45xx pony trucks

[steve howe]

Evening all,

I have a Mitchell 45xx, completed some time ago but not run much - until now, and I have discovered a problem with the pony trucks, particularly the front one, not making sufficient contact with the track and tending to either; skate along, or, drop off on curves. I guess the solution has to be some form of springing but I'm not sure how to arrange this without compromising the bogie swing.

Any ideas anyone?

When Guy Williams built this kit a long time ago he simply added a lump of lead to keep the pony down, as per his usual practice. I'm not sure there is any provision for springing but there certainly was space for a small slug of lead on top of the truck.

Does the truck drop when you lift the engine? Could be the pivot is keeping the truck unloaded.
