The Lionel KW transformer was the second largest transformer Lionel made in the postwar era. It delivered 190 watts of power and provided two handles to control two trains. Internally, the design is very similar to the ZW. If the ZW was Lionel’s Cadillac transformer, the KW was the Buick. I always thought Lionels were overrated until I ran a 675 locomotive with a KW.
There was a time when nobody made modern transformers the size of a KW or ZW. Now that they do, the ZW and especially the KW cost a lot less. I remember when a reconditioned KW cost $200. Today you can get one for under $100. An as-is KW with minor issues will cost half that. These days, the KW is a bargain.
Our Dyson DC-14 pet vacuum started making a terrible loud, high-pitched noise one day. It still worked, mostly, but the noise was obnoxious enough that you wanted hearing protection while using it. And when I investigated further, I found the vacuum brush was not spinning either. I finally got around to fixing it.
A Dyson vacuum cleaner making a loud noise, a high pitched squealing noise, and the vacuum brush not spinning are all symptoms of the same 1-2 problems. The clutch is engaged and possibly damaged. It’s also possible the filters are clogged.
Lionel’s e-unit is the most common cause of trouble in vintage Lionel trains. Sometimes people bypass them or remove them entirely to avoid dealing with the problem. Or maybe someone attempted a repair in the past and you just bought the remnants. If someone did that and now you want to replace or rewire it, you need a Lionel e-unit wiring diagram.
I get a lot of inquiries about “the copper piece on a locomotive.” They mean a toy train locomotive. Depending on the make of the train, there may be one copper piece on the motor, or there may be two.
Here’s what those pieces are called, how to find them, and how to care for them.
In 1959, Marx attempted to cash in on the popularity of TV westerns by creating an 1860s style locomotive. Today, the Marx William Crooks locomotive is one of the rarer and more desirable Marx locomotives. You don’t often hear the words “rare” and “Marx” together.
The Marx locomotive was a recognizable model of the real William Crooks locomotive, a St. Paul and Pacific 1861-era engine that still exists today.
The Lionel 675 and its brothers, the Lionel 2025 and Lionel 2035, are among the best locomotives Lionel ever made. That said, they still need maintenance from time to time. That usually requires you to disassemble them. Here’s a guide to Lionel 675 disassembly that also applies to the 2025 and 2035.
At the last train show I attended, I bought a Marx locomotive that lacked a reverse unit. I found a mess of wires in its place, and of course it didn’t run. So I had to figure out how to wire a Marx motor without a reverse unit. When I wired it up to run correctly, it surprised me. It ran really nicely.
If you want to fix a Lionel train, what you probably really need to do is repair a Lionel train motor. There isn’t much to the rest of the train.
The motors tend to be pretty rugged and they’ve held up over the years. Most “repairs” are really more of a clean and service job, not unlike taking your car in for an oil change. Here are some general principles to follow when you clean and service a Lionel motor.
