This is a human powered parade float for a Christmas night parade. It was built by the Human Powered Vehicle Operators of Ottawa (HPVOoO) http://hpv.tricolour.net . More details can be found on http://hpv.tricolour.net/train.html . The base platform is a human powered tandem recumbent tricycle towing a home made 4'x8' tandem axle 3/4 ton flatbed cargo trailer which in turn is towing a kid's wagon. The trike lies entirely underneath the bottom locomotive boiler line. The rest is added superstructure. The red, green and blue lights are 130m of 2.5mm electro-luminescent wire. The horn is a real diesel locomotive air horn.
