Thanks!The likes of cuprinol will work well on those. It may not cover what looks like paint marks on the upper right one, so sand those off in advance.
Correct, they were never used as railway sleepers.The wood segments as per the picture are not railway sleepers*.
Genuine used railway sleepers usually have traces of toilet paper and other passenger detritus attached to them. Possibly more toxic then anything used to treat them.
Yep, along with the heavy metals, and a thing called arsenic... Strangely the EU legislators didn't focus on the long washed off piece of toilet paper.The creosote
...can I paint them using something like cuprinol? I'd like them a colour as opposed to a stain.

I'd suggest you research directive 2003/2/EC if you've any more questions about why used railway sleepers are treated as hazardous waste.
Yes. And if you read the above mentioned legislation or guidance, you'll know for what purpose they can sell them.Those salvage yards that sell reclaimed materials like Victorian red bricks, Bangor slates, etc, often have genuine railway sleepers. (Or they used to anyway). They look worn, especially on the edges and the have holes and imprints from the pins and clasps.
...for what purpose they can sell them.
I worked in a place before where one of the instruments contained arsine.
