FFS! *Don't believe _anything_ on Wikipedia!

Wikipedia is a lot more reliable than many other sources of information,

Wikipedia can work well on narrow topics, usually where one or two
competent editors have written an article from scratch and it hasn't
yet been eroded. On anything broad-scale though, every idiot with a
coffee table encyclopedia of steam engines gets to play with it. The
top-level articles on Wikipedia are almost all dreadful - certainly
those on broad engine types or boilers.
