Rail transit means the transportation form with the characteristics of huge transit capacity, high speed, safety, on-schedule, environment protection, energy and land conservation. Rail transit includes subway, light rail transit, magnetic levitation train, city railway, tramway, etc. It is getting more and more recognized that the upmost solution for city traffic is to give priority to set up rail transit as the core of city public transit system.

Rail transit systems are mostly built underground or on bridge way, which not only requires advanced technology but also reliability and safety. There are so many types of rail transit that a commonly agreed classification standard for technical properties doesn’t exist.

 

Challenges

Conventional organic materials cannot meet anti-fire requirements while conventional inorganic materials possess low compressive strength, a big insulation thickness is required for both materials, which decreases the inner space of the carriage while increases the weight.

Stringent requirements on thickness, overall weight and installation method of the insulation materials.

Extremely stringent requirement on health and safety issue for the insulation materials, such as toxic gas is disallowed during burning.

 

Benefits of aerogel insulation materials

Effectively reduces the thickness of and the space for insulation, which also reduces the weight percentage of the carriage.

Easy installation.

Excellent fireproof property.
