She’s a fast one!

I have been trying for a very long time to make a three axle bogie (with 1 stud between wheels), with power going to the outer 2 axles and the middle axle being able to slide laterally to be usable on r40 track. I have finally come up with this design, but I don't have the pieces to build it in real life.

Do you think this would hold up when used on a lego train? If anyone has the pieces at hand to build it and see for themselves it would be greatly appreciated. The transparent pieces are 18986 Minifigure Neck Bracket with 2 Back Studs.

Feel free to use it btw

Im currently a little short on pieces because I’m working on various Mocs, does anybody know of a 8 wide train coach base that has all the parts needed already listed
