Assuming my old transformer isn’t safe to use anymore (which I will only know when I get my trains out of storage in a few months) what would be a solid starter transformer for a basic train layout under the tree with one train running at most. It also needs enough juice to throw two switches and maybe power an accessory (but not both at the same time). With train shows coming up I will check out the used market but if I need to purchase a new one what do you guys recommend?
Are there special concerns I should be aware of for AF trains, as opposed to Lionel? Will O-gauge ones (AC powered, not DC) put out too much voltage for AF trains?
If a transformer has not been abused or neglected most older transformers still work. Check the cord for cracking and replace if necessary. It really does not matter if you use A lionel or American Flyer transformer to run your American Flyer Trains. The main difference is that most Lionel transformers put out a higher voltage. I doubt that you will ever run your trains at max voltage so the higher voltage put out by Lionel transformers will have no effect on original flyer equipment. Even American Flyer transformers went from 15 to 18 volts during the early 50’s. I recommend that you have at least a 100 watt or higher rated transformer. This can run any Flyer train and lighted passenger cars . A example would be a Flyer 8B. I also have a modern MTH Z1000 that has the whistle and horn buttons that operate new Lionel Flyer equipment as well at American Models locomotives in additional to traditional Flyer equipment.
I use a 4B 100w 7-16v on my simple 4 by 6 foot oval. However I don’t have any switches or even any lighted cars at the moment so it’s more than adequate as a starter. But I agree with Major that the 8B is also excellent for the job especially since it gives you more lattitude for future expansion.
Thanks for your input. I was mostly concerned about the fixed/maximum voltages taps being used to run my switches or the accessory. I think the switches need 15v as does the accessory but if the Lionel puts out 18 I thought perhaps it would burn out the motors of my switches.
As for running the trains themselves, I agree that unless I put it on full it shouldn’t be a problem.
The switches are momentary contact and you should have no detremental effect using a slighter higher voltage. You can change the lights in accessories and switches to a higher voltage so they will last longer and run cooler. Also if you have multiple transformers for some items like lights you could connect then to the varible voltage post so you could adjust the brightness. I do this as I prefer less illumination from them. Makes night time more realistic IMHO.
Speaking of the American Flyer 8B, that is what I use to power my old steamer on my AF layout. Like the OP, I had my trains in storage for over 45 years before pulling them out two years ago. While the motors and reverse units needed some minor overhauls, the 8B transformer worked perfectly. You may be pleasantly surprised when you open up those storage boxes.
