The cylinder in this steam engine has a 3.5 meter diameter (from the website of the museum at http://www.museumdecruquius.nl/historie-cruquius/de-stoommac... from the photo of the machine room at https://www.flickr.com/photos/33129810@N07/4971573233 I guess it is at least 10 meters high, and that doesn't include the boiler room. So, I would guess this is a fairly close race.
