What Power Will I Need?

I'd go with a Lionel KW.  Plenty of power in case you add more accessories, several fixed voltages and variable voltages for fine-tuning accessory operation- you might find that those 022 switches work better on a little more than 14V.

Larry,

Since the switches only require power to operate momentarily their only other draw is for the lanterns.  The smallest of transformers should provide adequate power for them.

 

Power consumption for other purposes really depends on the accessory. Obviously, features such as multiple lights, operating motors and smoke units will draw more than a simple street light.  While there are probably stats on each accessory, it's likely you'll need to play it by ear to see how many you can connect to any one transformer at a time.  I'd be inclined to connect lighting to one variable output...that's the simple part.  Operating accessories generally need fine tuning individually with the voltage but with experimentation can be paired together on variable voltage or fixed voltage taps.  Probably best to mount and wire temporarily until you hit upon the right combo.  Older Lionel transformers should be ideal for the purpose.

Any basic transformer will do as far as powering the accessories and all. Obviously, one might consider the power draw when operating even a modest sized layout because of the power needed to operate the locomotive(s).

I don't think the Z750 has aux power outputs, but the Z1000 does have fixed 14v aux power outputs. The Z1000 should have plenty of power to do what you want.

 

However, I have never used any of the switches you have so I have no idea if you will need higher than the 14 volts put out by the aux outputs to operate them properly? 

rtr12, 14 volts is the minimum test voltage specified in the LIONEL service manual for testing PW 022 switches.  The manual specifies testing at 14-16 volts.  Personally, I would be reluctant to build a layout using minimum specs--Murphy's law.

 

Of course, I don't know the cost difference or availability difference, if any, among the transformers Larry is considering. 

With overhead, figuring 3 watts per bulb, you will need about 90 watts of output from your transformer before you even throw a switch. Having 15 illuminated switches with controllers is heading towards a good size layout, and you will need some power on the level of a SW, LW, or KW for switch & accessory power.

Watch out for too much overvoltage on the accessory bus.  Adding just 10% to the voltage will cut incandescent bulb life to 1/3 of normal.

Thanks for all the  replies fellas.  I am going to start with a Z1000 and test the 022 switches and see how 14V accessory power works. If not high enough I will use the controller and main power and adjust till everything works. I may just use  8 of the 0-22 and get some K lines also. They already have LEDS in the switches.  May go to LED Bulbs in the o-22s and switch controllers. I just don't know enough yet.   I'll keep you all posted as I get started.  Thanks
