    Some very nice locomotives have been marketed at some very nice princes. Well outside of my hobby budget. How difficult would it be to build a stream loco in z-scale? I'm thinking of the U.P. 844 fef-3 4-8-4. In n-scale for instance they have the very nice brass loco's and less expensive but nice plastic models. Is anyone scratch building loco's in z? Where would one start? What help is out there?
    Thanks

    First, you need the drive mechanism. So, $300 for a Marklin chassis. Where else are you going to get drive wheels?
    Then all the etchings you have to design, especially all the little support details.
    Parts like sand domes, steam cylinders, etc.

    Search for 'Berkshire' 'chris' and then cry. At the amazement and reality.

    Z-scale could use a nice 4-8-4, like AZL's Mikado.(y)

    SJ Z-man, you bring up some very good points making me think a lot. The drive mechanism is a major consideration. Having to build the wheels & rods would take some time and Marklin is not a consideration for me. Atlas makes 8 wheel drivers (the other Atlas) at a reasonable price. The motor & miscellaneous gears I can purchase. A chassis block I can machine. All the other stuff I can make out of styrene and brass. After all, what is a scratch build all about. I'm not saying it is going to be easy & it will take time. What I need now are some drawing, what is behind the front shield.
    Thanks

    I have been developing some power trucks/ chassis to use in various N, Nn3, and Z projects. I'm finally getting close to some final units ready for public consumption. A Z scale switcher is one that I should be assembling soon, powering an existing Shapeways body. The effort has been in getting reliable operation at reasonable scale speeds and excellent low speed performance for switching. It's been a real challenge but after countless hours invested working out the endless important details I've got a very nice running package. This could be the poster child for the saying, "The devil is in the details, but so is salvation".

    This chassis is a prototype that's under 9mm in height with a 44" wheelbase running on Z scale track.

    OK, --> I'm <-- interested :0 What is the motor voltage? So many small ones are 6V which pushes the limit with DCC.
    And, the mine cars. Don't see them on Shapeways.
    Interesting Track Gauge.

    I think you are sparking some serious interest here. What Z needs among other things, is a good running switcher. Do tell more.

    Those cars are from Roy Stevens on Shapeways. I will not be using those particular ones for my Nn3 mine loco package as I'll have the preferred link and pin arrangement also at a lower than standard Z height which is more prototypical. I'll also have several car styles including a similar tipper but also other typical coal and hard rock mine styles. I'll have an option for a standard height coupler but as low as the typical Mancha, Jeffrey, etc, battery style locos are (under 6 scale feet high) that really puts the coupler too high and not prototypical in that application.

    For switchers and such I'll have some truck and chassis combinations that will work for various available bodies in Z, Nn3, N, or HOn3. At present I'm looking at the Shay from Showcase Miniatures in Nn3 or N as well as Randgust's Climax, both Nn3 and N options. I understand that his Climax currently has no Nn3 option, only N, so this will be a first for that application. I'll also have a chassis for N scale PCC trolley that will afford nice control but more importantly a very tight, prototypical turning radius as well as all mechanisms below window height so they can have a believable interior. I think that's a first. And any of these will be able to be DCC equipped. Currently planning on ability to run 9 to 12 volt supply. I also will recommend a PWM controller for standard DC. That's for the obvious superb low speed control but when combined with the ability to run 9 to 12 volt supply it will allow a better led lighting scheme than many of the 6 volt units or standard controllers w/o PWM.

    Thanks for your interest.

    Interesting chassis design! It seems to run very smoothly. But for a switcher the chassis needs to be 7 to 8 mm max. to fit under the hood. I am still hoping someone brings out a small chassis with swiveling trucks.

    I've got several variations of chassis and power trucks in the works. One that I have as a sample that I will do is the Z scale Rebel Switcher from Stony Smith on Shapeways. I know that one will be doable with one of the variations. And the Nn3 Climax and Shay that I'm doing are eight wheel chassis running on Z track so I suspect there will be other Z scale things that will be doable. My main focus when this all started was an Nn3 coal mine loco and as that came together these other things were a natural progression.
