Civil engineering sites are rough places. Materials have to be carried about and dumpers, or even men and wheelbarrows, soon churn up the ground, adding to the difficulties. To overcome this transportation problem Road Machines (Drayton) Ltd., of Horton Parade, West Drayton, Middlesex, designed a simple monorail system. The first Mono-Rail Transporter was sold in 1949 and since then many have gone for use in all parts of the world. It is patented in 48 countries, spread over all five continents.

    The rail is 9in high. The running surface is 1¼in steel rod supported by steel plates 21¼in long, 6¼in high, tapered from 1in thickness at the top, to 2½in at the bottom. These plates, four to a 12ft length, are mounted on inverted 1½in by 3in channel forming the base of the rail. In the spaces between the supporting plates are square plates, each with a hole in its centre for attaching auto stops or buffers. The rail is made in 12ft and 6ft straight lengths and 6ft curves, of 12ft radius, twelve pieces to the circle. These lengths are nominal; for example a 12ft straight is 11ft 8in long, the other 4in being a short length incorporated in the rail stands. A 12ft straight weighs about 1½cwt. Special lengths are supplied to order.

Rich Morris started his monorail collection in 1975 when he purchased several Road Machines Mono-Rail products to add to his narrow gauge collection. He then became focused on the Mono-Rail and actively searched to add to his collection

One of his major accomplishments is the Monoloco. In 1998 he commissioned a steam monorail locomotive from Century Millwrights Engineers (works number 11003).

There have been a few steam monorail locomotives in the world, but the Monoloco is unique as it is the only one existing today that is operational
