This model allows for the conversion of a USA Trains S4 locomotive to an S2 without any modifications. Required components include:

  • 4 side frames
  • 8 bearing caps

Note: You may need to scale the bearing caps for an optimal fit. Additionally, 8 MF63ZZ flange bearings are required.

Credits to 512 Productions (Chris Murray) for the base design of the bearing caps and the MF63ZZ concept.
