Aerorail

A Dallas company has proposed a SAFEGE-type system for several projects in the United States, including Seattle and Dallas. This system is very similar to the Mitsubishi systems in Japan, but has several significant differences. Steel wheels on steel rails are used instead of rubber. Aerorail uses steel wheels on steel rails to improve speed, eliminate "tire sing," and to use COTS (Commercial Off-The-Shelf) technology so important in holding down transit system costs. To reduce vibration, these wheels have an elastomeric component between the hub and steel tire.
