Thanks for the suggestion. I was aiming at the same one but wasn't about the outcome. Nice to have some experienced feedback :) Big kuddos for the explicit pictures Here is the update design. I had to reduced the lenght of the underneath tanks to make some clearance for the "stability" axles. Also tried to add an extra layer of tiles on the tanks to see how it could cover the small wheels but the gain is limited. It would be difficult to hide them completely on a "6-wide" train anyway. Same thickness for the tanks as the initial design. Tanks are less long. With a extra layer to try to extend the tank Last picture is to illustrate the clearance between the underneath tanks the extra wheels with the two above options

Thanks. Done some more reading as i'm new to this and it appears that mobile 2-wheels bogies do not work great. The 16 stud gap between the axles make to it goes thru the turns but it's quite terrible to the hear and to the sight :). I'm trying to figure out a solution either by adding a small wheels 2nd axle that could be hidden by the underneath decoration or couple both bogies with a flexible stick as seems somewhere on the forum. Technically, the first option works well but still have to see how it looks on the train. Still have to test the second one.

My mistake. The plate base is 24-stud long. The axles are 16 stud apart only. Both bogies are mobile on the current version (using 2x2 turn plate)

That is actually the first design i did but i need to adust the color choice to fit bricks availability. For the motor, either I go with the current PF train motor and use only one axle and mount it rigid to the rear and keep only the front bogie mobile. The base is only 24-stud so it should be ok on the turns but I don't really know as I'm new to Lego trains. The construction i used should allow me to keep the current lower decoration as it looks. Or I go custom with a 3D printed brace for an electric motor and hold onto a Technic bricks chassis.

Hi, I started my first MOC project to go along with my 3yo son's new interest for lego vehicule including trains. I foccused my attention on a common locotrator model i was use to spot in local french train stations: the Y-8000 serie. I chosed to keep it to the 6-widish range to fit a train he already has. Colors of the non-motorized version are based on existing models (Infra, Fret, ...). The color of the PF version are custom to fit the body color of the battery box and the IR sensor. "INFRA" color scheme "FRET" color scheme Power Function version (WIP): An air intake has been added on top of the engine for clearance for the PF wire. The motorized 2-wheels bogie still has to be design. Actual design only include PF battery box and IR sensor.
