in working condition sounds like a good deal.

As an aside, given you desire to have someone push a button to make the trains run on demand, I would recommend running conventionally with the reversing units locked out. I'm not too familiar with the Dallee line, but if you were operating the units in command mode, the Dallee module would have to send out a signal to each locomotive to "go", then "stop" after a fixed period. With conventional operation all you have to do is either add or remove power to the tracks.

I vote with John, go for the Z 4000.  more flexibility for the  future!

Thanks for the input!

My main concern is reliability and ease of operation. The track is going to be approximately 7 feet above the floor running on the edge of a series of retail food coolers and freezers. Should be interesting (I hope). The Dallee system will start and stop the operation with gradual increases and reduction in speed, and they have an option that will always stop the train in the same spot, regardless of the timer having run out. Haven't decided if that option is all that important, though. I am thinking that I will be running conventional stuff only, and probably locked into forward so as to eliminate the possibility of the E unit cycling into neutral or reverse.

Keep in mind that I'm a novice at this stuff - don't have a layout of my own. Just a small double loop with crossover that I run under the Christmas tree every year. I just got this idea to do this layout, and I'm gonna "by golly" get it done, one way or another.

do a test layout at home first. It does not have to be by the ceiling, but you should see how everything works and if it works reliably BEFORE you install it.
