The English Wikipedia page for "Railway platform height" only displays the text "Override this function." instead of the article requested. This page may be found at <http://en.wikipedia.org/wiki/Railway_platform_height>.
Which skin were you using?
I wasn't logged in, so it was using the Monobook skin.
I did some testing, it's probably not happening anymore. I've made a change in r54771 which will make this a PHP fatal error, which can be logged and dealt with more easily than a string sent to the output, but it's not live yet. Please reopen this bug if you see it again.
