Cover art for Bellerin' Plain lyrics by Captain Beefheart and the Magic Band

"Parapliers" is wordplay on parapluies, which means umbrellas. Also on pair of pliers.

There's a famous Renoir painting called Les Parapluies.

And looking forward along railroad tracks resembles an open pair of long-nose pliers. I agree with HarryIrene that it has a lot of imagery relating to trains. A bit like the verbal equivalent of those Futurist paintings of trains in motion.
