The History of Optirail High Visibility Guardrail

The History of Optirail High Visibility Guardrail

Alpha Rail has been a leading manufacturer of pedestrian guardrail products since 1985. However, our Optirail has a history dating back to the late ‘70s!

In 1977, a designer by the name of Dr Douglas Stewart transformed pedestrian safety by inventing Visirail, a type of pedestrian guardrail that features offset vertical bars and see-through posts. Thanks to this design, pedestrians could be seen clearly through the guardrail panels and significantly reduced numbers of accidents, becoming the most widely used pedestrian guardrail product.

Dr Stewart did extensive research into road speeds and viewing angles to design three different staggered infill arrangements used on low, moderate, and high-speed roads. These became what we know today as V2, V4 and V8 staggers. Initially this design was patented by the designer, with a single manufacturing company based in Scotland having exclusive rights to make the product.

After some time, Alpha Rail acquired a license to manufacture Visirail along with some other companies, with each licensee having to create their own name for the product. Therefore in 1995, Alpha Rail’s Optirail High Visibility Guardrail was created and has proved to be extremely popular in towns and cities across the UK.
