American Flyer Transformer 18B & 30B Parts List and Diagram
Attached is the American Flyer Train Transformer installation and wiring instructions for the American Flyer Transformer 18B & 30B. American Flyer Transformers were used to power both the trains as well as the accessories. In general the transformers had different power levels and sizes that enabled for more trains or accessories depending on the engineers collection. In addition, transformers often had multiple handles, as seen below, so that you could run multiple American Flyer locomotives at the same time and control the speed of the train.
If the Transformer has B in the name (ie. 1.5B vs. 1.5) it means the transformer came with a Circuit Breaker. If you wanted you could also use a Catalog #13 which was connected between the transformer and between the track and you could add a circuit breaker to prevent a fire from a short or transformer problem.
The high end models include meters for monitoring the voltage on the tracks along with the current being used by the train. They also include the Gilbert American Flyer “Dead Man” control – a handle that can be raised to stop the train and not needing to swing the handle to lower power setting. This feature can also be used to conveniently activate the locomotive reverse mechanism. The largest cases are used in the dual train control transformers No. 18B, No. 30B, No. 22060 and No. 22080. These large transformers can power two trains and many accessories. Again they are equipped with a variety of meters, lights and switches. The last case design is a revision of the plastic cases. The single train control version is the No. 22035 and the dual control version is the 22090. These are equipped with some features not previously available on Gilbert American Flyer transformers including a minimum voltage to hold in the reverse unit, push button for reverse unit activation (not in a transformer since the 1940’s).

Service Instructions for No. 18B & 30B Transformers
I am looking for the schematics to rewire the 18B or 30B. This exploded views helps as far as parts, but if I need to rewire transformer, i’ll need the wiring diagram itelf
John – Thanks for the comment. We are working on getting the rewiring instructions. Give us a couple of days.
Within the exploded view section of the service manual (about low center-left) there is a wiring diagram for the 18B/30B. While it doesn’t give this level of detail, the cord should be wired with line connected to the switch. (looking at the cord, one of the conductor insulation has ribs and the other is smooth. The smooth side is line and the ribbed side is neutral.) Best practice is to shut off the line with the switch.
If the detail level isn’t sufficient or you need clarification, let us know.
Thanks,
Bill
Hello & Help
I Need a complete and detailed wiring schematic/diagram for the American Flyer 30B transformer.
Please advise source where I might obtain.
Thank You

Hi David – I believe the wiring diagram and schematic are the same thing and should help you. Let me know if you are looking for something different?

any help will be appreciated…..
Do the AF transformers produce alternating current?
Do the AF transformers produce alternating current?
Yes, the transformers will provide alternating current at the same frequency (Hz) that is present on the line voltage input. In North America that is 60 Hz or 60 cycles per second. For the American Flyer DC motored locomotives Gilbert sold a separate No. 15 Rectifier to produce DC from the AC.
I have a 30B with what I believe to be a failing circuit breaker. It trips on loads that do not affect my other 30B. I plan on replacing the original breaker with an ATC type 1 breaker. My question is what was the original amperage rating on the 30B breaker?
