Wiring fas track to run a conventional train and a blue tooth lion express train.

Bill,

There are others more knowledgeable than me, but I'm going to give it  shot.

• Can I use the included transformer from this 90's train on the fas track by hard wiring it too the contacts on the bottom of the track?  YES, Will this power supply be able to handle two trains? Depends on the wattage of the transformer. My guess is no.
• How does the blue tooth train reduce its power?  It doesn't. All of the LionChief trains use an 18 volt AC walwart power supply. This is a non-variable transformer. Is it from the tender car, the engine, or does the power supply have a built in way to reduce power?Power comes in the engine and is reduce to whatever is needed via the circuit cards inside. The only thing inside the tender is the speaker for the PE.
• Is the fas track always energized at full strength and the remote reduces the power either in the tender, the engine or the power supply and not the track? The PE uses "full power" (voltage). The remote only controls the functions of the engine.
• Would running this conventional train on the fas track affect the motor? No. Is running the train dependent on how the fas track is powered either conventionally or by blue tooth? Running the older engine requires the older transformer. This is how the speed of the engine is controlled. If you use the walwart on the older engine...It will operate at full speed always, no control.
• Is having the switch between the loops complicating things?  If you run two different style of engines, Yes. Should I just isolate the inside loop to run it as a conventional and leave the outside loop to run blue tooth? Yes, if you want to run both engines at the same time. Is there a way to turn one track off and on with some kind of rocker switch to accomplish running two trains on one track? With the two engines you currently have, running both on one track will not work.
• Should I try to figure in a way to run the metal conventional track inside of the larger loop fas track and run both trains on their intended power supply options? You can run fastrack on both loops no problem. They do need to be isolated. You can run the PE on a variable transformer, But it needs to be at full throttle when you do. I would recommend using 2 power supplies, the walwart power supply with the PE and a conventional transformer for the older engine.

Wow you nailed it. Every question answered. I am very impressed. I think I will print this out and use it as my guide to how I develop this next step.

Thank you very much.

Your welcome!
