    This is creative idea. In my opinion truck sides for BR110 look quite OK. You can judge yourself. This engine still need to get decals and maybe some light weathering:

    I'll guess trucks are okay for Z scale. I am impressed, that locomotive looks very nice. And not to forget the amazing scenery. Well done. One would forget this is Z.

    Next Polish diesel will be much more complicated project. This is diesel engine SM42/SP42/SU42 (M-switching, P-passanger, U-universal):

    Quite a challenge... Biggest problem will be finding a suitable donor chassis. Here US proto type has a slight advantage, since locomotives are bigger that EU locomotives. Next link to my SW1000 might be of any help to you. Although I doubt that the MTL GP35/GP9 chassis can be lowered enough (if you still can get one).

    This is going to be "multi-project"
    - boogies - Marklin BR 212
    - chassis - main part: photoetched
    - motor: we already have one available but with only one shaft. We will check Rokuhan...
    - body - shell 3D printed (designer - Walt - @southernnscale )
    I do cooperate with a fellow modeller from Poland but still 300 km away from my place to make this real.

    BTW - great link about building the engine !

    MTL used a Maxon motor. I would need measure the motor. It is slightly bigger than the AZL motor. Someone here in the forum did use a Rokuhan motor repair a MTL GP35

    SM42 shell version 1.0 looked like this:

    Version 2.0 designeg by @southernnscale is much better in terms of proportions and additional elements:

    There are some parts that can be interchanged or placed on different location. That make possible to produce some versions of the engine. This concerns two types of roof, some variations of silencer covers and chimneys and radio antenna normally placed on the roof byt in some different locations.

    That is a great looking shell! Invest in some time to sand the printing artefacts flush. It will pay off in the end result.
    Looking forward to see the chassis design

    Main part of the body shell - primer printed:

    Looks fairly good already. After priming you can see where the shell still needs some cleanup. Small details remain problematic in z scale 3d printing. Here photo etching is prefered.

    Current AZL motor is bigger then the Maxxon motor. The first general AZL used a Swiss motor. Now they used Chinese motors.

    John, I don't believe that is correct. I believe the current motor that AZL uses is smaller than the old Maxon that MTL used, which is why AZL diesels are correct in width.

    Maxxon and Faulhaber motor have a 8mm diameter, AZL's China motor 7mm. AZL had also prototypical width with the 8mm motor, but used thin brass etched parts in the shell where the motor is installed rather than thick plastic like MTL to get the width right.
    Looking forward to see your chassis.

    Some progress with the shell - painting basic colour:

    Windows were made using Clearfix and stripes specific for this engine were added as well as handrails made of wire.

    It is good to compare the 2.0. shell with first design (thanks Walt !):

    This all looks great! looking at the printing of the shells you got don't seem to be there best printing. I have notice this when buying a shell at different times My most recent models seem to be real clean and not so many print lines and wax build up and look a lot cleaner then this model. You always do an outstanding job. I did a Z scale Shay shell and it came out much better. I don't know if they use other printers to catch up on orders but sometimes I wonder because the quality some time is outstanding and other times bad! This is the shay shell and it a clean print. I know they can't re-use the FUD material like they can with some of the others. This is my 0.1 print before cleaning you can see the difference. This one is really clean. I just wish they would get a good print every time. Keep up the great work always following your work.
