Awhile back I stumbled onto a website about Coconut Plantations.  One of the photos depicted a funky railbus that was used for carrying passengers and hauling coconuts in a trailer behind it to a processing plant.

I built the little bus on a Bachman On30 Trolley unit out of stryene and some bits from junk boxes.  The windshield wiper is a 1/24th scale car detail item.  The trailer is built up on a Bachman side dump ore car chassis. The trailer itself is from a 1/35th military kit.
