Abstract
Abstract Disclosed herein is an improved structure for flexibly supporting electric rails (reaction rail or ''''secondary,'''' current energizing rail for vehicle mounted electrolinear motor, ''''stator'''' or primary, and safe distance signal rail) from main monorail girders. The new structure includes resilient vibration absorbers for silencing and for reducing noises generated by the travel of railway vehicles over a monorail of the hollow girder type. The vibration absorbers accommodate the proper and continuous alignment of the electric rail carried by the support structure, by means of limited displacement of the support structure with respect to the main monorail girder.
