The Men They Couldn't Hang might be worth a look, probably punk/rock slightly influenced by folk rather than the other way round.

Their "Rain, Steam and Speed" from Silvertown is a good song, named after the mid-19thC Turner impressionistic painting of a Great Western steam locomotive barrelling over a Brunel bridge (at 30mph, apparently).

Rain is the cold
Steam is the burn
Speed is the way the world turns (round)

Some men build a monument
Some men build a tomb
Some men move the world around
To give them breathing room
Some men carve a statue
Of Isambard Brunel
Some men carve a tunnel into hell

"It is not unfair to say they had a very Pogue-like feel with hard-driving versions of traditional tunes, hard-edged punk voice, and a hard-left political angle, epitomized by their first track, "Ironmasters," an angry recounting of the losing fight of unions against industry."(http://www.greenmanreview.com/tmtch.html)
