Lionel KW Transformer

  • I received a Lionel KW Transformer. I have no instructions on how to use it and how to wire it to the lionel track. I bought the Greenburg's Repair and Operating Manual for Lionel Trains and it does not cover the wiring to the track. On the back panel there are 6 outputs, what do I use? I have 2 tracks.
    Thank you,
    Justin

    If anyone has a instruction manual and could email me a copy, I would be very greatful.

  • The outer most terminals should be connected to your track. The top two terminals are the "U" terminals, and are internally connected together. These should be connected to your outer rails. The bottom left terminal is for the left handle, and the bottom right terminal is for the right handle. These should be connected to your center rails. The two center terminals provide fixed voltage, but I have never used it, so can't comment on that.

  • Contact Lionel customer service, I got a TW real cheap and it didn't have the manual with it. Customer service sent me a repro copy.

  • Since you already have the Greenberg book, take a look at the section, "Circuits with Common Ground" , which is located just ahead of the transformer listings. The KW is among those showing which terminals are to be used for ground, fixed, and variable outputs. Although terminal U is the most popular ground, terminal C can be used if your locos start too quickly at the minimum 6V you get when terminal U is used.
  • As stated above the ‘U’ is common and should be connected to the outside rails

    The ‘A’ and ‘B’ is variable 6-20 volts (to run the trains)
    The ‘U’ and ‘D’ is fixed at 20 volts
    The ‘U’ and ‘C’ is fixed at 6 volts
    The ‘C’ and ‘D’ is fixed at 14 volts

  • Tom has it correct. I have 2 of them. One I jsut bought that was new [yes, new] in the box and has instruction sheet. Shoot me an email and I will scan for you. Then you can print out.

  • The KW is a great transformer, very underrated among collectors and, I think, very underpriced considering its power. There are, though, a few things to be careful of before placing it in service. First, be sure the line cord and circuit breaker are OK. Then check the contact rollers for the two variable voltage taps. They wear out just like the ones in ZWs and the same replacement parts can be used in both transformers.
    One thing to be careful of when you hook it up: both sides of the 14 volt fixed output come from coil taps that are both above (voltage with reference to) the common or U terminal, so neither one can be connected to a common ground on your layout without shorting out part of the transformer secondary. If you use the 14 volt tap for accessories be sure that the accessorys metal base cannot come in contact with anything connected to the U terminal (such as the outside rails of your track).
    Hope this helps.

  • Does Lionel's R Transformer work the same way as the KW? I have my notes about the various back terminal combinations but I'm worried about hooking something up the wrong way.

    Bill, where do you live in Wayne? I'd like to get a copy of that - I can just pick it up from you.

  • Dear ChiefEagles, if you have scanned the manual for the ZW I would most appreciate

    an email copy of it.  I have attempted obtaining one from Lionel without sucess.

    Emailed you copies of 1033, KW and ZW.  Should be able to print from email.  Sorry for the delay, just looked at the topic.  Been on the IL's run most of the Christmas holidays.  Let me know if that did not get through.
