Locomotive, Einstein Equation

[Baluncore]

Do the Einstein field equations explain why this locomotive is sinking into the Bolivian sand?

They are responsible for it.

The paint makes the locomotive heavier.
I would not hide the obvious answer in a spoiler.

@ mfb. I think you must have quickly edited your initial post to insert the spoiler box.

What an idea you have just triggered.
Last month I purchased a rusted garden ornament from a scrap dealer. It was an historical Robey & Co portable steam engine from the 1880s. I will stabilise what remains and paint it to stop to rust.
What would an appropriate equation be? H₂O = MC² Will that make them think?

Probably you know of this stuff, but i'll mention it just in case.
i use a phosphoric acid based stabilizer with some chromates in it, Hardware and home supply stores have it under various brand names.. around here it's "Ospho" . It changes rust into a more stable black material.
It also etches aluminum so paint will stick. I used it on that pink boat with good results.
