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.
The Lionel Multi-control Trainmaster RW is a sturdy tin box of a transformer from early in the postwar era. The presence of a whistle controller is the only thing that really distinguishes it from a prewar transformer. Lionel made it from 1948 to 1954. If you want to know all about the Lionel RW transformer, you’ve come to the right place. You probably won’t find a copy of the original instruction manual online but this will tell you all you need to know.
Most buying guides for monitors assume you’re buying a really expensive monitor for gaming. But there’s a lot more to look for than refresh rate and response time.
A good monitor can last 10 years and multiple computers, so it pays to make a good decision when buying one, even when you’re not spending $500. There can be a significant difference even between two $100 models, or between a $60 model and a $70 model, that will save you money in the long run.
Want to repair a Marx 1209 transformer? There are two schools of thought. One is that small, sub-75 watt transformers aren’t worth fixing because they are so cheap. The other is that since they are so cheap, you have nothing to lose by trying.
Marx didn’t design its transformers to be fixed, but the design is extremely simple. The hardest part really is getting the case apart and then getting it back together. If Marx had designed them to be serviced, like its competitors did, they would have cost more, so we wouldn’t have as many Marx trains to enjoy today. So it’s easy enough to forgive Marx for this.
The Lionel LW Trainmaster is a 125 watt transformer that Lionel produced from 1955 to 1966. They are reasonably durable and Lionel made them for a long time. That means you can find them easily on the secondary market. They can be expensive if they have their original box and paperwork. But if you just want to run a train and don’t care about the paper, you can get a serviced LW for $50-$60, and an as-is one for under $40. At 125 watts, it’s the most powerful single-handle transformer of the postwar era.
The LW is a quirky transformer so there are some things about if you need to be aware of if you have other Lionel transformers, but as long as you keep those in mind, it’s a fine transformer that will serve you well. The quirks have nothing at all to do with reliability. Lionel just designed its layout a bit differently than many of their other models. In some ways it’s the ideal accessory transformer. We’ll cover that later.
One thing to keep in mind: Unplug the LW when you’re not using it. It doesn’t have its own power switch. I plug my transformers into a power strip and turn all of them on and off with the strip’s on/off switch.
The Lionel Multi-control 1033 is a 90 watt transformer produced from 1948 to 1956. They are reasonably durable and were popular in their day, which means there are still a lot of them floating around so they tend to be inexpensive. I paid $70 for one about 15 years ago but the price has come way down; today you can get a serviced 1033 for about half that, and an as-is one for $20-$25.
Even someone who has a larger transformer or multiple larger transformers for the layout might be interested in a 1033 for the test bench, as it has all of the functionality someone would need for testing locomotives and whistling tenders.
