stovepipe

On the Visby-Västerhejde Railway there is a steam car. … The upperworks consist of a short clerestory coach body with end platforms and the engine chimney protruding from the roof like a stovepipe.

I'm sure the Brunel-designed stone-built structure would have had a hatstand for his trademark stovepipe. I can picture him rocking up there of a morning and lobbing it nonchalantly onto the hatstand.
