A new design guide for accessible inter-city train carriages covers just about everything you need to know. Oregon State University comprehensively researched design options for making passenger trains universally designed. Their findings are reported in Inclusive Universal Accessible Design Guidelines for Next Gen Passenger Rail. With the age of passengers increasing, they recognise the need for improved access for everyone.
The guide has a lot of technical data to support the design options. The focus is on wheeled mobility devices and assistance animals, but other groups are also considered. The guide discusses the trade-off between a larger restroom and the number of wheeled devices in a carriage. It doesn’t always mean a loss of seating for others. Folding seats are an option and they recognise that some wheelchair users will transfer to a regular seat. The lounge or buffet cars can also be universally designed. Sleeper cars, however, were not included in this research.
A good article for anyone involved in the design of rail infrastructure. Lots of detailed technical information including restroom fittings, public address systems and emergency procedures. Diagrams of layouts help with design explanations. While this document is based on USA requirements, it has relevance elsewhere.
Some newer Australian long distance trains have embraced inclusive design for all passengers. The image is from Queensland Rail.
