Question

Help answer this question below.

We have a 30,000 lb load (a box)
It sets on Tracks, small train tracks
It is supported by 8 standard new steel wheels, with roller barrings.

We need to know the force needed to pull it.

A ruff guestimate within 500 lbs would be great.

    You should probably specify more base data. It's hard to even guess if the rolling resistance and desired speed is not known.

    Without friction even a minuscule force would move it, but not at all fast, nor with reasonable acceleration.

    One also needs to know if the tracks are level or in an incline, or if they are on a curve
