Looking for mining locomotives

I AM looking for tips on tracing locomotives that worked in a mine where I live. I belong to the Skelmersdale Heritage Society and we try to keep memories of the town alive by tracing its history.

A mine that went into liquidation offered three locomotives for sale with their names. I would like if possible to trace them. I don’t know the etiquette of changing names etc. so they may have been consigned to history under other names, making my task impossible.
